Tulare Lake or Tache Lake is a freshwater lake in the southern San Joaquin Valley, California, United States.
Historically, Tulare Lake was once the largest freshwater lake west of the Mississippi River in surface area. For thousands of years, from the Paleolithic onward, Tulare Lake was a uniquely rich area, which supported perhaps the largest population of Native Americans north of present-day Mexico.
In the second half of the 19th century, Tulare Lake was dried up by diverting its tributary rivers for agricultural irrigation and municipal water uses.
In modern times, it is usually a dry lake with residual wetlands and marshes.
The lake reappears during unusually high levels of rainfall or snow melt as it did in 1942, 1969, 1983, 1997, 1998, and 2023.
Primary inflows are Kaweah River, Kern River, Kings River, Tule River and White River.
