Patoka Lake Reservoir climbs to 101 percent full

Louisville, Ky. – Heavy rains during the past 24 hours have caused Patoka Lake Reservoir, DuBois County, Ind. to reach a record high pool of 548.12 or 101 percent full at 8 a.m. today.   The dam is structurally sound. 

As part of the projects water control plan, gate operations have been initiated.  Releases through the emergency spillway are occurring.  The U.S. Army Corps of Engineers is currently releasing 456 cubic feet per second through the gate and will add approximately 200 CFS every hour until combined outflow reaches 1,200 CFS and the pool stabilizes or reaches 549.5 feet.  These releases are part of the original project design and lake management.

Residents in Jasper can expect to see an increase of no more than two additional feet at the Jasper gage.  This estimate is highly dependent on local runoff downstream at Patoka Lake Dam.  Residents downstream from Jasper (Winslow and Patoka) will also be impacted as the level of Patoka River rises.

Patoka Lake is part of an overall system of reservoirs managed by the U.S. Army Corps of Engineers.  The system is designed to minimize flood damages by storing water caused by heavy rains until the rivers and streams are at levels that releases from the reservoirs will not cause additional flooding downstream.
 
The spillway is designed to provide a safe path for the excess flows. Then, water from the spillway re-enters downstream of the dam. Water releases are managed by Corps’ hydrology and hydraulics departments in concert with other government agencies.

The Corps coordinates with local, state and other emergency management agencies and officials to share information on current conditions at its reservoirs.
