Union Valley is a reservoir located in El Dorado County, California. The reservoir was created in 1963 with the construction of the Union Valley Dam, which is part of the American River watershed. The hydrology of Union Valley is primarily fed by the Rubicon River, and the reservoir provides water for hydroelectric power generation, irrigation, and municipal use. The area is also popular for recreational activities such as fishing, boating, camping, and hiking. The surrounding forests and hills are home to a diverse range of wildlife, including deer, elk, and black bears. The Union Valley Snowpack, which is a significant provider of water to the region, is particularly important for the agricultural community, with crops such as potatoes, grapes, and apples requiring water from the snowpack for irrigation.
