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.

On a reservoir, a few feet of drop changes the shoreline more than you would think. Low water exposes stumps, sandbars and old roadbeds that are normally well under the hull, and some ramps end before the water does.

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 5 miles from the center of the lake and is listed by USGS as Lake Marion near Pineville, SC. 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.
