Despite the Puget Sound region’s reputation for abundant water, communities across western Washington are increasingly confronting summer water stress. Hotter, drier summers, declining snowpack, and rapid population growth are reshaping the timing and reliability of freshwater availability in the Puget Sound Region.  Over the next 40 years, the region is expected to add roughly five million residents, increasing pressure on water infrastructure, freshwater ecosystems, and instream flows that support salmon and other species.
