Bureau of Reclamation drilling crews began working on the crest of Blue Mesa Dam, Sept. 12, continuing through about Oct. 2. Workers will drill three sample holes and install equipment in one of the holes to monitor dam activity.
The information gleaned from the core samples and equipment will be used by Reclamation for consideration of short and long-term performance of the dam related to dam safety and security measures.
Blue Mesa Dam is the first of three dams, including Morrow Point and Crystal Dams, which create the Wayne N. Aspinall Unit of the Colorado River Storage Project from which Western markets hydropower. The drilling will not impact hydropower generation.
