About Conrad Jim
The primary purpose of Conrad Jim 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 Craig A & Alfreda A Moore (private). It impounds the Little Hauani Cr near Lebanon.
The dam stands 20 feet tall and stretches 300 feet across, creates a reservoir covering 3 acres, and has a maximum storage capacity of 80 acre-feet. Completed in 1974, 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. The most recent inspection on record was 05/04/2010. That was over 15 years ago.
