CROSS CHANNEL HOLE AND BUNGE SLIP FISH ASSESSMENT

Abstract

The Northwest Regional Planning Commission, the City of Superior and the Wisconsin Department of Natural Resources are with financial assistance from the Wisconsin Coastal Management Program, preparing a plan for long term disposal of materials dredged from the Superior harbor. Two of the potential disposal sites, Interstate hole and Bunge slip, are located within the Duluth-Superior harbor. An environmental assessment of the effects of dredge spoil deposition must be completed before these sites can be utilized as disposal areas. The University of Wisconsin - Superior's Center for Lake Superior Environmental studies was contracted to perform an assessment of the fish populations at the two proposed disposal sites. This assessment included an examina­tion of the utilization of the sites by both resident and transient fish populations in the harbor system.
