The Alsea Watershed covers an area of approximately 644 square miles in western Oregon. The watershed is characterized by a variety of hydrologic features, including steep terrain, dense forests, and several small lakes and reservoirs. The watershed receives a significant amount of precipitation throughout the year, with an average annual snowfall of 130 inches in the higher elevations. The snowpack is an important source of water for the watershed, providing a steady supply of water during the dry summer months. The watershed is also home to several large reservoirs, including the Alsea Reservoir and the South Fork Reservoir. These reservoirs provide water for irrigation, hydroelectric power generation, and recreational activities. Interestingly, the Alsea Watershed has experienced a warming trend over the past few decades, resulting in reduced snowpack and earlier snowmelt. This trend could have significant implications for water management in the watershed in the coming years.
