Dam profile
NID height · 28 ft28 ft tall and 460 ft long, taller than 62% of U.S. dams with a recorded height. Height is drawn to scale against a two-story house, about 25 ft; the profile is a generic concrete gravity section and the water level is illustrative.
About Tatum Reservoir
The primary purpose of Tatum Reservoir 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 Unnamed.
The dam stands 28 feet tall and stretches 460 feet across, creates a reservoir covering 2 acres, and has a maximum storage capacity of 11 acre-feet. Completed in 1959, 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 04/18/2012. That was over 14 years ago.
