Scott is a concrete dam located in Lake County, California, built in 1921. It carries a High hazard potential classification and has a fair condition assessment.

About Scott

The primary purpose of Scott 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 Pacific Gas And Electric Company (private). It impounds the Eel River near Dos Rios.

The dam stands 138 feet tall and stretches 805 feet across, creates a reservoir covering 2,280 acres, has a maximum storage capacity of 80,463 acre-feet, and collects water from a drainage area of 289 square miles. Completed in 1921, 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 06/28/2023.

At 138 feet, this dam is taller than 99% of all dams in the United States.
