About Cheng Lake Dam
The primary purpose of Cheng 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 David Cheng (private). It impounds the Tr Little Cedar Creek near Jefferson City.
The dam stands 15 feet tall, creates a reservoir covering 10 acres, has a maximum storage capacity of 80 acre-feet, and collects water from a drainage area of 190 square miles. Completed in 1971, 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.
