Boca Reservoir is located in northern California and is a popular recreation area for boating, fishing, and camping. The reservoir was created in the early 20th century to store water for irrigation and hydropower in the Truckee River Basin. The hydrology of the reservoir is heavily dependent on snowpack from the Sierra Nevada Mountains and the surrounding area. The Truckee River and Little Truckee River are the primary surface flow providers, while snowmelt runoff from the surrounding mountains also contributes to the reservoir's water supply. The area surrounding the reservoir is used for agriculture, including grazing and hay production. The recreational uses of the reservoir are numerous, including boating, fishing, swimming, and camping. The reservoir is also home to a variety of wildlife, including bald eagles, osprey, and black bears.
