Deal Dam, located in Greene County, Iowa, is a privately owned structure designed by the USDA NRCS for fire protection, stock, and small fish pond purposes. Completed in 1965, this earth dam stands at 27 feet in height with a length of 324 feet, offering a storage capacity of 65 acre-feet. Situated on the TR-North Raccoon River, Deal Dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance with state standards.

With a low hazard potential and a moderate risk assessment rating, Deal Dam is classified as not rated in terms of its condition assessment. Despite not having an Emergency Action Plan (EAP) in place, the dam continues to serve its primary functions effectively. The structure's uncontrolled spillway type and soil foundation contribute to its overall design, while its location in the Rock Island District further highlights its importance in water resource management within the region. As a key feature in the local landscape, Deal Dam stands as a testament to the collaborative efforts of the Natural Resources Conservation Service and private owners in ensuring water security and environmental protection in Iowa.
