largely located in Clinton County, Illinois

The lake was created by the U.S. Army Corps of Engineers
, which built Carlyle Dam
across the Kaskaskia River
, thereby creating a reservoir filled to a mean elevation of 446 feet (136 m) above sea level. The region of Southern Illinois
where Carlyle Lake now stands is relatively flat, and the lake is relatively shallow.
As part of the lake's planning process, 600 graves were exhumed
from seven small rural cemeteries, and 69 oil wells were capped. Construction of the dam began on October 18, 1958, and the reservoir's planned expanse slowly filled with water. The lake was dedicated on June 3, 1967.

Grouped around the lake are the Dam West, Dam East, Coles Creek, Boulder and Coles Creek Recreation Areas operated by the U.S. Army Corps of Engineers and the Eldon Hazlet State Recreation Area
, South Shore State Park

operated by the Illinois Department of Natural Resources.

and being mud flats. For this reason, it is not an ideal lake for some forms of... Read More
