About the merced river


The Merced River is a 145-mile long river that flows through the central valley of California. The river starts in the Sierra Nevada Mountains and flows into the San Joaquin Valley. The river has played an essential role in the history of the area, with Native American tribes using it for fishing and transportation. The river has also been dammed to provide hydroelectric power and water for agriculture. The New Exchequer Dam forms Lake McClure and the New Don Pedro Dam creates Lake Don Pedro, which are both important reservoirs on the river. Recreational activities such as fishing, rafting, and camping are popular along the river, particularly in the Yosemite Valley. The river also supports agricultural uses, with irrigation from the river water used to grow crops including almonds, grapes, and walnuts.
