I should add that the out-flow is about ten times the normal discharge. It jumped the Osage River below about six feet in an hour or two it took to open them.
In the 51 flooding they kept them closed as long as they could to help the Missouri river downstream of the Osage but when they did open them it was TWICE this flow and stayed open for a week as I remember my Dad’s account.
oh, damn. I just looked at the radar for down there again.
Holy cow!
