Coming up with a plan to operate the dam was complicated. It took nearly 10 years and involved multiple stakeholders, including all of the affected communities, the Minnesota Department of Natural Resources and the U.S. Army Corps of Engineers. Using historical lake elevations, the plan was developed to mimic natural hydrologic conditions throughout the year and to account for changing weather. MCWD still uses this scientific model to manage water levels and coordinates with the National Weather Service to provide even more tailored management of the dam.

There are six management goals of the dam: reduce flooding; keep water in the creek during dry periods; enhance recreation, wildlife, and aquatic life; and improve or maintain...
