When we went by in April '13 it looked worse by the Treehouse... but just a few months before, Sept '12, we spent 9 nights at the Treehouse - and there was beach, not water surrounding the bar. Change can happen rapidly, that sand was deposited elsewhere, and I suspect that eventually it will come back... if it doesn't, Treehouse is going to be rebuilding that bar...
This is from Sept. 14, 2012.
