Trinity Lake is a reservoir located in Trinity County, California, formed by the Trinity Dam on the Trinity River. The lake was created in 1961 as part of the Central Valley Project, a federal water management project. The lake's hydrology is regulated by the dam and the Trinity River, which provides the lake with water from snowpack and rainfall in the surrounding mountains. The lake serves as a source of irrigation water for agriculture in the surrounding areas, as well as a popular destination for recreational activities such as fishing, boating, and camping. The lake's surface flow is also important for downstream water users, including several Native American tribes that rely on the Trinity River for their livelihoods. Despite concerns over drought and water management in California, the lake remains an important resource for the region.
