Prosser Creek Reservoir is a man-made lake in Nevada County, California. It was created in 1962 as part of the Prosser Creek Dam project by the United States Bureau of Reclamation. The reservoir has a capacity of 49,000 acre-feet and is operated for irrigation, flood control, and recreation purposes. The hydrology of the reservoir is mainly fed by the Prosser Creek along with tributaries from the surrounding mountains. The surface flow is mainly from snowmelt during the spring and early summer months. The snowpack providers are the Sierra Nevada mountains, which provide most of the water supply for the region. The reservoir provides water to agricultural lands in Nevada and Placer Counties and also serves as a popular recreational spot for boating, fishing, and camping.
