About Henderson Lake
The primary purpose of Henderson Lake 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 Frederick Henderson (private). It impounds the Hanning Creek near Troy.
The dam stands 22 feet tall and stretches 900 feet across, has a maximum storage capacity of 728 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1972, 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.
