Tweedy Dam, located in Van Meter, Iowa, along the TR- South Raccoon River, is a private earth dam designed by the USDA NRCS in 1982 for fire protection, stock, or small fish pond purposes. With a height of 32 feet and a length of 231 feet, the dam has a storage capacity of 23 acre-feet and serves as a water resource for the local area. The dam is regulated by the Iowa Department of Natural Resources and is inspected, permitted, and enforced by state authorities to ensure its safe operation.

Despite its low hazard potential and moderate risk assessment, Tweedy Dam has not been rated for its condition. The dam does not have a designated Emergency Action Plan (EAP) or updated inundation maps, but it meets state guidelines and has emergency contacts on file. The risk management measures for the dam are not specified, but the dam remains an important structure for water resource management and climate enthusiasts in the area. With its unique design and purpose, Tweedy Dam stands as a testament to the importance of sustainable water management practices in Iowa.
