Fort Peck Dam [SEP] Dam failure during construction
The west end of the slide mass broke away from the dam near station 27+00 and the core pool water rapidly poured out of the breach that was created in the shell. Portions of the core in the still-stable portion of the dam continued to slump into the hole created by the loss of the slide mass. One construction supervisor was backing his car away from the advancing scarp to the west along the beach to avoid the slumping and noted that the small scarp in the core was advancing to the west at a speed equal to his own (approximately 10 mph (16 km/h)).
