Ball Dam, located in Louisa, Iowa, along the TR-Iowa River, was completed in 1985 by the USDA NRCS and serves multiple purposes including fire protection, stock, and small fish pond. This private dam, with a height of 29 feet and a length of 200 feet, has a storage capacity of 22 acre-feet and covers a surface area of 2 acres. While the dam is classified as having a low hazard potential, it is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance.

The dam's design, primarily consisting of earth materials and a soil foundation, contributes to its structural integrity. Despite being uncontrolled, the dam's spillway type and width are designed to manage any excess water flow effectively. Although the dam's risk assessment is moderate, it has not been rated for its condition assessment. Emergency action plans and risk management measures are currently not documented for Ball Dam, highlighting the need for continued monitoring and assessment to mitigate any potential risks or hazards associated with the structure.

Ball Dam's location in Wapello, Iowa, under the ownership of a private entity, underscores the importance of collaboration between state and federal agencies for effective regulation and enforcement. With its role in water resource management and climate adaptation efforts, the dam serves as a vital infrastructure for the local community while also posing challenges that require ongoing attention and maintenance to ensure its long-term functionality and safety.
