Right now, if I am reading the charts correctly, they are running 14K CFS over the dam. The Kings has crested and is dropping fast, but it is still running 20KCFS into the lake. The James is still coming up a bit and is running at 14K CFS. Lake is up 4 feet and is still rising.
I can't find anything that states how long they'll leave the flood gates open. Probably depends on how high they'll let Bull get and how much water they can run out of Bull.
However, I think you'll be fine next week, I'm assuming you can dock your boat at the resort so you won't have to deal with flooded ramps. Weather looks to be nice all week, sunny and warm, would not surprise me if a lot of fish are up on the bank, fishing could be really good. You will have to look out for floating wood out on the lake, but other than that, things may work out well for your trip.
