Upstream work at hydroelectric plant temporarily suspended

Work on the upstream side of the Red Rock Dam at the hydroelectric project will be temporarily suspended as water levels are expected to rise to an elevation of 764 feet by Christmas Day.

The U.S. Army Corps of Engineers (USACE) recently announced that it expects the rise in water levels following heavy rains that dumped three inches in much of the Red Rock Dam drainage basin over a two-day period Dec. 12 and 13. The dam is located on the Des Moines River near Pella, Iowa. 

Work has been under way at the 750-foot elevation on the upstream side of the dam as crews prepare the site to build an intake structure for the hydroelectric plant that will be operated by Missouri River Energy Services (MRES) of Sioux Falls, S.D.  

Crews have demobilized, moving equipment and materials to higher ground, in preparation for the anticipated high water levels. All upstream work will be temporarily suspended until water levels return to normal. Work is continuing as usual on the downstream side of the dam.
