Actually, you might not be, as I understand it, they are TRYING to get the construction equipment out of the lagoon by Labor Day, but they might not make it. Then they will slowly refill the lagoon, it will take a few days to get it up to the level of the fountains, when they are supposed to stop filling and check things, before starting filling again.
I have always said sometime in September, and it looks like that around mid-September will be when the lagoon will be back to looking normal... But of course, the amphitheater area will still be behind walls, it looks like mid-December will be the finiosh date for that project.
