Lake Mendocino is a large reservoir in Mendocino County, California, northeast of Ukiah. It covers 1,922 acres (7.78 km2) and was formed by the construction of Coyote Valley Dam in 1958 (67 years ago).
The lake and dam provide flood control, water conservation, hydroelectric power, and recreation.
Lake Mendocino is administered by the U.S. Army Corps of Engineers and offers disc golf, boating, water skiing, fishing, camping, and hiking.
There are 300+ campsites plus a small number of boat-in only sites. Three groups of campsites are named in the Pomo language of the local native people. There are two boat ramps, at the north and south ends of the lake, and use for watersports is permitted.
The lake also has numerous day use and picnic areas.
Several hiking trails traverse the length of the lake.
The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for Lake Mendocino based on levels of mercury found in fish caught from this water body.
