Hammer Dam, located in Norwalk, Iowa, is a privately owned structure designed by NRCS for fire protection and stock purposes. Completed in 2000, this earth dam stands at a height of 28 feet and stretches 370 feet in length. The dam has a storage capacity of 17 acre-feet and covers a surface area of 1.1 acres, serving the surrounding area with a low hazard potential.

Managed by the Iowa Department of Natural Resources, Hammer Dam is regulated, permitted, inspected, and enforced to ensure its safety and functionality. The dam is situated on TR-Middle Creek and is used for fire protection, stock, or small fish pond purposes.
