Cranberry Lake, Bayfield County - Critical Habitat Designation

Critical Habitat Designation occurred on Cranberry Lake in Bayfield County during 2007 and 2008. Cranberry Lake, which is a 131 acre lake with a max depth of 12 feet, is part of the Eau Claire Chain of Lakes and is connected to Lower Eau Claire Lake. Access to Cranberry Lake is through navigable water from Lower Eau Claire Lake.

Designations were conducted by a team consisting of the county fisheries biologist, water resources specialist, wildlife biologist, and critical habitat coordinator. Initially, DNR staff compile and review existing natural resource data that help identify areas of focus related to fish, wildlife, endangered resources, and their habitats before going into the field. In the field, staff used existing natural resource data, delineation guidance, and professional judgment to establish the boundaries of the sites containing critical habitat. Critical Habitat Designation boundaries were recorded in the field using map grade Trimble Geo XM GPS Units. For each site, staff inventoried current shoreline management practices occurring along littoral, bank, riparian, and setback zones following standardized methods. Depending on the features of each area being delineated, standardized sampling of emergent and submergent aquatic vegetation, substrate, and woody habitat was also conducted.

Just a few minutes of preventative action can protect our hunting tradition for generations to come. Before launching into and leaving a waterbody, hunters must:

  • Inspect waders, boats, trailers, motors and hunting equipment, including boots, blinds and dogs.
  • Remove all plants, animals and mud.
  • Drain all water from decoys, boats, motors, livewells and other hunting equipment.
  • Never move plants or live fish away from a water body.

A special consideration for waterfowl hunters is to remove all seed heads and roots when using vegetation for your duck blinds. It is important to note that it is illegal to use phragmites in counties where the plant is listed as prohibited by NR40, in general these counties include the western half of Wisconsin.
