Located in Ringgold County, Iowa, the East Fork Grand River Watershed Site A-122 is a local government-owned structure designed by the USDA NRCS to address flood risk reduction in the area. Completed in 2010, this earth dam stands at a height of 26 feet and spans a length of 550 feet, with a storage capacity of 64 acre-feet. The primary purpose of the dam is flood risk reduction, but it also serves other functions such as fish and wildlife pond creation, grade stabilization, and recreation.

With a low hazard potential and a not yet rated condition assessment, the East Fork Grand River Watershed Site A-122 remains a vital component of water resource management in the region. The dam's location on a tributary to the East Fork Grand River ensures that it plays a crucial role in regulating water flow and mitigating potential flood risks. Despite being state-regulated and inspected, the dam has not been assigned a risk assessment or management measures, highlighting the need for ongoing monitoring and maintenance to ensure its continued effectiveness in protecting the surrounding community from flooding events.
