Yadkin Narrows Bypass Spillway Control Structure

About Yadkin Narrows Bypass Spillway Control Structure

The primary purpose of Yadkin Narrows Bypass Spillway Control Structure is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Cube Yadkin Generation Llc (private). It impounds the Yadkin near River Haven.

The dam stands 88 feet tall and stretches 520 feet across, creates a reservoir covering 5,355 acres, has a maximum storage capacity of 217,080 acre-feet, and collects water from a drainage area of 4,180 square miles. Completed in 1917, the structure is over a century old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 08/20/2025.

At 88 feet, this dam is taller than 97% of all dams in the United States.
