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.
Reservoir levels are managed. Operators lower them ahead of flood season, hold them for summer recreation, and draw them down for dam work. When the lake falls well below its usual level, shallow points and stumps start showing up in places that are normally safe.
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 Lewis Smith (APC). 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.
