Dd No 104

About Dd No 104

The primary purpose of Dd No 104 is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Grouse-silver Creeks Wjd No 92 (local government). It impounds the Grouse Creek-tr.

The dam stands 40 feet tall and stretches 1,000 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 663 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2001, the structure is relatively new.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. 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 04/11/2023.

At 40 feet, this dam is taller than 87% of dams nationwide.
