Hmmm. Not so sure.

They are pulling water off the top of a very wide river. It is not going to be as turbid.

It is going to be hauling arse through a very wide, very deep area for a very long time. I don't know that a foot or two in the starting height will make any difference at all.

Actually when they did the Bonnet Carrie, they opened just 28 Bays at first, to allow the water to slowly fill in to prevent washout. (there is a surface Road, right in front of the structure).

I think letting the water in too fast, tears the ground up. Plus the way the Spillway is designed, you open one gate at a time. So there will never be a colossal wave of water, all at one time.
