Piedmont is a private irrigation dam located in Uinta, Wyoming, along the Big Muddy Creek. Built in 1902, this earth dam stands at 34 feet tall and stretches 549 feet in length, providing storage capacity of 840 acre-feet for irrigation purposes. Despite its age, Piedmont has a low hazard potential and is currently rated in poor condition, with the last inspection conducted in September 2019.

The dam features an uncontrolled spillway with a width of 30 feet and outlet gates that include uncontrolled and valve mechanisms. While the risk assessment categorizes Piedmont as having a moderate risk level, it does not have an Emergency Action Plan (EAP) in place or updated inundation maps. The surrounding area is sparsely populated, helping to mitigate the potential impact of any dam failure. Overall, Piedmont serves as a critical water resource for agriculture in the region, but ongoing maintenance and monitoring are necessary to ensure its continued safety and functionality.
