Neenah, a privately owned dam located in Winnebago, Wisconsin, plays a crucial role in flood risk reduction along the Fox River. Built in 1881, this gravity dam stands at a height of 15 feet and spans 650 feet, providing a storage capacity of 1,100,000 acre-feet. With a normal storage capacity of 700,000 acre-feet and a drainage area of 6,124 square miles, Neenah is essential in managing water levels and mitigating potential flooding in the region.

Despite its age, Neenah remains in satisfactory condition and is inspected regularly to ensure its structural integrity and operational effectiveness. With a high hazard potential and a very high risk assessment rating, it is vital that the dam continues to be properly maintained and managed. The dam's controlled spillway, with a maximum discharge capacity of 24,000 cubic feet per second, further enhances its flood risk reduction capabilities, safeguarding the surrounding communities and infrastructure from potential water-related disasters.

Neenah not only serves as a critical infrastructure for flood control but also offers recreational opportunities for the local community. As one of the key structures managed by the Wisconsin Department of Natural Resources (WIDNR), Neenah stands as a testament to effective water resource management and climate resilience efforts in the region, highlighting the importance of sustainable practices in safeguarding our water resources for future generations.
