Lake Mendocino, man-made lake in California, United States

Lake Mendocino is a large reservoir in California created by the Coyote Valley Dam, situated in the hills of the Northern Coastal Range near Ukiah. The lake spans a broad area surrounded by forest and open land, with more than 300 campsites and several recreation areas offering kayaking, fishing, swimming, and hiking.

The lake was created in 1958 when the Coyote Valley Dam was completed to control flooding and store water for surrounding communities and farms. During the Cold War, a fallout shelter was built into the dam as a precaution against nuclear threats.

The lake carries the name of the Pomo people, whose language still names some of the campsites in the area today. This connection reminds visitors of the long presence of Native Americans in this valley.

Bring sun protection, water, and sturdy shoes for your visit, as campsites fill quickly during peak seasons. Boat rentals are available on-site, and arriving early in the day helps you avoid crowds and enjoy calmer waters.

The lake is home to aggressive catfish that occasionally bite swimmers, making it an unexpected concern for water visitors. Additionally, health advisories exist regarding mercury levels in fish, which anglers should know before consuming their catch.
