Grouse Creek North

About Grouse Creek North

The primary purpose of Grouse Creek North is tailings. Tailings dams contain waste material from mining operations — typically a slurry of finely ground rock left over after valuable minerals have been extracted. These structures require ongoing monitoring because tailings can contain heavy metals and other contaminants. The dam is private-owned. It impounds the Unnamed Stream Jordan Creek near Clayton.

The dam stands 110 feet tall and stretches 1,000 feet across, creates a reservoir covering 135 acres, has a storage capacity of 152 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1994, the structure is 32 years old.

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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 07/02/2013. That was over 12 years ago.

At 110 feet, this dam is taller than 98% of all dams in the United States.
