Historically, it was used by Native Americans for fishing and hunting, and later by gold miners during the California Gold Rush. The river's hydrology is largely dependent on snowmelt, with peak flows occurring in the spring and early summer. The river is regulated by several reservoirs and dams, including the Pardee and Camanche Reservoirs, which are used for flood control, hydroelectric power generation, and water supply. The Mokelumne River also provides important agricultural water to the Central Valley. Recreational activities like fishing, kayaking, and hiking are popular along its banks. The river is also a major source of drinking water for the East Bay Municipal Utility District.
