At least two dozen people who were trapped by a wall of fire in Butte County survived by plunging into a cold lake. The San Francisco Chronicle reports Tuesday that the people plunged into the Concow Reservoir after flames surrounded their homes in a community outside the decimated town of Paradise. At least a dozen were in a caravan of vehicles that got cut off by the fire last Thursday. California Department of Forestry and Fire Protection Division Chief Garrett Sjolund says firefighters helped fleeing residents, distributing fire shelters to those who couldn’t stand the water. The shelters are a last resort for protection against flames. Concow resident Peggy Moak says she and others pulled people out of the lake with a canoe. Authorities say several of those in the reservoir were hospitalized, some with serious burns.
