The City of Seattle manages two large, regional watersheds, the Cedar River and the Tolt. These regional watersheds supply Seattle and surrounding communities with drinking water and serve as a home for wildlife and salmon. The Habitat Conservation Plan and Wildland Fire Crew protect this pristine environment.
How snow becomes our drinking water
Snow accumulated in our mountain watersheds assure a good supply of fresh water in the spring and summer. The water goes to our city as drinking water and serves species like salmon and steelhead trout.
As early as 1917 the City measured snow depth in the Upper Cedar River Watershed. This measuring tree near Bear Lake shows Seattle Water department employees recording 10 feet of snowpack that year.
Deep in the Cedar River canyon, Lower Cedar Falls is so remote that the only way to see it is by helicopter. During late winter and spring, snow surveys by SPU Watershed Protection staff are performed by helicopter to survey all the sites in one day throughout the upper Cedar and Tolt River watersheds.
