After 60 years, the design flood for the Bluestone dam changed requiring a modest raise and a number of other improvements totaling some $130 million thus far and another estimated $200 million in improvements still to go. Check out the size of these anchors being use to anchor the dam foundation into bedrock. This is just one of 150 anchors. The article also discussed how the rock strength parameters used to design the dam 60 years ago were developed using the state of the practice at the time, new rock strength parameters are lower using current design standards.

So for these reasons, for safety, quality, the accuracy and the consistency of the drill holes are much better done from a platform, they proposed this road cut type of a platform."

The drilling is for grouting remediation of the dam foundation. Story from Herald-Citizen, Cookeville, Tennessee.
