About Upper Big Blue River Structure No. 14
The primary purpose of Upper Big Blue River Structure No. 14 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 Big Blue River Conservancy District (local government). It impounds the Pink Creek near Stone Quarry Mills.
The dam stands 38 feet tall and stretches 812 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 3,200 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1971, 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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 02/21/2018.
