Water level history
About Delaware Lake
Delaware Lake is a reservoir on the Olentangy River in Ohio, operated by U.S. Army Corps of Engineers. Its full summer pool sits at 915 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.
Understanding Delaware Lake's water level
"Full pool" is the elevation U.S. Army Corps of Engineers targets when Delaware Lake is completely filled — 915 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 915 ft for long. A reading a few feet under full is usually just the normal operating band rather than a sign of drought.
In a normal year Delaware Lake sits highest through the summer recreation season and lower over winter, when the Corps makes room for storms. Extended dry spells in late summer and fall are what usually pull the lake noticeably below full pool.
The recent high and low above are drawn from the published history available for Delaware 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.
