Outflows at Lake Red Rock have been reduced several times lately to mitigate the potential for flooding down stream and now outflows are being increased as the reservoir fills up in order to maintain flood storage capacity.
The US Army Corps of Engineers is encouraging residents in flood prone areas downstream on the Des Moines River to prepare for higher river levels. The river is currently 2 feet below its flood stage of 14 feet near Tracy.
Currently, the lake is at 775 feet and outflows volume is 35,000 cubic feet per second. The record high stage at Red Rock is 782.67 feet, set in July of 1993.
