Reading these numbers

This gauge reports gage height, measured against a local reference point at the station rather than sea level. The number is useful for tracking rises and drops, but it is not an elevation, so do not compare it with charts that list elevations above sea level.

Reservoir levels are managed. Operators lower them ahead of flood season, hold them for summer recreation, and draw them down for dam work. When the lake falls well below its usual level, shallow points and stumps start showing up in places that are normally safe.

High water brings its own problems: floating debris after storms, flooded docks and courtesy piers, and no-wake rules near flooded campgrounds. A quick look at the trend before you hitch up saves a wasted trip.

The gauge is about 2 miles from the center of the lake and is listed by USGS as Mud Lake near Terreton ID. Wind can pile water up at one end of a big lake for a few hours, so short spikes on a windy day are normal.
