About Big Pike Dam
The primary purpose of Big Pike 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 Trib Indian Creek.
The dam stands 35 feet tall and stretches 363 feet across, creates a reservoir covering 10 acres, and has a maximum storage capacity of 160 acre-feet. Completed in 1965, 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 07/21/2017.
At 35 feet, this dam is taller than 82% of dams nationwide.
