If they were to remove the North side of the water park refilling the lake might be a decent financial choice as they could probably simply submerge much of the existing cement without having to pay the expense of removing it. That protecting racer during the work and preventing flooding under racer and into the existing South side water park during significant storms might be a challenge. I would love to see the lake return but I don't know that it's a likely situation at the moment or even a financially viable one.
