About Perkins West Lake Dam
The primary purpose of Perkins West 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 Virgil H. Perkins (private). It impounds the Tr to Tyrey Creek near Morse Mill.
The dam stands 28 feet tall, creates a reservoir covering 4 acres, has a maximum storage capacity of 60 acre-feet, and collects water from a drainage area of 60 square miles. Completed in 1970, 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.
