Businesses in downtown Decatur, Arkansas, were flooded early Saturday when an earthen dam broke, causing a sudden flood. Water rushed into the office at an auto-sales shop and swept up a couch, pinning Beverly Harris against a wall. She says, "One minute we had a small amount of water and the next it was between two and three feet high." Four feet of water filled a muffler and auto parts store, carrying tires and equipment up to a half-mile away. It was unclear how the dam broke, or who owned the dam and the pond it held back. Resident say it burst shortly after midnight, after the area had been drenched by five to six inches of rain.
