The Fish Lake Valley is a 25 mi (40 km) long endorheic valley in southwest Nevada, one of many contiguous inward-draining basins collectively called the Great Basin. The alluvial valley lies just northwest of Death Valley and borders the southeast, and central-northeast flank of the massif of the White Mountains of California. The valley's southern end lies in eastern Inyo County, California. The valley is sparsely populated with ranchers and indigenous Pauite. Business services are located in the valley's only town Dyer.
