About Alamos Detention Dam
The primary purpose of Alamos Detention 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 Canada Alamos near Cuba, Nm.
The dam stands 28 feet tall and stretches 1,660 feet across, creates a reservoir covering 14,186 acres, has a maximum storage capacity of 570 acre-feet, and collects water from a drainage area of 41 square miles. 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. The most recent inspection on record was 08/27/2020.
