East Park Reservoir is a man-made body of water situated in the foothills of the Northern California Coast Range. It was built by the Bureau of Reclamation in 1967 to store water from Stony Creek, a tributary of the Sacramento River, for agricultural purposes. The reservoir has a capacity of 150,000 acre-feet and covers an area of 11,500 acres. It provides irrigation water to over 36,000 acres of farmland in Colusa and Glenn Counties. The reservoir is also a popular recreational area, attracting campers, anglers, and boaters. The hydrology of the reservoir is primarily dependent on the snowpack in the mountains to the west and the surface flow of Stony Creek. The reservoir is managed by the Bureau of Reclamation, who oversee the water supply and recreation activities.
