About Lynx Dam
The primary purpose of Lynx 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 Lynx Draw.
The dam stands 31 feet tall and stretches 439 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 17 acre-feet, and collects water from a drainage area of 3 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. Its condition is rated unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. The most recent inspection on record was 07/20/2017.
