Nelson Detention Dam, located in Washington County, Nebraska, is a vital infrastructure designed by the USDA NRCS to mitigate flood risks along Turkey Creek. Completed in 1957, this earth dam stands at a height of 50 feet and stretches 282 feet in length, providing a storage capacity of 111 acre-feet. Despite its significant hazard potential, the dam's condition assessment in 2020 revealed poor structural integrity, highlighting the need for timely maintenance and risk management measures.

Owned privately, Nelson Detention Dam falls under the regulatory oversight of the Nebraska Department of Natural Resources, with state-mandated inspections and enforcement mechanisms in place. The dam's primary purpose is flood risk reduction, serving the local community by protecting against potential inundation events. However, its outdated design and poor condition underscore the importance of regular monitoring and investment in infrastructure resilience to safeguard water resources in the region.

As climate change continues to impact precipitation patterns and intensify extreme weather events, infrastructure like Nelson Detention Dam plays a crucial role in water resource management and climate adaptation efforts. With a drainage area of 0.8 square miles and a maximum discharge capacity of 645 cubic feet per second, this dam serves as a critical line of defense against flooding in the area. Moving forward, proactive maintenance, risk assessment, and emergency preparedness will be essential to ensure the long-term effectiveness and safety of Nelson Detention Dam in the face of evolving climate challenges.
