Carlyle Lake Pool Crest Update, as of December 30, 2015

Published Dec. 30, 2015
CARLYLE LAKE - As of 11:00 a.m. on Wednesday December 30, 2015 the pool elevation at Carlyle Lake was 455.34 feet, referenced to the National Geodetic Vertical Datum (NGVD), with a release of approximately 5,000 cubic feet per second (cfs). The inflow for Tuesday December 29, 2015 was approximately 63,523 day second feet (dsf). With current precipitation on the ground, Carlyle Lake is forecasted to crest at 458.5 feet NGVD on Saturday, January 2, 2016.

Carlyle Lake Dam is operating as designed, helping reduce flood stages on the Lower Kaskaskia and Mississippi Rivers. Record precipitation and flows on downstream tributaries including Shoal Creek and Crooked Creek have resulted in high water levels downstream of Carlyle Lake.

Due to the rising water level, some breakwaters and facilities at Carlyle Lake 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.

All boat ramps will be closed except the high water ramps at Tamalco and Boulder will be available for launching. Eldon Hazlet State Park will be closed due to inundation of the entrance road.

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
