The Domino effect

In 1983, the Colorado River experienced record flooding. The dams on the Colorado River held, barely. WI they didn't? The PoD is that the Flaming Gorge Dam in Utah fails for some reason (more water), sending water down the Green River to the Colorado River. This in turn would cause the other dams to fail.

Death toll and damage, anyone?

Long term effects on the US?
