Brookville dam operating as intended, providing flood damage reduction

The U.S. Army Corps of Engineers Louisville District is closely monitoring Brookville Lake following significant rainfall across the watershed over the past 48 hours.

Brookville Lake still has available flood storage capacity to manage additional runoff and reduce downstream flooding risk. The dam is operating as designed and there are currently no dam safety concerns. Louisville District staff are onsite conducting daily inspections and monitoring conditions. This reservoir is part of a broader system managed by USACE, designed to temporarily store excess water from heavy rainfall until river and stream levels recede, preventing further downstream flooding.

As of Aug. 13, at 6 a.m., Brookville Lake's elevation was 757.52 feet. As of this morning, the pool is estimated to peak around 761 feet based on rainfall that has already occurred and potentially increasing outflows over the weekend. The additional 1-1.75 inches of rainfall forecasted across the watershed from today through Sunday could impact USACE’s ability to increase outflows and the estimated peak elevation.

In accordance with the approved water control manual, USACE will maintain releases of approximately 100 cubic feet per second (cfs) while downstream river levels remain elevated. Based on current NOAA forecasts, the river downstream of the dam is expected to peak and begin falling overnight. After downstream river levels recede, flood storage will be released. Those releases will be closely monitored, and if downstream conditions change, releases will be reduced to store additional flood water.

USACE will continue to closely monitor the lake, dam and downstream conditions and provide updates via the Brookville Lake Facebook page if anything changes.

USACE reminds the public to stay vigilant and prepared, as conditions can change rapidly. Resources for flood preparedness can be found at www.ready.gov/floods.
