About Mcmordie Lake Dam
The primary purpose of Mcmordie 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 John Mcmordie (private). It impounds the Tr-horse Creek.
The dam stands 18 feet tall and stretches 400 feet across, creates a reservoir covering 5 acres, and has a maximum storage capacity of 72 acre-feet. Completed in 1965, 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.
