Things have to get taken down at times to get fixed or replaced- fact of life. I've stayed there before when the spring was down and we still, somehow, managed to have a great vacation. Everyone just calm down. We are there from July 10-15 for an on-site wedding and while I hope it's running by then, if it's not we'll probably say "Too bad" and move on. It's not going away as it is integral to the story of the resort. It's at the heart of the reason/back story for the WL as it "creates" the pool and stream (not really, but it's a well hidden trick). Any water feature adds a bunch of maintenance to any attraction or display as water by it's nature corrodes most materials. Unavoidable.
I do think that the ring of foliage is pretty tacky looking, but it's either that or it just sits there dry and all ugly looking.
