Located in Carroll, Tennessee, the Higdon dam stands as a testament to human ingenuity and environmental stewardship. Built in 1979, this earth dam spans 650 feet and rises to a structural height of 33.9 feet, with a hydraulic height of 30.3 feet. The dam's primary purpose is to regulate the flow of Cotton Creek, providing crucial water resource management for the region. With a normal storage capacity of 259 acre-feet and a maximum storage of 339 acre-feet, Higdon plays a vital role in flood control and water supply for the surrounding area.

Managed by the Tennessee Safe Dams Program, Higdon is subject to regular inspections and regulatory oversight to ensure its structural integrity and safety. Despite its low hazard potential and satisfactory condition assessment, the dam is classified as having a moderate risk level. This designation underscores the importance of ongoing risk management measures and emergency preparedness to mitigate potential threats and safeguard the local community. As climate change continues to impact water resources and infrastructure, the role of dams like Higdon in sustainable water management becomes increasingly significant.

With its uncontrolled spillway and minimal associated structures, Higdon exemplifies the balance between human development and environmental conservation. As the Nashville District oversees its operations and maintenance, Higdon serves as a model for effective dam management in the face of changing environmental conditions and growing water resource challenges. Whether it's regulating water flow, storing vital supplies, or protecting against potential hazards, Higdon stands as a resilient and essential element of Tennessee's water infrastructure, embodying the intersection of human innovation and natural resource conservation.
