About Allen Dam
The primary purpose of Allen 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 Hadley Stewart (private). It impounds the Tr-west Muddy Creek near Modena.
The dam stands 25 feet tall, creates a reservoir covering 2 acres, has a maximum storage capacity of 27 acre-feet, and collects water from a drainage area of 20 square miles.
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.
