The existing ponding basin (and dam) in Hansen Park was originally constructed in 1969 to be 4 feet deep. Following years of sedimentation, the pond depth was only 6 inches deep just before the project. RCWD worked closely with the Minnesota DNR, U.S. Army Corps of Engineers, and Minnesota Board of Water and Soil Resources (BWSR) to implement the removal of the dam and excavation of the pond. The pond depth when complete will again be an average of 4 feet deep. However, the normal water level will be lowered 2 feet and the dam was raised 2 feet. This combination allows for an additional 11.6 million gallons of water to be stored in the park during heavy storms.
