My best is it is still there.. a bit hard to see from the top of the rapid if you are running from the highway put in. Best bet is to take out in the big eddy on the right where the white cottage is and talk a quick scout from the cliff... If you feel confident, You can always run the river right line close to the wall and catch the eddy there and see... If youre putting in from Rock Aquaventure and walking back up, it will be easy to see if the tree is still there.
Water should be low... if you have a saw that fits in your kayak and a few ropes, shouldnt be a problem removing it.
Good luck!
