The weather has been relatively cloudy, warm and dry. We found less debris in the water but saw several large tidal eddies and suspended sediment plumes. Jellyfish continue to go strong this winter. We also observed early algae blooms in Hood Canal and Eld Inlet as well as multiple oil sheens in Seattle waterways. Listen to our marine flight technician discuss EOPS on the radio.

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.

Pollution of the rivers, creeks, bays, and open waters of Puget Sound comes from a variety of sources and travels along many pathways. Spilled oil products and fuel, deposition of air pollutants, legacy toxic pollutants, disease-bearing and illness-causing organisms from failing and poorly maintained on-site sewage treatment systems, fertilizers, erosion, and the runoff from roads and parking lots all find their way into the waters of Puget Sound, where they harm fish and wildlife and create direct health risks to people. Polluted waters reduce ecosystem services – shellfish closures, beach closures, impacts to recreation, impairments to sources of drinking water, loss of cultural resources, consumption warnings for fish, and low oxygen conditions that kill marine species. Increasing numbers of people, cars, and pavement mean more pollutants enter our waterways in higher concentrations, and at a faster rate. Pollutants also enter waterways directly through point source discharges from commercial and industrial sites.

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.

The following fact sheet provides an overview of low oxygen conditions in Puget Sound. It addresses some of the related causes and concerns that have been identified by scientists in the region. The overview was prepared in conjunction with a series of workshops on hypoxia and nutrient pollution presented by the University of Washington Puget Sound Institute. 

A summary of data on ecosystems designated as Critical Areas (formerly Environmentally Sensitive Areas) in San Juan County, including recommendations for management.

The Nisqually tribe has over 650 enrolled members. Most live on or near the reservation, which was established by the Medicine Creek Treaty in 1854. According to legend, the Nisqually people migrated from the Great Basin thousands of years ago, crossing the Cascades and settling in what is now Skate Creek. The tribe is one of the largest employers in Thurston County. Nisqually Tribe A...
