Walker Dam, located in Louisa, Iowa, is a privately owned structure completed in 1984 with a primary purpose of fire protection, stock, or small fish pond. The dam, designed by SCS, is classified as an earth dam with a height of 31 feet and a length of 200 feet. It has a normal storage capacity of 30 acre-feet and a maximum storage of 50 acre-feet, serving the Iowa River and TR-ROFF CR. The dam is regulated by the Iowa Department of Natural Resources and is inspected, permitted, and enforced by state authorities.

Despite its low hazard potential, Walker Dam poses a moderate risk level of 3 due to its condition assessment being labeled as "Not Rated." The dam does not have an emergency action plan in place or updated inundation maps prepared. It is not under the jurisdiction of the US Army Corps of Engineers and does not have any associated federal agencies for funding, construction, or operation. The structure is in need of further risk assessment and management measures to ensure the safety of the surrounding area and water resources.

For water resource and climate enthusiasts, Walker Dam serves as a vital infrastructure for fire protection and wildlife habitat in Louisa County, Iowa. Its presence contributes to the local ecosystem and provides essential water storage for agricultural and environmental purposes. However, with the risk level considered moderate and the condition assessment not rated, there is a pressing need for enhanced monitoring, maintenance, and emergency preparedness to mitigate potential hazards and ensure the long-term sustainability of the dam and its surrounding areas.
