Harper, located in Robertson County, Tennessee, is a private earth dam constructed in 1960 on Tribbrush Creek. The dam stands at a hydraulic height of 22.5 feet and a structural height of 28.5 feet, with a length of 435 feet and a maximum storage capacity of 189 acre-feet. Although it has a low hazard potential, it is considered to have a moderate risk level, with a condition assessment that is currently not rated.

Despite its age, Harper has not undergone any modifications in recent years and has not been inspected since March 2016. The dam does not have an Emergency Action Plan (EAP) in place, and its risk management measures are currently unspecified. While it is not under federal regulation or oversight, Harper plays a crucial role in water resource management in the area, with its primary purpose and associated structures not specified. Water and climate enthusiasts may find Harper an intriguing case study for understanding the maintenance and risk assessment of private dams in the region.
