About Shell Lake

The primary purpose of Shell Lake 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 George H Giger & Judy Duncan (private). It impounds the 4-d Cr near Crescent.

The dam stands 30 feet tall and stretches 1,000 feet across, creates a reservoir covering 20 acres, and has a maximum storage capacity of 1,080 acre-feet. Completed in 1915, the structure is over a century 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 12/14/2010. That was over 15 years ago.
