Lake Drawdown Information

LAKE RED ROCK DRAWDOWN PLANNED FOR 2010

The US Army Corps of Engineers will draw down the reservoir ten feet in the fall of 2010 to dewater the tainter gate bays. The tainter gates serve as the emergency spillway for the dam and are lifted up and down by cables. During the flood of 1993, several of these cables snapped.

All the cables were replaced immediately following the flood and put on a 15-year replacement schedule. At the conservation pool elevation of 742 feet above sea level, the cable attachment brackets are permanently submerged. The lowered reservoir level will allow direct access to the
brackets.

Boat Ramp Status: As of October 2, 2010, all of the boat ramps on Lake Red Rock are closed due to drawdown impacts on ramps. This includes boat ramps at Whitebreast, South Overlook, Marina Cove, Cordova, and Elk Rock State Park. For more information, contact the Corps of Engineers office at (641) 828-7522 or (641) 628-8690.
