About Six & Fifty Detention Dam
The primary purpose of Six & Fifty 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 Tributary Of West Salt Creek.
The dam stands 20 feet tall and stretches 489 feet across, creates a reservoir covering 159 acres, and has a maximum storage capacity of 201 acre-feet. Completed in 1957, 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 05/05/2011. That was over 14 years ago.
