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.
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 Marion Lake. 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.
