there is a reason they wait and it's not quite so obvious, namely: THEY WANT SO MUCH POWER BEHIND THE RELEASE THAT SAND AND SILT DON'T CLOG THE FIRST FIVE MILES OF THE SPILLWAY. in a slow-mo release, the great muddies' sediment settles out rather quickly, reducing the force of all that comes after it. a niagra style release pushes all that silt for miles and miles before it settles.
