The dam operators backed off from 2400 CFS to 2000 CFS, just as last weekend's storms came through. That bumped the lake back up a few inches to 504.9. It seems to have peaked and should be headed down again.
I'm guessing somewhere around 504.6. That's about four inches lower, I don't think we'll make it by Friday. Monday might be a good day, after the bikers leave.
The blue section on this chart is the target:
