Tulare Lake, named
Laguna de Tache by the Spanish, is a freshwater
dry lake with residual
wetlands and
marshes in the southern
San Joaquin Valley,
California,
United States. After
Lake Cahuilla disappeared in the 17th century, Tulare Lake was the largest freshwater lake west of the Mississippi River and the second-largest freshwater lake entirely in the United States (excluding the Great Lakes which share area with Canada), based upon surface area. The lake dried up after its tributary rivers were diverted for agricultural irrigation and municipal water uses.
