The National Weather Service says a weak tornado caused minor damage at Lake Cochrane in Deuel County over the weekend.
The Saturday afternoon twister had estimated peak winds of 75 mph and was rated an EF-0, the weakest on the enhanced Fujita scale.
Weather service officials say the tornado touched down on the lake's northern shore and traveled less than a mile before lifting. It caused mainly minor damage to docks, boats, boat lifts, canopies, trees and shrubs, though two houses suffered damage. One lost a portion of its roof.
