I see they are flooding the Grand Canyon again.

My self and 3 bodies all chipped in and bought a place south of Bythe in 1983. It flooded that summer and we lost it. Old man Gillmore charged us $200 per year space rent for a mobil next to the water. I could not believe it. The hole community of "Gilmore's Camp" just disapeared. There was much damage in Parker etc. Any of you old timers remember?

Oh yeah. Stood on the dam and watched the water go over the spillways for the first time in the history of Lake Mead. Mother nature and the dept of Army Engineers caused your grief

I remember it very well. :) Even have some pictures of Parker flooded somewhere.

There is a show that was on KCET called the Cadillac Desert that showed the water cresting 6 inches above the dam at Lake Powell. The Army Corp of Engineers had mounted ply wood on top of the dam to hold the water back. It was unreal. The water crested onto the ply wood for few hours.

They were letting max water out of Hoover and still a 4 ft wall of water was going over the emergancy spillway for 2 weeks. It has never done that before. I have pics but non are digital. I have another friend who lost his place all the way to Mexico. Never got anything out of it by Insurance money.

Bureau of Reclamation actually, they really dodged a bullet! I’ve got a video showing the event. Water started going over the spillways (one on each side) for the first time. The spillways dumped into bypass tunnels on either side of the dam. These tunnels sloped down steeply through the native sandstone in the canyon walls, and then shot out into the river below the dam. The water was traveling about 120 mph as it hit the bend near the bottom of the tunnel. After awhile, the water started looking reddish, the same color as the native sandstone. The Bureau realized they had a problem, shut off the flow, installed the flashboards and went inside the tubes to take a look.

Cavitation was the culprit, the concrete lining of the tunnels eroded away exposing the native bed rock. Huge holes were found at the bend of the tunnel, big enough to drop a house in.

The Bureau’s lab in Denver went to work on a solution, adding an “air slot” to entrain air bubbles in the water eliminating the problem. Quite a construction project. As a Civil engineer specializing in Water Resources and Flood Control, this is one of the more “interesting” problems I’ve run across.

There's a photo of the damage to one of the diversion tunnels here: http://www.earthscape.org/p2/hp/hp_sum99/hp_sum99a.html

Every time I see a photo of those tunnels I'm amazed at much water must have been running through them to do that much damage.

That's a great program. Years back I got to interview Floyd Dominy in a water-related lawsuit. He was old as the hills, but sharp as a whistle. Lived on a nice piece of Vermont land too.

Post up some pics - I love this kind of stuff
(does anybody else's wife start whispering "nerd alert, nerd alert" when you get excited over dam and water issues?)
