About Cooper Lake (Jim Chapman Lake)
Cooper Lake (Jim Chapman Lake) is a reservoir on the South Sulphur River in Texas, operated by U.S. Army Corps of Engineers. It's a top trophy-bass lake in northeast Texas. Its full summer pool sits at 440 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Cooper Lake (Jim Chapman Lake)'s water level
"Full pool" is the elevation U.S. Army Corps of Engineers targets when Cooper Lake (Jim Chapman Lake) is completely filled — 440 feet above sea level. Above that line the Corps deliberately keeps empty "flood storage" to absorb heavy rain, so the lake rarely sits far above 440 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
Cooper Lake (Jim Chapman Lake) is held near its conservation pool, with extra room above kept open for floods. In practice the larger swings come from Texas weather — levels slide through hot, dry summers and rebound when spring storms or tropical systems deliver heavy rain.
The recent high and low above are drawn from the published history available for Cooper Lake (Jim Chapman Lake), so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
