On August 4, 2022, the Environmental Protection Agency (EPA) approved the 2022-2026 Action Agenda adopted by the Leadership Council as the Puget Sound National Estuary Program's (NEP) Comprehensive Conservation and Management Plan.
Low air temperatures, rain, and late snow accumulation pushed back the discharge of meltwater to Puget Sound this season. The water temperature in Puget Sound was mostly at expected levels, but cooler in South Sound by May. Central Sound saw more oxygenated conditions. This year, La Niña weather made flying for aerial photography challenging, but by June, sunny days made up for it, revealing a high number of schooling fish, unusually low tides, and a glimpse of macroalgae to come. Internal waves in Central Basin and Puget Sound, and the beauty of Puget Sound from the air, are a reminder of the unique place we live in.
The winter was cold and wet, resulting in a good snowpack in the mountains to sustain river flows into summer. In Puget Sound, saltier waters in summer transitioned to fresher conditions by fall 2021. Water temperatures in late winter 2022 are now colder and oxygen levels are high. From the air, Puget Sound looks spectacular, with few events to report. First signs of the spring bloom were visible in protected bays and passes. Port Susan and Carr Inlet already show sizable patches of drifting organic material. Small jellyfish patches were present in Eld Inlet.
The year 2021 was generally drier and warmer including a heat wave in June. Higher river flows followed a rainy and cloudy fall. In 2021, EOPS aerial images continued to capture the diversity of phenomena on the water, with support from its wonderful contributors who documented visible water quality issues across the larger Puget Sound region. With our Artists Corner and story maps on critters in the mud, we hope to continue to inspire, educate, and motivate our community to keep curious and watchful eyes over the environment.
The 2021 State of the Sound is the Puget Sound Partnership’s seventh biennial report to the Legislature on progress toward the recovery of Puget Sound. The document reports on both the status of the Partnership's recovery efforts and a suite of ecosystem indicators referred to as the Puget Sound Vital Signs.
Puget Sound National Estuary Program Synthesis of Integrated Floodplain Management in Selected Puget Sound River Deltas
A 2021 synthesis report from the University of Washington Puget Sound Institute synthesizes leading integrated floodplain management approaches to support the EPA-funded Floodplains and Estuaries Implementation Strategy.
The tenth annual Puget Sound Marine Waters Overview looks at marine water quality and other conditions in the region in 2020. According to the report, there were few extreme weather or ecological events in 2020, but overall, conditions in Puget Sound were generally warmer, sunnier, and wetter than in typical years. The overview also examines patterns and trends in numerous environmental parameters, including plankton, water quality, climate, and marine life.
This summer river flows were generally lower than in 2020. And in August, high air temperatures and low precipitation continued, following a drought emergency declaration in mid-July that affected also marine conditions. The higher-than-normal salinity anomaly which persisted during summer in Puget Sound marine water is, however, eroding away, and lower-than-normal oxygen conditions developed in Central Sound in the month of August. Many blooms and organic material were reported by citizens throughout summer, and by September many colorful blooms in bays across the region continue to be active. Patches of macro-algae and organic debris are still numerous in South and Central Sound and in Padilla Bay. Jellyfish are occurring in unusual places. While we document water quality issues, we are also showcasing the natural beauty of Puget Sound through photography.
A 2021 report commissioned by the Washington State Department of Natural Resources identifies potential actions at the state or local level, or in combination, that could further bolster shellfish bed recovery in support of the Puget Sound Partnership's shellfish bed recovery target.
The Nooksack River watershed spans part of the border between British Columbia and the State of Washington. In August 2018, the international, multi-agency Nooksack River Transboundary Technical Collaboration Group (TCG) was established to implement a three-year work plan to reduce fecal bacteria concentrations in the Nooksack River watershed. The 2020-2021 TCG annual report summarizes third and final year project activities and focuses on three of the watershed's transborder sub-basins.
Despite a La Niña, precipitation and rain have been lower since March, leaving only snow-fed rivers running high. Due to lower rainfall and warm summer temperatures the salinity of Puget Sound is now generally higher. Strong blooms and large patches of organic material and macro-algae are building up in many places and wash onto beaches. During very hot summer days, tidal mudflats and beaches can get really warm. Beach wrack can harbor increased bacteria numbers now. See SCUBA cleaning up at Redondo beach.
After a wet winter/spring transition it has been noticeably drier, warmer and sunnier. River flows are near normal levels and in Puget Sound and coastal bays salinity is increasing above normal. The spring bloom is developing but not very pronounced, yet, Noctiluca is already visible in southern Hood Canal. Suspended sediment near rivers and creeks, failing bluffs, and shellfish activities are frequent. Capturing herring spawning from the plane is informative; pilots share their observations.
A 2014 report from the Washington State Department of Natural Resources outlines a recovery strategy for native eelgrass in Puget Sound. The strategy is designed to address a target set forth by the Puget Sound Partnership to increase eelgrass by 20 percent in Puget Sound by 2020.
We are in a weakening La Niña, coastal downwelling has lessened and we are getting out of a cold and wet stretch, hurray. In March, rivers have almost returned to normal and carry clear water. It’s a good time to go diving if you don’t mind cold water. The productive season has only started in some places and patches of jellyfish are visible. Have a look at this edition and marvel about the secrets of the dead, or mysterious sediment clouds and the oil sheen spotted near Lummi Bay.
Residential shoreline loan program feasibility study: Developing a new Shore Friendly incentive to help Puget Sound homeowners finance beach restoration and sea level rise adaptation
The 2018 Shoreline Armoring Implementation Strategy identified development of new financial incentives as a near-term priority. This study, funded by the Habitat Strategic Initiative, assesses the feasibility of developing a Shore Friendly residential shoreline loan program.
The Benthic Index of Biotic Integrity (B-IBI) Implementation Strategy is designed to improve freshwater quality by analyzing the health and diversity of invertebrate populations in Puget Sound area streams.
Rivers are flowing higher than normal since 2020. Winter weather has been warmer and wetter. In marine waters, temperatures have become too cool for Northern Pacific anchovies to tolerate in North Sound. From patches of jellyfish and snow geese, to sediment and early blooms, there is more happening in the winter than you might expect. Puget Sound has many species worth showcasing such as the heart crab – a shy critter that wears its heart on its shell.
Priority Science to Support Recovery of the Puget Sound Ecosystem: A Science Work Plan for 2020-2024 (SWP for 2020-2024) describes the information, learning, and interaction needed to support the coordinated efforts to recover, protect, and improve the resilience of the Puget Sound ecosystem.

A new report from the Puget Sound Ecosystem Monitoring Program details the effects of a changing climate on Puget Sound in 2019, and documents how these changes moved through the ecosystem to affect marine life and seafood consumers.
After a relatively warm summer and fall, and La Niña forming in the tropics, stream flows in the Puget Sound region are now relatively normal. Summer in Puget Sound produced lots of algal and organic material in the water and on beaches, which by October have disappeared. Kelp beds look strong in northern Puget Sound and the Straits; and the harvest of the annual chum salmon run is in full swing in Hood Canal. Jellyfish aggregations are visible in Budd and Sinclair Inlets — and some of the jellyfish might conceal a beast of another kind within. Oil sheens on the water are currently numerous.
A 2020 Base Program Analysis from the University of Washington Puget Sound Institute presents an overview of the programs, policies and initiatives that support the Puget Sound Partnership’s Land Development and Cover Implementation Strategy.
A warm and dry summer ended with a smoky September due to massive wildfires that were followed by strong rain. As a consequence, muddy river plumes in Puget Sound are very visible, especially near the Nooksack River. During summer, many wonderful citizen contributions documented the large formation of organic material in Central Sound and helped us cover the gap in EOPS flight from April-September. By September when we started flying again, a few bays still had red-brown blooms. Nevertheless, schools of fish are abundant, and jellyfish are sparse, which is good news. Meet our new ocean acidification experts.
The Nooksack River watershed spans part of the border between British Columbia and the State of Washington. In August 2018, the international, multi-agency Nooksack River Transboundary Technical Collaboration Group (TCG) was established to implement a three-year work plan to reduce fecal bacteria concentrations in the Nooksack River watershed. This 2019-2020 TCG annual report summarizes second year project activities and focuses on three of the watershed's transborder sub-basins.

The Pathogens Prevention Reduction and Control agreement between the Environmental Protection Agency and the Washington State Department of Health focuses on the prevention and reduction of pathogen pollution in Puget Sound through the management of human and animal waste. The primary objectives of the agreement include restoring shellfish growing areas, avoiding shellfish closures, and protecting people from disease.
After a wet January, precipitation has been low and air temperatures have been cooler. As a result, rivers gages are lower than expected, a pattern that has continued since last year. In March we approached the coldest water temperatures of the year. Herring are spawning in Port Madison. Although these cool temperatures are good for herring, temperatures are close to the survival limits for anchovies. If you can handle these temperatures, now is a good time to go diving to benefit of good underwater visibility, just avoid windy days near wave-exposed beaches. If you are lucky, you might see the kelp humpback shrimp, a master of camouflage.
Social scientists at Oregon State University have been analyzing a trove of more than 17,000 public comments sent to the Washington state governor's southern resident orca recovery task force. The researchers have added the comments to a keyword database to look at public emotions and perceptions around the issue of orca declines.
The Washington State Department of Ecology has prepared a summary review of its Eyes Over Puget Sound surface condition reports from 2019. The year started with snow, and a summer drought kept river flows low. As a result, salinities in Puget Sound were elevated year round. Warmer surface water temperatures in spring gradually extended to greater depth by late summer. The spring bloom was strong, and South Sound provided optimal conditions for anchovies that showed up in high numbers. A coccolithophore bloom stained Hood Canal turquoise, and Port Angeles and Discovery Bay were colored red-brown by strong blooms. Noctiluca and macroalgae, both known eutrophication indicators in coastal regions, were abundant in Central Sound, and extended into South Sound and Whidbey Basin. Large numbers of jellyfish occurred in Quartermaster Harbor, Sinclair Inlet, and parts of Orcas Island.
The 2019 State of the Sound is the Puget Sound Partnership’s sixth biennial report to the Legislature on progress toward the recovery of Puget Sound by 2020. The document reports on both the status of the Partnership's recovery efforts and the status of a suite of ecosystem indicators.
After a dry early summer followed by more than expected rain, rivers mostly remained lower than in 2018. In October air temperatures dropped, but water temperatures remained warm enough for spawning anchovies in South and Central Sound and herring and salmon optimal growth in Whidbey Basin. By the end of October many red-brown blooms vanished, yet the waters of South Sound are still green, adorned with rafts of organic debris in many places. Read what happened the year before in the Puget Sound Marine Waters 2018 Overview.
A new report from the Puget Sound Ecosystem Monitoring Program says climate change altered the base of Puget Sound's food web in 2018, diminishing microscopic phytoplankton necessary for marine life. Scientists also observed lower abundances of fish, seabirds, and marine mammals.

This year, air temperatures were warmer than in previous years, and this pattern is predicted to continue. Precipitation was low and is now improving, yet river flows remain low. By August, Puget Sound surface water temperatures were 0.6 °C warmer across all regions; this could have shifted the timing of optimal temperatures for some marine organisms. In September, blooms are limited to inlets. Jellyfish are abundant in Sinclair Inlet, and anchovies reside in Eld Inlet. Macroalgae are still plentiful. Learn about the benefits of beach wrack and a DNA barcoding project supported by Ecology.
In July, the recent trends of warm, dry conditions lessened; however, river flows remain low. Extensive macroalgae drifted through South and Central Sound and washed up on beaches. Macroalgae growth is fueled by excessive nutrients and sunshine. When it washes onto the beach, it is called beach wrack, and it can be a health risk to beachgoers because of bacteria it can harbor. From our aerial photography, we saw that Southern Hood Canal looks tropical because of a bloom of coccolithophores coloring the water turquoise. Schools of fish congregate in South Sound and southern Hood Canal. Jellyfish are abundant in Quartermaster Harbor.
Warm and dry conditions this spring are predicted to persist into summer, resulting in saltier and warmer than normal Puget Sound water conditions. Early upwelling and a premature melt of the snowpack means nutrient-rich ocean water likely already entered Puget Sound. This sets the stage for a lot of biological activity. From the air, it is obvious that the productive season is in full swing. We saw large algae blooms in Central Sound along with abundant Noctiluca. Huge numbers of anchovies were documented in Case Inlet and other finger inlets in South Sound, attracting hundreds of marine mammals.
Washington and British Columbia residents are largely unfamiliar with the Salish Sea. A recent study conducted by the SeaDoc Society and Oregon State University reveals a need to improve geographic literacy and familiarity with the Salish Sea among those communities who share and live alongside this integrated transboundary ecosystem. This summary was provided by two of the collaborators on the survey, David Trimbach of Oregon State University and Joe Gaydos, Science Director at the SeaDoc Society.
Following a generally warmer and drier winter and then a cold spell in February, Puget Sound waters are cold for anchovies. The productive season is in full swing with algal blooms spotted in South Sound, Kitsap Peninsula, and Quartermaster Harbor. Jellyfish are abundant in some inlets, and Noctiluca stains the water orange in Hood Canal. We collect monthly data to keep you informed about the conditions around Puget Sound. Come into the lab and see how we assure the highest data quality from our field instruments!
A 2019 report from the Puget Sound Ecosystem Monitoring Program presents an overview of selected recent monitoring and research activities focused on toxic contaminants in the Salish Sea.
Although fall and winter were warm, February brought cold snowy weather and low river flows. Despite colder air temperatures, the productive season has already started in Hood Canal and Holmes Harbor. Puget Sound waters were warmer than expected through January, and the warmest waters were in Hood Canal, possibly creating a thermal refuge for cold-sensitive species such as anchovies. We saw lots of sea lions feasting on anchovies in Case Inlet, and we may have captured some herring spawning activity. Unusual for mid-winter, we saw jellyfish patches in Eld and Budd inlets. See the new publication about ocean acidification featuring twenty-five years of our marine monitoring data!

A guide from the Washington Department of Fish and Wildlife provides information for volunteers in the event of an oil spill in Puget Sound. It was produced by the University of Washington Puget Sound Institute with support from the Environmental Protection Agency.
In 2018, water temperatures were slightly warmer than normal. Aerial photos revealed many spawning herring and baitfish as well as algal blooms. We also saw abundant macro-algae, a persistent Noctiluca bloom, and countless red blooms. Were these observations related to the cool, wet spring followed by a warm, dry, and sunny summer? Or did the neutral boundary conditions in the Pacific Ocean also play a role? A full summary is available in the report.
A 2021 report published by Washington Department of Fish and Wildlife and Washington Department of Natural Resources describes a regional strategy to reduce shoreline armoring in the Puget Sound region.
The Puget Sound Action Agenda is a shared plan for Puget Sound recovery resulting from a collaboration by state and federal agencies, tribal governments, local governments, business and environmental groups, and others.
The Puget Sound Ecosystem Monitoring Program has released its seventh annual Marine Waters Overview. The report provides an assessment of marine conditions for the year 2017 and includes updates on water quality as well as status reports for select plankton, seabirds and fish.
A 2018 report published by the University of Washington Puget Sound Institute and the Washington Department of Fish and Wildlife brings together an assessment of key science and other knowledge related to herring recovery in the Salish Sea. The report was produced with support from the SeaDoc Society and received input from a cross-border team from state and federal agencies, universities and area tribes.
This fall, elevated air temperatures, lower precipitation, and lower river flows generally persisted; this aligned with fall and winter climate predictions. Following a warm summer, October water temperatures dropped back to optimal ranges for many fish. Puget Sound water has cleared and visibility has increased as the productive season ends making it easier to document jellyfish and schools of fish in the inlets of South Sound. While these flights generate a lot of attention, the majority of our monitoring in Puget Sound is now done via boat!
A report from the Washington Coastal Resilience Project provides an updated assessment of projected sea level change for coastal Washington State and its relationship to coastal hazards such as flooding and erosion.
A 2014 report prepared by Coastal Geologic Services, Inc. examines spatial patterns in Puget Sound shoreline characteristics at the parcel-unit scale. It was developed in support of a social marketing strategy by state agencies to reduce shoreline armoring in the region.
Air temperatures have remained high with precipitation and river flows below normal, extending the summer’s unusual conditions. Water temperatures were warmer in August, perhaps too warm for bull kelp and some salmon species in South Sound. In contrast, Hood Canal, North Sound, and the San Juan Islands provide optimal growth temperatures for herring and salmon. Many terminal inlets of Puget Sound are experiencing extensive red-brown blooms. Jellyfish patches are developing in South Sound finger Inlets and remnants of floating macroalgae occur in the nearshore areas of South Sound and in Useless Bay. At times floating organic material we see from the air ends up on the shoreline were our BEACH team documents it.
This is the 4th biennial science work plan (BSWP) developed by the Puget Sound Partnership’s Science Panel. This 2016-18 BSWP, like its predecessors, identifies specific science work actions to be done over the next 2 years and provides recommendations for improvements to the ongoing science work in Puget Sound. This version of the BSWP builds upon the Partnership’s Strategic Science Plan (2010) and carries forward the Panel’s thinking about recommendations and priorities as expressed in the preceding BSWPs. This version of the BSWP introduces 2 innovations: (1) top priority science work actions are identified within the BSWP and (2) this BSWP discusses the Panel’s perspective on science actions included as near-term actions (NTAs) in the accompanying Action Agenda.
Its summer! River flows are generally below normal levels in response to low precipitation and warm air temperatures. Algae blooms are causing intense red-brown colors in Bellingham and Samish Bays, as well as in some other bays. Infrared images revealed that the algal blooms are in water exceeding 15°C. These warmer waters increase the risk of harmful algal blooms if toxin-producing species are present. Large rafts of macroalgae are drifting at the surface in South and Central Sound, and are particularly extensive in Carr Inlet, Commencement Bay, and Port Madison. Our Washington Conservation Corps Intern shares her many perspectives on Puget Sound.
During June, near normal air temperatures and continued low precipitation have resulted in highly variable freshwater inputs to Puget Sound. A large Noctiluca bloom extends across the South Central Basin of Puget Sound. Coccolithophores are blooming in Hood Canal. Macroalgae is drifting as mats on the water in Port Madison, South Central Basin, and South Sound. They are also piling up on beaches in South and Central Puget Sound and Whidbey Basin. Juvenile fish are migrating out of the estuaries and meeting a complex thermal habitat. New infrared images tell the story. Meet our ocean acidification expert, Stephen Gonski.
Rainfall in May was extremely low: The third lowest amount ever recorded. Rivers are responding differently depending upon whether they received water from rain or snow, which is melting rapidly. With projected drier and warmer conditions, can the remaining snowpack maintain healthy streamflows this summer? Seawater is already getting saltier than normal in response to the lack of rain. We see algal blooms in many colors. What is that orange stuff out there? It’s a Noctiluca bloom and organic material drifting at the surface stretching from South to Central Sound and Whidbey Basin.
A report from the Washington State Department of Health outlines results from a series of projects funded by the U.S. Environmental Protection Agency's National Estuary Program in 2011. These projects addressed pathogen pollution in Puget Sound through the management of human and animal waste. Restoring shellfish growing areas, avoiding shellfish closures, and protecting people from disease served as the primary objectives.
The U.S. Environmental Protection Agency awarded a Five-year Puget Sound Tribal Capacity Program grant (Grant #PA-00J27701) to the Skokomish Indian Tribe. The tribe received approximately $1 million over a five-year project period (10/1/2010-9/30/2015). The purpose of the Puget Sound Tribal Capacity Program is to assist Puget Sound tribes in participating in the development and implementation of the Puget Sound Action Agenda.
A report from the Northwest Indian Fisheries Commission describes the results of a series of 97 tribal projects related to Puget Sound recovery funded by the Environmental Protection Agency.
In December 2005, Washington Governor Christine Gregoire outlined an ambitious vision for Puget Sound. She appointed 21 leaders, including representatives from building and timber industries, shellfish growers, agriculture and environmental interests, port authorities, and local, state, federal, and tribal governments to the Puget Sound Partnership. The Partnership was given a 10-month assignment to “develop recommendations for preserving the health and ecosystem of Puget Sound, and to help educate and enlist the public in achieving recovery of the Sound by 2020.” The report was published in December 2006.
By March, regional impacts of large-scale climate patterns normalized, and air temperatures, precipitation, and coastal downwelling were below normal. April brought abundant rain and rivers responded. With La Niña returning to ENSO-neutral conditions, will the favorable snowpack maintain beneficial streamflows through summer? In 2018, water conditions in Puget Sound are mostly expected, except in Hood Canal where conditions only changed recently. Many rivers and field drainage ditches release sediment. A strong red-brown bloom is present in Sinclair Inlet, a bright- brown bloom in Padilla Bay (Joe Leary Slough), and a bright green bloom in Bellingham Bay. It is colorful out there! You might see our team on the water sampling sediments this month.
Large-scale climate patterns and local weather patterns are returning to more normal conditions. La Niña helped build a favorable snowpack, projected to persist well into spring due to cooler weather. As a consequence, stream flows are largely normal. In Puget Sound, we see again normal water conditions and observe early spring blooms in Central Sound, northern Hood Canal, and Whidbey Basin. Herring are spawning in Admiralty Reach and further north. Salmon Bay in Seattle continues to have frequent oil sheens on the water.
Sediment Quality in Puget Sound: Changes in chemical contaminants and invertebrate communities at 10 sentinel stations, 1989–2015
A 2018 report from the Washington State Department of Ecology presents results from 27 years of sampling sediments and benthic invertebrates at 10 long-term stations throughout the greater Puget Sound area every year from 1989 through 2015.
The Washington Marine Resources Advisory Council has released an addendum to the 2012 report Ocean Acidification: From Knowledge to Action. The original report established a statewide strategy for addressing ocean acidification in Washington. The addendum identifies updates based on emerging science and management practices and is intended to be a companion to the 2012 report.
The Puget Sound Ecosystem Monitoring Program has released its sixth annual Marine Waters Overview. The report provides an assessment of marine conditions for the year 2016 and includes updates on water quality as well as status reports for select plankton, seabirds and fish.
After a dry and sunny summer extending well into October, air temperatures are cooler than normal and precipitation has increased allowing rivers to regain strength. Despite a dry summer, Puget Sound is fresher this year than the past 17 years. As of September, warmer temperatures remained in South Sound. In October, surface water in the Straits however began to cool and the influence of rivers can be seen in our ferry data. Leaves drift on the water in South Sound and smaller blooms are confined to inlets as the productive season winds down. Meet our new intern and discover if Puget Sound really has sea spiders.
The 2017 State of the Sound is the Puget Sound Partnership’s fifth biennial report to the Legislature on progress toward the recovery of Puget Sound by 2020. The document reports on both the status of the Partnership's recovery efforts and the status of a suite of ecosystem indicators.
Formaldehyde is often used to control parasites on hatchery salmon and trout. The U.S. Environmental Protection Agency and the Washington State Department of Ecology conducted a joint study of formaldehyde concentrations in effluent from hatcheries in the Pacific Northwest.
Warm air temperatures, abundant sunshine, and drier conditions persisted. River flows are lower in the north. Puget Sound waters are still fresher than in the past 17 years from the combination of abundant spring rain and weak upwelling bringing less salty water from the ocean. July upwelling was stronger, however. Warmer water temperatures are notable in parts of Central Sound, accompanied by large rafts of drifting macroalgae. Diverse blooms in colors of green, orange and red-brown are present in many inlets. Jellyfish abundance is lower this year. Find out how we assess if the benthos is changing.
July had warm air temperatures, sunshine, and an abundant snowpack. Previous months had higher river flows (bringing freshwater) and weak upwelling (low delivery of saltier water) which resulted in very low salinities in Puget Sound, especially in the South Sound. Water temperatures are expected and warmer in Central Sound. Above normal sunshine has made Puget Sound biologically very active! Intense and unusual blooms color Hood Canal (coccolithophores) and south sound inlets. Large mats of organic material containing macro-algae drift at the surface. Many schools of fish are visible though jellyfish were absent.
A biennial report produced by the Governor's Salmon Recovery Office provides stories and data about salmon, habitat, and salmon recovery in Washington, including Puget Sound.
The Kitsap Regional Shoreline Restoration Program is an effort to protect and restore the Puget Sound nearshore by supporting willing landowners who wish to remove bulkheads on their shorelines. The Kitsap Regional Shoreline Restoration Program was funded by Environmental Protection Agency’s (EPA) Puget Sound Watershed Assistance Program, Grant #PO-00J08501-0.
Cooler and wetter conditions early in 2017 have set the stage for a favorable supply of freshwater. River flows are all above normal due to melting of the abundant snowpack from warmer May air temperatures. This is creating significantly fresher conditions in Puget Sound surface waters. Algae blooms are limited to some yellow-green blooms growing in bays near the Kitsap Peninsula and blooms near estuaries of the Skagit, Stillaguamish, and Puyallup Rivers. Red blooms are present in rivers feeding into Willapa Bay. Also see what is “blooming” in the sediments of Puget Sound.
A 2017 report from the Puget Sound Ecosystem Monitoring Program presents an overview of selected recent monitoring and research activities focused on toxic contaminants in the Salish Sea.
This report describes how funding from the Environmental Protection Agency's National Estuary Program provided fiscal support to allow the Nisqually Indian Tribe to participate in all aspects of the Puget Sound Management Conference. Activities included participation on the region's Ecosystem Coordination Board, The Puget Sound Salmon Recovery Council, a local South Sound LIO (AHSS), Treaty Rights at Risk efforts and various committees and meetings to support the outcomes of the Puget Sound Action Agenda.
The year 2016 in pictures: After two years of very warm air and record high water temperatures starting with the Blob (2015) and followed by El Nino (2016), temperatures have fallen and remain slightly warmer than normal in Puget Sound. Very low summer river flows (e.g., Fraser River) reflect climatic predictions for the NW. Record temperatures and low salinities occurred alongside observations of abundant jellyfish, floating macro-algae, and Noctiluca blooms. Surprisingly, only South Sound developed very low summer oxygen levels in 2016. In the fall, La Niña came with a punch, rain increased, and air temperatures dropped. Will this be an unusual La Niña?
ENSO is in a cold phase (La Niña) and it is wetter and warmer than normal. Strong precipitation in October greatly improved Puget Sound streamflows. At the coast, we had strong downwelling. As a result, water temperatures, salinities, and oxygen in Puget Sound are returning to normal. While surface water in Puget Sound has cooled, it is still warmer than in the Straits. Surprisingly, masses of suspended sediment occurred east of Steamboat Island in Totten Inlet. We continue to see large jellyfish aggregations in finger Inlets of South Sound and slowly fading red-brown blooms.
A September 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 27 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on shoreline restoration and derelict net and fishing gear removal.
September is jellyfish season and they are everywhere in southern Puget Sound! Sunny, warm, and dry conditions promoted strong late-summer plankton blooms in colors of red, green, and brown, now widespread in many bays. In contrast, Central Sound looks clear with low algal activity. Southern Puget Sound has large floating mats of organic material and developed lower oxygen in August. Meet the Critter of the Month - The Sweet Potato Sea Cucumber.
The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Overview this week. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.
In July, conditions were normalizing, yet river flows remained lower, continuing into August. July also saw lower oxygen appearing in southern Puget Sound. By August, jellyfish are occurring in high numbers in Eld and Budd Inlet. South Puget Sound has Noctiluca drifting at the surface in large orange lines in many places and red-brown blooms widespread in finger inlets, as well as in Sinclair Inlet. Central Sound surface-water temperatures are high, still in the 60s, and algae are abundant. See what we are measuring to understand ocean acidification in Puget Sound.
A July 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 10 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on invasive species, toxics, oil spill, and integrated risk assessment.
Through June, air temperatures and sunlight were higher than normal. Recent rain generally improved river flows. However, the Fraser river flow remains extremely low, reducing water exchange with the ocean. Water temperatures are still breaking records, yet dissolved oxygen levels are normal. Coastal bays are influenced by upwelling and exhibit lower oxygen and higher salinities. Puget Sound algae are thriving with blooms observed in many South Sound inlets. Macro-algae is seen piling up on beaches and drifting in Central Sound. Jellyfish smacks are numerous in Eld and Budd Inlets. Our fliers notice seals hanging out at the beach!
Record-breaking warmer and fresher water in Puget Sound. May-June conditions are more unusual than last year. Recent rain brought river flows close to normal but water exchange in Puget Sound remains weak due to low Fraser River flow. Phytoplankton blooms and organic material are visible in some areas of Central and South Sound but not in others. Noctiluca, while absent in Central Basin, was reported in unusual places. Jelly fish occur only in some south sound bays. Follow our BEACH program kick off, discover the Stinkworm, and find good underwater visibility for diving.
Protecting Puget Sound watersheds from agricultural pollution using a progressive manure application risk management (ARM) system
Throughout the Puget Sound region, impacted and poorly managed agriculture has been repeatedly advanced as a leading contributor to surface and ground water pollution, particularly during the winter months. A study conducted from 2010 - 2015 aimed to develop an Application Risk Management (ARM) System to minimize pollution from manure in Whatcom County.
A 2015 report from Snohomish County, King County and the Tulalip Tribes outlines protection strategies for salmon and salmon habitat within the Snohomish Basin.
Spring air temperatures are higher - it has been sunny and dry. The snowpack is quickly disappearing as temperatures are up to 7 °F warmer at higher elevations. Snowmelt-fed rivers are running very high. How does this affect water quality in Puget Sound? A strong spring phytoplankton bloom extends across Puget Sound and the Strait of Juan de Fuca. Water temperatures are still higher than normal and jellyfish are already numerous in southern inlets. The high biological activity is causing organic material to drift at the surface and wash onto beaches. Do you know how fast a Sand Star can move?
This report summarizes activities and accomplishments completed under the grant PO-00J100-01 from September 13, 2010 to December 31, 2015.
Despite warmer air temperatures, normal snowpack in the mountains suggest that summer freshwater flows into Puget Sound might be higher than last year. As of April, the spring plankton bloom has extended across Central and South Puget Sound. Ferry data shows chlorophyll increasing after March 25 and expanding across the area. With water temperatures above normal as a carry-over from 2015, jellyfish patches are numerous in inlets of South Sound and in Sinclair Inlet, unusual for this time of year.

Building Squaxin Island Tribe capacity to implement the 2020 Action Agenda for Puget Sound and the EPA region 10 comprehensive conservation and management plan
This 2015 report from the Squaxin Island Tribe details the projects it undertook with funds received by the EPA for the implementation of the 2020 Puget Sound Action Agenda. These projects include the restoration of the Shelton Harbor shoreline and a pelagic food web study.
In response to warm and wet conditions, rivers have been running high. Salinity in Puget Sound is notably lower. Below a cooler surface, water temperatures remain high, especially in Hood Canal. We still see numerous jellyfish patches in Puget Sound inlets. Phytoplankton blooms are going strong in Hood Canal and Henderson Inlet, and picking up elsewhere. Many places showed long stretches of suspended sediments nearshore, a sign of potential shore erosion. Check out the critters inhabiting the sediments of Puget Sound.
A 2016 technical report from the Washington Department of Fish and Wildlife and the Cascadia Research Collective details the decline of the harbor porpoise in Puget Sound in the 1970s and reports that species numbers have increased over the past twenty years likely due to outside immigration.
The year 2015 in pictures: Jellyfish patches persisted through the entire year in response to the exceptionally warm water caused by the Blob. Sediment loads are high as snow melts fast in the winter of 2015. Unexpected phytoplankton species occur in some bays in spring. Noctiluca, jellyfish and macro-algae appear in high numbers when rivers drop to record-low flows in early summer. Low river flows slow the renewal of in Puget Sound throughout summer and fall and jellyfish patches reach record highs.

The 2015 State of the Sound is the Puget Sound Partnership’s fourth biennial report to the Legislature on progress toward the recovery of Puget Sound by 2020. The document reports on both the status of the Partnership's recovery efforts and the status of a suite of ecosystem indicators.
This report communicates findings of a social science study conducted between July 2013 and December 2014 on a focal domain of human well-being: sense of place.
Puget Sound is starting to normalize in response to fall conditions with cooler air temperatures, rain, and recovering river flows. We are seeing fewer algal blooms, jellyfish, and macro-algae as salinities become more normal. Yet warm waters persist and El Nino and the Blob are likely to affect Puget Sound throughout the winter. The Nisqually River fared better through the drought than other rivers and best management practices have been improving its water quality. EOPS and ferry monitoring gain recognition with a national award for innovation!
A 2015 NOAA report creates an updated and comprehensive list of the fishes of the Salish Sea.
Coastal recreation, tourism, and ethical or existence values are among the most important ecosystem service (ES) benefits identified by Puget Sound stakeholders (Iceland et al, 2008).

This report focuses on economic, social and cultural values inextricably linked to ES benefits in the context of ongoing efforts to restore and protect the Sound.
In the 1940s, harbor porpoise were among the most frequently sighted cetaceans in Puget Sound, but by the early 1970s they had all but disappeared from local waters. Their numbers have since increased, but they remain a Species of Concern in the state of Washington. This in-depth profile looks at harbor porpoise in the Salish Sea, and was prepared by the SeaDoc Society for inclusion in the Encyclopedia of Puget Sound.
Air temperatures are warm and Puget Sound continues to show record high water temperatures. Some rain has returned to our region, yet river flows remain unusually low. Puget Sound is saltier than normal allowing oxygen-rich surface waters to more easily mix to greater depths. Lower oxygen was measured only in the Coastal Bays, Hood Canal, and South Sound. Large jellyfish aggregations continue in South Sound, the Kitsap Peninsula, and East Sound (Orcas Island). Sediment plumes in Bellingham Bay form unique patterns. Warm waters and sunny conditions fostered green tides, raising a stink along some local beaches.

Although overall eelgrass abundance appears to be stable in Puget Sound, some local areas are showing declines. A 2014 report from the Washington State Department of Natural Resources looks at the potential impact of increased nitrogen on eelgrass health.
Air temperatures have been slightly warmer and river flows are higher. Blooms are present only in Whidbey Basin and isolated bays. The water column otherwise is relatively clear. Sediment rich water is entering from the Stillaguamish River. Debris lines were visible in Hood Canal and North Sound. Multiple reported oil sheens seen in Lake Washington Ship Canal. Generally, the year 2014 started colder and saltier throughout Puget Sound. Oxygen is lower in Whidbey Basin, Central and South Sound, but higher in Hood Canal. Upwelling favorable conditions stimulate a spring phytoplankton bloom off the Washington coast.
A 2014 report describes a study of socio-cultural values associated with blueback salmon in the Quinault Indian Nation. The blueback salmon (Oncorhynchus nerka) is a unique strain of sockeye that returns primarily to the Quinault river system.
Harbor porpoise (Phocoena phocoena) are one of the most frequently sighted cetaceans in the Salish Sea. Anecdotal information, possibly supported with stranding encounter rate data, suggests that harbor porpoise may have increased in Puget Sound, or have shifted their distribution back to Puget Sound relative to earlier decades.
Harbor porpoises were once common in Puget Sound, but had all but disappeared from local waters by the 1970s. Regular and numerous anecdotal sightings in recent years show that populations of these cetaceans are now increasing and may be approaching their former status. The attached document from NOAA Fisheries describes harbor porpoise numbers and their geographic range in Puget Sound as of 2011.
River flows are above normal and air temperatures are increasing slowly. The spring phytoplankton bloom is slow to develop with visible blooms limited to smaller bays such as Sequim and Bellingham Bays. Noctiluca observed in East Sound on Orcas Island, coinciding with high numbers of jellyfish. Debris lines are mostly confined to Hood Canal. Pockets of colder water observed in Central Sound and Hood Canal, likely from the colder, saltier conditions that developed during the winter in the northern regions. Oxygen is variable yet close to expected ranges. Sizable oil sheens were sighted in Gig Harbor and Carr Inlet.
Multiple algal blooms in South Sound and Main Basin. Ferry and satellite images confirm center of algae bloom in the Main Basin and indication of a bloom in Carr Inlet. Oxygen levels are increasing on moorings. Oil sheen in Colvos Passage.
A Washington State Department of Ecology report establishing benthic indicators for Puget Sound. Benthic macrofauna are known to be good indicators of the status of marine environments, and benthic indices are often used as an assessment tool.
Air temperatures have fallen due to unusually weak northern winds bringing in cold air. A dry beginning to winter causes low river flows. This dry winter brings new Puget Sound conditions with colder saltier waters observed in the northern regions. Oxygen has stabilized again within expected ranges. Suspended sediments along wind and wave exposed beaches add artful brushstrokes to the Puget Sound waterscape. Jellyfish are still going strong in Eld Inlet. Oil seen leaking from a boat in Commencement Bay and Ecology’s Spills Program responds. Our intern, Clifton, brings renewed passion to monitoring!

But the region’s forage fish may be vulnerable on a variety of fronts, according to a new study panel report from the University of Washington Puget Sound Institute. Download the panel's summary and proposed research plan.
The year 2013 in pictures: Low oxygen conditions persisted from January into August and broke a two-year anomaly of more favorable water quality conditions (lower temperature and salinity and higher dissolved oxygen). Dramatic Noctiluca blooms appeared one month earlier than normal (May), lasted for two months, and coincided with lower oxygen. Large jellyfish patches persisted over the winter but then were less visible for the rest of the year. Large drifting algal mats appeared in August.
Every two years the Puget Sound Partnership is required to assess the status of scientific research relating to the recovery of Puget Sound, in a document knows as the Biennial Science Work Plan (BSWP). Among other tasks, this entails making an inventory of all ongoing research projects in the current biennium (2011-2013). We are posting this (draft) inventory of recovery-relevant research projects here to make the information generally available.

After weeks of clouds and warmer air, blue skies and cold temperatures set in. Strong tidal fronts and sediment-rich brackish plumes leave Whidbey Basin and move into Admiralty Reach. A pod of Orcas follows the edge of the plume heading north! Red-brown blooms continue in Henderson, Eld, and northern Budd Inlets. Long organic debris lines are numerous in northern Budd Inlet, Hood Canal, and in Central Sound north of Edmonds (Triple Junction). Conditions in the water column in Puget Sound continue to normalize after seven months of lower oxygen. Water is very clear for this time of the year, particularly in the north.
This report is published as one of a series of technical inputs to the Third National Climate Assessment (NCA) report.
This thesis discusses the Glaucous-winged Gull (Larus glaucescens) as an indicator of ecosystem change in the Salish Sea region.
The 2013 State of the Sound is the Puget Sound Partnership’s third report to the Legislature on progress toward the recovery of Puget Sound by 2020. The document reports on both the status of the Partnership's recovery efforts and the status of a suite of ecosystem indicators.
Puget Sound conditions are normalizing after seven months of lower oxygen. Calm, dry, cool, and foggy mornings abruptly changed on October 28 to sun and strong northerly winds. Red-brown blooms and abundant jellyfish in south Puget Sound inlets appeared as we flew to the coast. Blooms were still visible near ocean beaches and inner bays. Grays Harbor had abundant surface debris with green algae in North Bay. We spotted red-brown blooms in rivers and sloughs in Willapa Bay, as well as schooling fish near sandbanks. Many patches of suspended sediment appeared in shallow water unrelated to tidal currents and remain unexplained.

Sun and high air temperatures warrant en route ozone measurements for model validations. A furry visitor takes a rest on the float plane. See the spotlight on our pilot, Joe Leatherman. High river flows lead to striking fronts of turquoise-colored water carrying glacial flour in many northeastern regions. Satellite and aerial images show widespread phytoplankton blooms in Whidbey Basin, Hood Canal, South Puget Sound, and West Bay of Orcas Island. Numerous large debris patches are observed in Hood Canal, Central Sound, and South Sound Inlets. After two years of colder temperatures and higher oxygen, Puget Sound waters are returning to expected or lower dissolved oxygen levels.
Warm air temperatures and increases in flows from glacier-fed rivers give rise to dramatic images in the San Juan Islands. Warm surface temperatures in South Sound foster abundant red-brown blooms in southern inlets. Similar blooms are happening in the inlets of the Kitsap Peninsula. Large drifting algal mats in Central Sound, Sinclair Inlet, Hood Canal and Padilla Bay will likely end up on nearby shorelines soon. Jellyfish abundance has dropped. This year, dissolved oxygen levels in Puget Sound waters quickly decrease to levels of the previous decade.

Abundant sunshine gives rise to large algal mats in South Sound, Hood Canal, and Sinclair Inlet. Red-brown algal blooms dominate in Budd, Totten, and Eld Inlets and jellyfish begin to increase. Northerly winds push algal blooms from Whidbey and Central Basins past Seattle and a bloom in northern Hood Canal southward. Satellite thermal imagery shows patterns of near-surface mixing and injection of nutrients into the surface layer. Glacial-fed rivers deliver glacial flour into Commencement Bay, stratifying the water and supporting different colored phytoplankton blooms (green, brown, and red). Since the beginning of 2013, dissolved oxygen is dropping below expected values.
A stunning view of a second large Noctiluca bloom captures the attention of many living near Puget Sound. Favorable conditions support several regional phytoplankton blooms. Red-brown blooms in Port Townsend, Discovery Bay and Bellingham Bay. Large algal mats or organic material particularly in Samish Bay. Jellyfish patches increasing in Budd, Totten and Eld Inlets.

Sediment health in Central Puget Sound has shown a recent steep decline, according to a report by the Washington Department of Ecology. The report compares monitoring data over a ten-year period between 1998/1999 and 2008/2009.
This 2004 report looks at the status of Washington's four killer whale populations.
After 2-years of conditions favorable for water quality, with colder temperatures and higher oxygen, Puget Sound water conditions are closer to expected again. This year phytoplankton blooms and seasonal oxygen maxima are notable, while extensive Noctiluca blooms showed up early following a period high freshwater inputs and milder weather conditions. The Fraser River sediment influence is very strong north of San Juan Islands and warm, fresh water is entering Central Puget Sound from Whidbey Basin. In the past few weeks river flows and air temperatures have been higher than normal and now are decreasing.
The Washington Department of Fish and Wildlife recently released a Bat Conservation Plan for the 15 species of bats found in Washington State. All but four of these species occur within the greater Puget Sound watershed1, including:

For the last week sunshine was low and rivers and air temperatures have been higher than expected due to prevailing southerly winds. Heavy rains have resulted in long foam lines and large river plumes that are filled with sediment. Jelly fish patches have persisted through the winter in smaller bays. Are higher oxygen conditions seen over the last 2 years starting to disappear? We were busy in 2012 and spooled out 37 miles of CTD line to explore the depths of our estuaries!
Lower than expected air temperatures and sunshine are now both increasing; rivers are generally running high. Willapa Bay unfolds its beauty from a bird’s-eye view. The spring phytoplankton bloom is picking up in Puget Sound. A large red-orange-brown bloom persists in southern Hood Canal at a scale sufficient for the MODIS satellite to pick up. Jellyfish are still going strong in southern inlets. Ocean climate indices (PDO, NPGO and Upwelling Index) explain much of the variability in Puget Sound temperature, salt and oxygen. Nutrients, however, are steadily increasing while sub-surface algal pigments (chlorophyll a) are declining!

In an effort to understand how residents of Puget Sound view social and environmental change in their region, researchers at the Carsey Institute at the University of New Hampshire and the National Oceanic and Atmospheric Administration collaborated on a public perceptions survey, visualization models, and stakeholder workshops in 2012. The results of their research are available online, and in the three attached PDF documents.
The weather has been warm, cloudy with weak winds from the south. Surface water temperatures range from 8.5-9.5°C. River flows are dropping below expected levels, yet the seasonal increase in freshwater can be clearly seen. Debris lines are numerous near river estuaries. Algal biomass is down but jellyfish aggregations continue to go strong in terminal inlets.
A recent report by an independent science panel reviewed data on the effects of salmon fisheries on Southern Resident Killer Whale populations. The report was released on November 30, 2012 and was commissioned by NOAA Fisheries and Oceans Canada.
Sweetening the waters - the feasibility and efficacy of measures to protect Washington’s marine resources from ocean acidification
Washington State's ocean acidification initiative began with the launch of Governer Christine Gregoire's Blue Ribbon Panel on Ocean Acidification in December 2011. The initiative is the first of its kind in the country, and a report commissioned by the Global Ocean Health Program was released in November 2012. The report is a first step towards assessing and improving the tools at hand.
