Water Resource Inventory Areas in Puget Sound

The Washington State Department of Ecology and other state natural resources agencies have divided the Washington into 62 "Water Resource Inventory Areas" or "WRIAs" to delineate the state's major watersheds.

Climate change impacts on water management in the Puget Sound region

Climate change is projected to result, on average, in earlier snowmelt and reduced summer flows, patterns that are not well represented in the historical observations used for planning and reliability analyses by water utilities.

Modern Puget Sound timeline

The Puget Sound region has a long history that has shaped the culture and environment we experience today. View a timeline describing key events in the Puget Sound region dating from Washington statehood to the present.

Marine fecal bacteria

Fecal bacteria are found in the feces of humans and other homeothermic animals. They are monitored in recreational waters because they are good indicators of harmful pathogens that are more difficult to measure.

Relic gardens: camas in the San Juan Islands

A botanist believes Coast Salish tribes once favored small islands in the San Juan archipelago for growing camas, an important food staple. Her studies may also show the vulnerability of these relic gardens to climate change as sea levels rise.

Little sunshine, cold air temperatures, and higher river flows. Freshwater plumes extend far into the waterways. Chilly surface temperatures in Central Sound. First blooms begin in South Sound. A thinner freshwater layer at Mukilteo suggests a low discharge of the Snohomish river.
