cumberland river levels

I was wondering with the work that is going on at the dam at wolf creek, how high are the water levels and are they stable. I have a pontoon boat and was wondering about the depth of the water and the rise and fall. I sure do not want to get out there and end up dry beached waiting for them to release more water.I have launched my old john boat at Burksville and had no problem but it did get a little dicey after a few miles upstream and we had a sand bar. Some one liberated my 10hp for jon boat back three years ago on Barren River Lake so it will not cut it like it used to. Thanks for any info
