BOX: Goal: Better fishing

To improve the fish habitat provided by Mississippi River wingdams, the Corps of Engineers, which is in charge of maintaining the main channel, is cutting notches in the dams so the river will scour holes below them.

Eric Nelson of the U.S. Fish &; Wildlife Service, which is in charge of maintaining fish and waterfowl habitat on the river below Wabasha, said sand has filled in below some wingdams, leaving no place for fish to feed or rest. But notches will let river water scour out holes below them and provide the habitat, he said.
