The Queets-Quinault Watershed (HUC 17100102) is a large, mountainous watershed located in the Olympic National Forest in Washington State. The watershed covers approximately 1,029 square miles and is characterized by its rugged terrain, dense forests, and numerous lakes and streams. The hydrology of the watershed is dominated by the Queets River, which is fed by several smaller tributaries and snowmelt runoff from the surrounding mountains. The snowpack in the watershed is typically deep and persistent, with the highest elevations receiving over 200 inches of snow annually. Surface water in the watershed is generally of high quality, with low levels of pollutants and sediment. The watershed's reservoirs are primarily used for hydroelectric power generation, and the water quality is closely monitored to ensure that it meets state and federal standards. Interesting climatic facts and trends in the watershed include the high levels of precipitation and snowfall, as well as the occurrence of severe winter storms that can cause flooding and landslides.
