Harmon Farms Dam, located in Braddyville, Iowa, was completed in 1996 by the USDA NRCS and serves multiple purposes, including fire protection and providing a water source for stock or small fish ponds. The earth dam stands at a height of 34 feet and has a length of 278 feet, with a storage capacity of 21 acre-feet. Situated on TR-Long Branch, the dam is regulated by the Iowa DNR and is subject to state permitting, inspection, and enforcement.

Despite its low hazard potential, Harmon Farms Dam has a moderate risk rating of 3, indicating a need for ongoing risk management measures. The dam currently has an uncontrolled spillway and is not rated for its condition assessment. While there are no associated structures or outlet gates, the dam is monitored by the Natural Resources Conservation Service and falls under private ownership. With a drainage area of 0.15 square miles, the dam's surface area is 1 acre, making it a vital resource for the surrounding area.

In the event of an emergency, the dam's Emergency Action Plan (EAP) status is currently unknown, and it has not been assessed for compliance with guidelines. With its critical role in providing water resources and supporting local agriculture, Harmon Farms Dam stands as a testament to the importance of sustainable dam management in the face of climate change and increasing water scarcity challenges.
