What the number means
Lake levels are feet above sea level, measured at the dam. Grand Lake sits behind Pensacola Dam on the Grand (Neosho) River, near Grove and Langley, Oklahoma.
A lake a few feet under normal pool is common in fall and winter. It shows up first at boat ramps with short concrete, in the shallow backs of coves, and at docks close to shore, so look at the ramp before you back the trailer down.
When the lake rises above normal pool, the extra water is flood storage. The Corps lets it out through the dam over days or weeks, so the river below the dam can run high long after the rain stops.
