And now Fort Peck Dam's safety called into question and reports that Montana will flood again?... Possibility of failure at the Fort Peck Dam could lead to a domino-like collapse of all 5 downstream dams in the Missouri River Mainstem Reservoir System. "It probably would wreck every bridge, highway, pipeline and power line, and split the heartland of the nation, leaving a gap 1,500-miles wide,"... "Countless sewage treatment plants, toxic waste sites and even Superfund sites would be flushed downstream. The death toll and blow to our economy would be ghastly."... Shanks based his doomsday scenario on the fact that Fort Peck Dam is North America's largest hydraulic-fill earthen dam. Such dams are prone to "liquefaction," meaning they can become water-logged and disintegrate if exposed to extreme pressure or seismic activity. For that reason, California replaced most of that state's hydraulic-fill dams. Daggett said such fears are unwarranted at Fort Peck. "I'm amazed that a person who is supposedly an expert on the subject would write such an article," (I AM TOO...HMMMM) Daggett said.(John Daggett, dam operations manager for the Army Corp of Engineers) "We're not in earthquake zones like dams in California." Daggett said the nearest seismically active area is near Yellowstone National Park, about 300 miles away. He added that recent earthquake activity in Yellowstone Park didn't even register at the Fort Peck Dam. http://www.greatfallstribune.com/article/20110613/NEWS01/106130301/Fort-Peck-officials-work-stay-ahead
