Shaw Dam, located in Oakland Mills, Iowa, is a privately owned structure designed by USDA NRCS to serve multiple purposes including fire protection, stock, and small fish pond management. Completed in 1976, this earth dam stands at a height of 27 feet and spans 350 feet in length, with a storage capacity of 53 acre-feet. While the dam is regulated and inspected by the Iowa DNR, its hazard potential is rated as low and its condition assessment is currently not rated.

Situated on the TR-Skunk River within the Rock Island District, Shaw Dam plays a vital role in water resource management for the area. With a drainage area of 0.2 square miles and a surface area of 5 acres, the dam provides essential water storage for its primary purposes. Although it operates with an uncontrolled spillway type and has a moderate risk level, the dam has not been modified in recent years and lacks certain emergency preparedness measures such as an updated emergency action plan and inundation maps.

Overall, Shaw Dam serves as a key infrastructure for water resource management in Henry County, Iowa, contributing to fire protection, livestock needs, and small-scale aquatic ecosystems. While its risk level is moderate, the dam's low hazard potential and current condition assessment indicate a stable operational status. However, improvements in emergency preparedness and ongoing risk management measures could enhance the resilience of this important water structure in the face of potential climate impacts.
