Ada Happel Dam, located in Cuming County, Nebraska, was completed in 1985 by the USDA NRCS and is privately owned. The dam is primarily used for flood risk reduction along the TR-Elkhorn River and has a maximum storage capacity of 119 acre-feet. With a height of 26 feet and a length of 500 feet, the earth dam is supported by buttress and stone cores, making it a significant structure in the area.

Managed by the Nebraska Department of Natural Resources, the dam is regularly inspected and regulated to ensure its structural integrity and safety. Despite being classified as having a low hazard potential, the dam's condition assessment in 2018 rated it as fair. In case of emergencies, the dam does not have an Emergency Action Plan (EAP) in place, but the inspection frequency of every 5 years helps in monitoring its overall performance and maintenance needs.

With its crucial role in flood risk reduction and water resource management in the region, Ada Happel Dam stands as a testament to effective collaboration between private owners and state agencies. Its strategic location and design contribute to the protection of surrounding areas from potential water-related disasters, making it an essential asset for both the local community and environmental enthusiasts interested in water resource conservation and climate resilience efforts.
