About Mud Lake

Mud Lake is a 3,118-acre reservoir in Jefferson County, Idaho. The water surface sits about 4,783 ft above sea level.

We read the level from USGS gauge 13115000, listed as Mud Lake near Terreton ID. 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.
