Iowa Noname17 is a privately owned dam located in Hardin County, Iowa, designed by the USDA NRCS and regulated by the Iowa DNR. Completed in 1965, this earthen dam stands at a height of 32 feet and spans 730 feet in length, creating a storage capacity of 92 acre-feet with a normal storage level of 65 acre-feet. The dam serves primarily for recreation purposes on the TR-Iowa River, with a surface area of 8.9 acres and a drainage area of 1.15 square miles.

Despite its low hazard potential and moderate risk assessment, Iowa Noname17 is not currently rated for its condition and lacks essential emergency preparedness measures such as an Emergency Action Plan (EAP) and updated contact information. The dam features an uncontrolled spillway type and is situated in an area with limited risk management measures in place. With its picturesque location in Steamboat Rock, this dam presents both recreational opportunities and potential risks that warrant further inspection and maintenance to ensure the safety of the surrounding community and environment.
