Mckinnon, located in Marshall County, Tennessee, is a privately owned Earth dam constructed in 1973 by the USDA NRCS for the primary purpose of creating a Fish and Wildlife Pond. With a hydraulic height of 19 feet and a structural height of 25 feet, the dam stands along the East Fork Bradshaw Creek. It has a storage capacity of 55 acre-feet, with a normal storage level of 30 acre-feet, covering a surface area of 4 acres and draining a small 0.1 square mile watershed.

Despite being deemed as having a significant hazard potential, the dam's condition assessment is currently not rated, and its last inspection was conducted in September 2017. Although the dam is not state-regulated or permitted, it falls under the jurisdiction of the Tennessee state and is not subject to regular inspections, enforcement, or permitting. The spillway type for Mckinnon is listed as "Uncontrolled," and it has no outlet gates or associated locks.

For water resource and climate enthusiasts, Mckinnon presents an intriguing case study in dam management and risk assessment. With its moderate risk level and lack of formal emergency action plan, there is a need for continued monitoring and evaluation to ensure the safety and integrity of the structure. As a critical habitat for fish and wildlife, as well as a recreational area, Mckinnon serves as a reminder of the importance of sustainable water resource management practices in the face of changing climate conditions.
