Ahrens Dam, located in Cass County, Nebraska, is a privately owned structure designed by the USDA NRCS and regulated by the Nebraska Department of Natural Resources. Completed in 1976, this earth dam stands at a height of 22 feet and serves multiple purposes including flood risk reduction. With a normal storage capacity of 24 acre-feet and a drainage area of 0.3 square miles, the dam plays a crucial role in managing water resources in the area.
