About Charles Mill Lake

Charles Mill Lake is a reservoir on the Black Fork Mohican River in Ohio, operated by U.S. Army Corps of Engineers. Its full summer pool sits at 997 ft above sea level. Live water levels come from the U.S. Army Corps of Engineers (CWMS) and update hourly.

Understanding Charles Mill Lake's water level

"Full pool" is the elevation U.S. Army Corps of Engineers targets when Charles Mill Lake is completely filled — 997 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 997 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 Charles Mill 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 Charles Mill 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.
