My understanding is that they have finished the first "phase" of the project, grouting the embankment on the left of the dam (looking downstream), and they are getting ready to start grouting the middle section in front of the dam. They are far from done - I think there are a few more years to go.
The repairs at Wolf Creek are a couple years ahead of Center Hill and they haven't authorized Lake Cumberland to go back to normal summer pool yet, so I think we've still got a long time before we see Center Hill filled up again.
