About Bryson

The primary purpose of Bryson 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 Northbrook Carolina Hydro Ii, Llc (private). It impounds the Oconaluftee near Ela.

The dam stands 45 feet tall and stretches 341 feet across, creates a reservoir covering 43 acres, has a maximum storage capacity of 260 acre-feet, and collects water from a drainage area of 188 square miles. Completed in 1925, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 10/19/2021.

At 45 feet, this dam is taller than 91% of dams nationwide.
