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.

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 Lower Monumental Lock and Dam. 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.
