About Parsons Lake Dam
The primary purpose of Parsons Lake 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 Richard P Parsons (private). It impounds the Tr-missouri River near New Haven.
The dam stands 30 feet tall, creates a reservoir covering 3 acres, has a maximum storage capacity of 48 acre-feet, and collects water from a drainage area of 80 square miles. Completed in 1976, the structure is 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.
