Carlyle Lake Pool Update

As of 3:00 p.m. on Monday, 1 April 2019 the pool elevation at Carlyle Lake was 448.95 feet, referenced to the National Geodetic Vertical Datum (NGVD). The current release rate is approximately 5,130 cubic feet per second (cfs). The inflow for Sunday, 31 March 2019 was approximately 12,820 day second feet (dsf). With current precipitation on the ground, Carlyle Lake is forecasted to crest at 450.0 feet NGVD on Thursday, 4 April 2019. In order to free up flood control storage in the lake and to continue to provide benefits to other project purposes, downstream releases will increase to approximately 10,000 cfs on Friday, 5 April 2019.

Due to the rising water level, some breakwaters and facilities will be overtopped and caution should be used when boating near these and other submerged structures. Boaters are also reminded to use caution and watch for floating logs and other debris that may be present. Some township roads around the lake will also become inundated, motorists should use caution when driving in low lying areas around the lake.

Boat ramps impacted by the high water conditions include: Dam West, Dam East, Coles Creek, Boulder, Keyesport, Peppenhorst, and Allen Branch. High water ramps at Dam West, Dam East, Coles Creek, and Boulder are available for launching.

The Corps of Engineers continues to work closely with their partners, the Carlyle Lake Association, Mid-Kaskaskia River Association and the Okaw River Basin Coalition to monitor the situation. For more information, contact the Carlyle Lake Project Office at (618) 594-2484 or email at
