About Lake Vann Dam
The primary purpose of Lake Vann 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 Al Vann (private). It impounds the Tr-bowlin Creek near Thompson.
The dam stands 27 feet tall and stretches 2,100 feet across, and has a maximum storage capacity of 1,500 acre-feet. Completed in 1975, 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.
