Des Moines River Water Control Plan Update

The U.S. Army Corps of Engineers (USACE), Rock Island District is proposing to update the Des Moines River Regulation Manual which would include the Water Control Manual for both Saylorville Lake and Lake Red Rock. The District proposed a reservoir study incorporating Saylorville, Red Rock and Coralville Reservoirs in July 2010. The results of the 2010 Des Moines River Regulated Flow Frequency Study demonstrated a need to expand the study scope to include Southeast Des Moines and Des Moines levee systems for Flood Risk Management in Des Moines, Iowa. The updated scope of the project consists of facilitating all steps required to reevaluate and update the regulation manuals for Lake Red Rock and Saylorville Lake on the Des Moines River.  

Water control manuals provide guidance for direction, operation and management of water storage for each individual project or system of projects. USACE prepares water control manuals in the early stages of each project and periodically updates the manuals in order to keep abreast of changing conditions, legislation and other relevant factors. Water control plans are contained within water control manuals for all projects under the supervision of the United States Corps of Engineers. The plans’ primary goal is to define normal operation of a water control structure. Water control plans ensure the operations of reservoirs and locks and dams conform to legislation, laws and applicable USACE rules. Water control plans are reviewed and revised every 10 years, at a minimum.
