Talmage Hill Dam, located in Grand River, Iowa, is a local government-owned structure with a primary purpose of recreation. Built in 1985 by the Soil Conservation Service (SCS), this earth dam stands at a height of 25 feet and stretches 400 feet in length. Situated on the TR-Thompson River, it serves as a recreational spot for residents and visitors alike, offering a surface area of 7 acres and a maximum storage capacity of 123 acre-feet.

Despite being classified as having a low hazard potential, Talmage Hill Dam is regulated and inspected by the Iowa Department of Natural Resources (DNR) to ensure its safe operation. The dam has a moderate risk assessment rating of 3, indicating a need for ongoing risk management measures. While the last inspection took place in 1995, the condition of the dam is currently listed as "Not Rated," highlighting the importance of regular assessments and maintenance to prevent any potential hazards.

In the event of an emergency, the dam's Emergency Action Plan (EAP) status is unspecified, calling attention to the need for updated emergency contacts and preparedness guidelines. With its serene location and vital role in water resource management, Talmage Hill Dam stands as a reminder of the intersection between human recreation and environmental stewardship in the face of changing climate conditions.
