About Black Horse Dam
The primary purpose of Black Horse 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 George Gary (private). It impounds the Tr-pin Oak Br near Bucklin.
The dam stands 25 feet tall, creates a reservoir covering 13 acres, has a maximum storage capacity of 174 acre-feet, and collects water from a drainage area of 260 square miles. Completed in 1974, 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.
