About Byron Simpson Lake Dam
The primary purpose of Byron Simpson 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 Byron Simpson (private). It impounds the Tr-kettle Creek near Nettleton.
The dam stands 20 feet tall, creates a reservoir covering 8 acres, has a maximum storage capacity of 86 acre-feet, and collects water from a drainage area of 115 square miles. Completed in 1950, the structure is well-established, with more than 75 years of service.
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.
