Cottonwood Detention Dam

About Cottonwood Detention Dam

The primary purpose of Cottonwood Detention Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Doi Blm (federal). It impounds the Tribuary To Cottenwood Creek near Parkdale.

The dam stands 36 feet tall and stretches 500 feet across, creates a reservoir covering 131 acres, and has a maximum storage capacity of 131 acre-feet. Completed in 1956, the structure is well into its service life at over 50 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 08/12/2011. That was over 14 years ago.

At 36 feet, this dam is taller than 83% of dams nationwide.
