Cohrs Dam in Iowa, managed by a private owner, was completed in 2011 and primarily serves to reduce flood risks in the area. Designed by USDA NRCS, the earth dam stands at a height of 36 feet and stretches 600 feet in length. It has a storage capacity of 66 acre-feet and covers a surface area of 4 acres, with a drainage area of 0.24 square miles. The dam is situated in Harrison County, near the city of Missouri Valley, and is regulated and inspected by the Iowa Department of Natural Resources.

The dam also serves secondary purposes such as creating a fish and wildlife pond, stabilizing grades, and providing recreational opportunities. Despite its low hazard potential, the dam's condition has not been rated, and emergency action plans have not been prepared. The spillway width is 20 feet and there are no outlet gates associated with the structure. Overall, Cohrs Dam plays a crucial role in managing water resources and protecting the local community from potential flooding events while also supporting environmental conservation and recreational activities in the area.
