About Nageezi Dam
The primary purpose of Nageezi Dam is debris control. The dam is designed to catch sediment, rocks, and debris carried by flowing water — particularly important in areas prone to mudslides or heavy erosion. The dam is owned by Doi Blm (federal). It impounds the Blanco Wash near Nageezi.
The dam stands 23 feet tall and stretches 1,280 feet across, creates a reservoir covering 22 acres, and has a maximum storage capacity of 82 acre-feet. Completed in 1954, 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. The most recent inspection on record was 06/09/2020.
