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.

Natural lake levels usually move slowly, following rain, snowmelt and evaporation. A rise after a wet week can flood low docks and beaches, while late-summer lows expose rocks and weed beds near shore.

The gauge is listed by USGS as Devils Lake near Baraboo, WI. 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.
