Loud
Loud is a gravity dam located in Iosco County, Michigan, built in 1913. It carries a High hazard potential classification and has a fair condition assessment.
About Loud
The primary purpose of Loud 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 Consumers Energy Company (public utility). It impounds the Au Sable River near Oscoda.
The dam stands 40 feet tall and stretches 2,180 feet across, creates a reservoir covering 790 acres, has a maximum storage capacity of 12,600 acre-feet, and collects water from a drainage area of 1,602 square miles. Completed in 1913, 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 09/13/2022.
At 40 feet, this dam is taller than 87% of dams nationwide.
