Indian Valley Reservoir is a human-made lake in Lake County, California, 27 miles (43 km) west of Williams, United States, near State Route 20.
The 301,000 acre⋅ft (371,000,000 m3) capacity reservoir was created by the construction of the Indian Valley Dam across the north fork of Cache Creek in 1975 (50 years ago). The 965 ft (294 m) long and 201 ft (61 m) high earth-fill dam was built for water storage, irrigation and flood control. Although the reservoir is in Lake County, it was built by neighboring Yolo County, which owns all water rights to the 300,600 acre-feet (370,800,000 m3) of water. The dam includes a hydroelectric plant.
