This undated photo provided by Grant County (Wash.) public utility, the Wanapum Dam on the Columbia River, Wash., is shown. A crack in a spillway pier at the Wanapum Dam on the Columbia River is a serious situation, but not a threat of downstream flooding even in a worst-case scenario, a spokesman for the Grant County Public Utility District said. The 2-inch wide underwater crack extends horizontally across the upstream side of the 65-foot wide pier called a monolith. It's one of 12 monoliths on the spillway.
