About Ahlswel Dam
The primary purpose of Ahlswel 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 Gary & Debra Rae Ahl Trustees (private). It impounds the Tr-deer Creek.
The dam stands 18 feet tall and stretches 310 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 90 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1960, 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 11/25/2014. That was over 11 years ago.
