About Stonebridge Lake 12 Dam
The primary purpose of Stonebridge Lake 12 Dam is flood risk reduction.

It impounds the Tr-wilson Creek near Mckinney.
The dam stands 38 feet tall and stretches 800 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 192 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1988, the structure is 38 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 11/29/2016. That was 9 years ago, which is on the longer end for a high-hazard structure.
