Coyote

About Coyote

The primary purpose of Coyote 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 owned by Utah Int. Inc. (private). It impounds the Deacon Gulch near Hayden.

The dam stands 66 feet tall and stretches 900 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 192 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1977, the structure is 49 years old.

This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. The most recent inspection on record was 01/01/1999. That was over 27 years ago.

At 66 feet, this dam is taller than 96% of all dams in the United States.
