Enl. Eddie, located in Sheridan, Wyoming, is a privately owned earth dam designed by HUGH LOWHAM and completed in 1953 for flood risk reduction along the Rye Draw river. With a dam height of 30 feet and a hydraulic height of 21 feet, this structure serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. The dam has a storage capacity of 68 acre-feet and covers a surface area of 3 acres, with a drainage area of 0.14 square miles.

Despite its low hazard potential and fair condition assessment, Enl. Eddie is regulated by the Wyoming State Engineer's Office (SEO) with state jurisdiction, permitting, inspection, and enforcement in place. The dam features an uncontrolled spillway and one uncontrolled outlet gate. While the risk assessment indicates a moderate risk level, the dam has not undergone recent risk management measures or updates to its emergency action plan. Liz Cheney (R) represents the area in the US Congress, but the dam is not under the jurisdiction of the US Army Corps of Engineers.

Water resource and climate enthusiasts will find Enl. Eddie an interesting case study in dam infrastructure, highlighting the importance of private ownership in maintaining flood risk reduction structures. The dam's historical significance, combined with its multiple purposes and state-regulated status, offer a unique perspective on water management in the region. With its moderate risk level and fair condition, there may be opportunities for further assessment and potential improvements to ensure the long-term safety and effectiveness of Enl. Eddie in mitigating flood risks along the Rye Draw river.
