Walker Lake

Walker Lake is a natural lake, in the Great Basin in western Nevada in the United States. It is 11 mi long and 5 mi wide, in northwestern Mineral County along the east side of the Wassuk Range, about 75 mi southeast of Reno. The lake is fed from the north by the Walker River and has no natural outlet except absorption and evaporation. The community of Walker Lake, Nevada, is found along the southwest shore.

The lakebed is a remnant of prehistoric Lake Lahontan that covered much of northwestern Nevada during the ice age. Although the ancient history of Walker Lake has been extensively studied by researchers seeking to establish a climatic timeline for the region as part of the Yucca Mountain Nuclear Waste Repository study, this research has raised many puzzling questions.
