Monitoring location 10312100 is associated with a Lake, Reservoir, Impoundment in Churchill County, Nevada. Current conditions of Lake or reservoir water surface elevation above NAVD 1988 and Reservoir storage are available. Water data back to 1917 are available online.

Be advised that the stage-capacity relation used to compute Lahontan Reservoir storage from lake stage was changed effective March 25, 2020. The relation used prior to March 25, 2020 was from a bathymetric survey completed in 2004. After March 25, 2020, the relation is from a bathymetric survey completed by the Bureau of Reclamation in 2019.
