Arnold-Armstrong Subwatershed Station 69+48, located in Monona, Iowa, is a vital water resource managed by the local government for fire protection, livestock use, and as a small fish pond. This earth dam, constructed in 1963 by the USDA NRCS, stands at a height of 49 feet and has a storage capacity of 149 acre-feet. With a drainage area of 1.01 square miles and a surface area of 5.6 acres, the dam plays a crucial role in flood risk reduction in the region.

Managed by the Iowa Department of Natural Resources, this dam on Dutch Creek is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. Despite its low hazard potential, the dam's condition assessment is currently not rated. With a moderate risk level assigned, there is a need for ongoing risk management measures to safeguard the surrounding community and environment. As a part of the Rock Island District, this structure contributes to water resource management and climate resilience efforts in the area.

In the event of an emergency, the presence of an Emergency Action Plan (EAP) and updated contact information is crucial for effective response and risk mitigation. While the dam's EAP status and adherence to guidelines are not specified in the data, ensuring that these components are in place is essential for the overall safety and resilience of the Arnold-Armstrong Subwatershed Station 69+48. As water resource and climate enthusiasts, staying informed and advocating for proper maintenance and management of such structures is key to preserving the integrity of our natural ecosystems.
