Walnut Creek Duck Marsh Dam, located in Ringgold County, Iowa, is a state-regulated structure designed by the Iowa Conservation Commission for recreational purposes. Completed in 1959, this earth dam stands at a height of 8 feet and spans a length of 3925 feet, with a storage capacity of 589 acre-feet. Situated on the TR-Walnut Creek, this dam serves as a vital resource for water storage and recreational activities in the area.

Despite being classified as having a low hazard potential and a moderate risk assessment, the condition of Walnut Creek Duck Marsh Dam has not been rated. The dam has not undergone inspection since November 1960, and there is no information available on emergency action plans or risk management measures. With its uncontrolled spillway and soil foundation, the dam's structural integrity and maintenance protocols may warrant further evaluation to ensure the safety and sustainability of the surrounding environment and communities.

As a critical infrastructure in the region, Walnut Creek Duck Marsh Dam plays a crucial role in water resource management and climate resilience efforts. With its proximity to Isadora, MO, and the oversight of the Iowa Department of Natural Resources, this dam serves as a reminder of the importance of regular inspections, maintenance, and emergency preparedness to safeguard against potential risks and ensure the long-term sustainability of water resources in the area.
