Reading these numbers
Readings are elevations in feet above the National Geodetic Vertical Datum of 1929 (NGVD29), the reference most older dam and lake charts use. If you compare with a newer chart in NAVD88, expect a difference of a few feet. Our glossary explains 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 Marion near Haines City, FL. 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.
