Skokomish

Watershed Hydrology

The Skokomish Watershed (HUC 17110017) covers an area of 291 square miles in the Olympic Mountains of Washington State. It is home to a diverse range of aquatic and terrestrial species, including salmon and steelhead trout. The watershed is characterized by a Mediterranean climate, with dry summers and wet winters. Snowpack in the area is important for water supply, with snowmelt contributing to the Skokomish River in spring and summer months. Surface water in the watershed is influenced by land use practices, with runoff from logging and agriculture affecting water quality. The Skokomish River is dammed to create Lake Cushman, which serves as a reservoir for hydroelectric power generation. Climate change is expected to impact the watershed, with increased temperatures and variability in precipitation patterns. Restoration efforts are being undertaken to address degraded habitats and improve water quality in the Skokomish Watershed.
