Thermalito Total is a series of reservoirs and canals located in Butte County, California. These reservoirs were built in the early 20th century as part of a larger irrigation system designed to provide water to agricultural lands in the area. The hydrology of the area is characterized by a mix of surface flow and snowpack, with the Oroville Dam serving as the primary provider of surface flow. The snowpack in the Sierra Nevada Mountains also contributes to the water supply, with runoff from these mountains feeding into the Feather River. In addition to agricultural uses, Thermalito Total also provides recreational opportunities for fishing and boating. However, the area is prone to drought, and water management has become an important issue in recent years.
