Tate Dam, located in Arion, Iowa, is a vital water resource managed by the local government for fire protection, stock, and small fish pond purposes. Built in 1958 by the USDA NRCS, this earth dam stands at 38 feet high and spans 350 feet in length, with a storage capacity of 40 acre-feet. Situated on the TR-Boyer River, Tate Dam also serves as a critical control structure to regulate water flow in the area.

Despite its low hazard potential, Tate Dam is subject to state regulations and inspections by the Iowa Department of Natural Resources. The dam's moderate risk level is attributed to its age and the need for a condition assessment, which has not been rated yet. While the dam has not undergone recent modifications or emergency preparedness assessments, its historical significance in providing water resources for the community underscores the importance of continued monitoring and maintenance to ensure its long-term stability and functionality. As a key feature in the local water infrastructure, Tate Dam plays a crucial role in supporting the ecological and recreational needs of the surrounding area.
