Reservoir Levels Weather Hydrology

Donnell Lake in California is a hydroelectric reservoir that was created in the 1950s. The lake is fed by the Middle Fork Stanislaus River, and its primary purpose is to provide water storage for hydropower generation. The surrounding area is also home to several creeks and streams that contribute to the area's hydrology. In terms of surface flow, Donnell Lake is a significant provider of water for the surrounding areas, particularly during the dry summer months. The area also receives a significant amount of snowpack during the winter, which also contributes to the region's hydrology. While the primary use of Donnell Lake is for hydropower generation, it also supports various agricultural and recreational activities. Farmers in the area use the water for irrigation, and the lake is a popular spot for boating and fishing.
