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.

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 listed by USACE as New Hogan Lake Pool. 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.
