Mule Creek Watershed Sta 30+00, located in Mills County, Iowa, is a key water resource management structure designed by the USDA NRCS to serve multiple purposes including fire protection, stock, and small fish pond management. Completed in 1955, this earth dam stands at 35 feet in height and spans 537 feet in length, with a storage capacity of 42 acre-feet and a surface area of 2.3 acres. The dam plays a crucial role in flood risk reduction for the TR-Mule Creek river system, which covers a drainage area of 0.31 square miles.

Managed by the local government and regulated by the Iowa Department of Natural Resources, Mule Creek Watershed Sta 30+00 is deemed to have a low hazard potential and a moderate risk assessment rating. Despite not having a current condition assessment, the dam is operational and meets regulatory standards for state permitting, inspection, and enforcement. The structure's emergency action plan status, inundation maps, and risk management measures remain unspecified, suggesting potential areas for improvement in emergency preparedness and response. Enthusiasts of water resources and climate management in the region may find Mule Creek Watershed Sta 30+00 to be a fascinating case study in multi-purpose dam infrastructure in rural Iowa.
