McHugh Dam, located in Monona County, Iowa, is a privately owned structure designed by the USDA NRCS and completed in 2011. This earth dam stands at a height of 31 feet and stretches 520 feet in length, with a storage capacity of 59 acre-feet. The primary purpose of McHugh Dam is flood risk reduction, but it also serves other purposes such as fish and wildlife pond, grade stabilization, and recreation.

Situated on a tributary to Willow Creek, McHugh Dam is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement. With a low hazard potential and a condition assessment of "Not Rated," McHugh Dam has not been assigned an Emergency Action Plan (EAP) or undergone risk assessment and management measures. Despite its modest surface area of 3 acres and drainage area of 0.22 square miles, McHugh Dam plays a crucial role in protecting the surrounding area from potential flooding events.

Owned by a private entity, McHugh Dam contributes to the conservation and management of water resources in the region while offering recreational opportunities for the local community. With its strategic location in Missouri Valley and its key role in flood risk reduction, McHugh Dam stands as a testament to the importance of sustainable water infrastructure in mitigating the impacts of climate change and ensuring the resilience of communities against natural disasters.
