Reading these numbers

Readings are reservoir surface elevations in feet, as published by the U.S. Army Corps of Engineers. Compare them with ramp and dock elevations from the lake operator to judge whether a launch is usable.

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 about 1 miles from the center of the lake and is listed by USACE as DELAWARE LAKE AT DELAWARE. 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.
