Residents in the island town of Sabula are watching the dike that’s keeping the flooding Mississippi at bay. Rick Dickinson, one of the town’s 770 residents, says sump pumps are working overtime. He says after a while you hear the pumps only when they stop.Dickinson says city workers are monitoring the seepage along the earthen dike. He says the river was raging Monday due to high winds.Dickinson says everybody’s pitching in and helping in the flood fight, which he says is the beauty of a small town. The river crested at 21-feet-one-inch on Sunday night in Sabula, which is seven or eight inches below the record 1965 flood.There’s only one way into Sabula today, and only residents and emergency crews are being allowed in.
