Hico is a state-regulated dam located in Henry, Tennessee, along the TRIBNORTH FORK OBION RIV. Built in 1987, this earth dam stands at a structural height of 21.4 feet and spans 855 feet in length, with a maximum storage capacity of 250 acre-feet. The dam is under the oversight of the TENNESSEE SAFE DAMS PROGRAM, ensuring that it undergoes regular inspections, with the last assessment conducted in November 2020 revealing a satisfactory condition.

Despite its moderate risk assessment of level 3, Hico poses a significant hazard potential due to its uncontrolled spillway type. The dam is not equipped with outlet gates and has no associated locks. While it has not been modified over the years, the dam's emergency action plan status, inundation maps, and risk management measures are not specified in the available data. With a designated inspection frequency of 2, Hico remains an essential structure for water resource and climate enthusiasts to monitor closely for any potential safety concerns or maintenance needs.
