Puget Sound

Puget Sound is critical to our environment, culture, and economy. About two-thirds of the state’s population lives in the Puget Sound region. Our nation’s second largest marine estuary faces a number of challenges related to population growth and development, as well as habitat loss and multiple sources of pollution.

We work in collaboration with a wide range of local and tribal governments, other state and federal agencies, non-profit organizations, and private sector partners to use the best available science and research to better understand and counter challenges facing Puget Sound.

We are building lasting partnerships, working together, pooling resources, and making smart investments to restore, protect, and preserve the health of Puget Sound, now and for future generations.
