Background reading: Lahontan Reservoir on Wikipedia
Lahontan Reservoir covers about 9,884 acres in Churchill County, Lyon County, Nevada and is classed as a reservoir. The reservoir dates to 1905.
We read the level from USGS gauge 10312100, listed as Lahontan Reservoir near Fallon, NV. Wind and weather come from the National Weather Service grid cell over the lake, so the numbers describe open water rather than the nearest airport.
It is big enough for a proper sail but small enough that waves rarely get serious. Gusts off the shoreline are usually the bigger story than wave height. Reservoir levels move with releases and inflow, so ramps and beaches can change week to week. The water level page tracks that day by day.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
