About Wilsonville Dam
The primary purpose of Wilsonville Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by David L & Margaret E Ruf (private). It impounds the Tr-beaver Creek near Wilsonville.
The dam stands 17 feet tall and stretches 435 feet across, creates a reservoir covering 24 acres, has a maximum storage capacity of 246 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1961, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life.
