Oil workers try to lift a storage tank for condensate that was knocked over by floodwaters from the Platte River at an oil well site near LaSalle, Colo., on Friday. Condensate is the mix of oil and water that is pumped out of the ground. The tank was intact and had not leaked. Hit hard by the floods was the oil-rich Denver-Julesberg Basin, which hosts about 20,000 active oil and gas wells. About 1,900 wells have been shut down in the aftermath of the disaster.
