With a height of 27 feet and a length of 323 feet, this dam has a storage capacity of 63 acre-feet and serves to regulate the flow of a tributary to Soap Creek. Situated in Davis County, Iowa, Dykes Dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement.
The dam's hazard potential is rated as low, and its condition has not been assessed. Despite not having a formal Emergency Action Plan (EAP) or updated emergency contacts, Dykes Dam provides essential flood control and water resource management benefits to the surrounding area. With a spillway width of 14 feet and a surface area of 4.4 acres, this structure plays a crucial role in maintaining the stability of the local watershed and protecting downstream communities from potential flooding events.
While Dykes Dam does not fall under the jurisdiction of the US Army Corps of Engineers, it is a vital infrastructure asset for the region. As a key component in the management of water resources and climate resilience efforts, this dam reflects the collaborative efforts of private owners, regulatory agencies, and designers to ensure the safety and sustainability of the surrounding environment. Dykes Dam stands as a testament to the importance of effective dam management in safeguarding communities and natural ecosystems against the impacts of changing climate conditions.
