Reading these numbers

Readings are elevations in feet above the North American Vertical Datum of 1988 (NAVD88), the current national reference. Older dam documents often quote NGVD29 instead, which can differ by a few feet. See NGVD29 vs NAVD88.

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 about 1 miles from the center of the lake and is listed by USGS as Lake St. Helen at St. Helen, MI. 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.
