Fish and Aquatic Life
Overview
Lake Superior is the largest freshwater body in the world (third by volume). The St. Louis River, draining approximately 3,634 square miles of northeastern Minnesota and northwestern Wisconsin, is the major U.S. tributary to Lake Superior. Beaches along Lake Superior are under recreational restrictions due to high counts of E. coli.

Condition
Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water monitoring program uses a media-based, cross-program approach to analyze water condition. An updated monitoring strategy (2015-2020) is now available. Compliance with Clean Water Act fishable, swimmable standards are located in the Executive Summary of Water Condition in 2018. See also the 'monitoring and projects' tab.
Reports
Recommendations
Aquatic Plant Monitoring or Survey
Miller Dam Lake (Chequamegon Waters Flowage) Association will conduct an Aquatic Plant Survey
Aquatic Invasives Research
This project will prioritize management actions based on threats posed to culturally significant resources by invasive plants. GLIFWC has documented over 8,000 non-native invasive plant sites in the Lake Superior counties of Wisconsin and Michigan. This data is being used to develop species distribution models for invasive plants. GLIFWC will develop similar models for culturally significant native species. Comparing these models will identify which invasives pose the greatest risk, and help prioritize areas for early detection/rapid response efforts.
Project Deliverable
This project will provide the following deliverables for the entire south shore of Lake Superior in Wisconsin and the Upper Peninsula of Michigan: 1) electronic device, toxic waste material, and petroleum based oil collection; 2) creation of a GIS data layer that identifies the locations of business and industry that contain hazardous materials in their MSDS and/or waste stream; and, 3) create/disseminate information to the public regarding the effect toxins have on the Lake Superior watershed - particularly the toxins contained in electronic devices.
Aquatic Plant Monitoring or Survey
Area infested by invasive species
Baseline: 4100 feet
Value at Grant Completion: 0 feet
Long-term Value: enhances recovery of native plant community
Year Long-term Value will be Achieved: 2011
Monitor Fish Tissue
GLIFWC will determine mercury levels in walleye, lake trout, whitefish, cisco, and siscowet from Lake Superior and walleye from inland lakes. Test results for selected fish species and areas in Lake Superior will be compared with data from previous testing. Results from inland waters will be used to update tribal and lake specific GIS maps and consumption advice aimed at reducing health risks associated with consuming mercury contaminated walleye.
Habitat Restoration - Upland
Native vegetation cover
Baseline: <50%
Value at Grant Completion: >90%
Long-term Value: restores native plant communty
Year Long-term Value will be Achieved: 2011
Monitor Targeted Area
The Chequamegon Bay Area Partnership requests funding to provide beach sanitary surveys on eight previously un-surveyed beaches on tribal lands and implement actions to target, reduce, and remove the contamination identified in the watershed.
Restore Riparian Habitat
The Chequamegon Bay Area Partnership (CBAP), a collaboration of educational staff, tribal agencies, local citizens, natural resource agencies, and local governments, through lead applicant, Northland College, will restore and protect fish and other aquatic organism habitat in tributaries of the Chequamegon Bay watershed of Lake Superior. Projects reduce erosion and sedimentation through proper design and replacement of degraded culverts and will restore connectivity of tributaries to the lake by removing structural impediments to fish and other aquatic organisms. This proposal incorporates planning, design, implementation, and monitoring of fish and aquatic organism passage.
Monitoring Ecosystem
Under this project and with assistance from WDNR, Lake Superior Research Institute (LSRI) will conduct a comprehensive ecological assessment of Wisconsins Lake Superior basin communities identified as priority areas by the WDNR Plan. Sites and parameters proposed in this project were selected using guidance from the Wisconsin Great Lakes Strategy, the Lake Superior Binational Work Group 2011 Monitoring Priorities, and discussions with WDNR Lake Superior fisheries biologists and resource managers and are identified in the WDNR Plan. Sites included in the project are not part of the National Coastal Condition Assessment.
Recreational Use Survey
The Great Lakes are the recreational outlet for millions of individuals and the need to close beaches should be kept to a minimum. The Great Lakes Regional Collaboration has as a goal the 90 95% reduction in chemical, algal, and bacterial contamination through the identification of nonpoint source pollution, implicated as a major source of contamination to the recreational waters of WI. Pollution of the nearshore waters of Lake Michigan and Lake Superior not only poses a threat to public health, but also to the economic wellbeing and quality of life for WI residents. Pollution of nearshore water quality also has ramifications for ecosystem health.
Restore Riparian Habitat
Shoreline feet restored/enhanced
Baseline: 0 feet
Value at Grant Completion: 4100 feet
Long-term Value: restores natural plant and wildlife community
Year Long-term Value will be Achieved: 2011
Information and Education
The Forum proposes to complete five outreach activities that promote the goals of the Lakewide Management Plan (LaMP) and the Great Lakes Regional Collaboration (GLRC). These activities target multiple primary audiences: public stakeholders; local elected officials; the faith community; recreational kayakers/canoeists; marina owners and users; and several secondary audiences. All audiences are positively affected by these outreach activities as we inform lake stakeholders how to reduce negative impacts on their communities and promote sustainable lifestyle choices, thus improving the overall quality of life in the basin. These projects include the following: 1. Launch a Lake Superior Stewards Project to Build Watershed Capacity 2. Develop a Bernie the Burn Barrel Display 3. Promote Climate Change Outreach to Watersheds through Webinars and Collaborations 4. Expand Education/Outreach about LaMP Priorities: Outreach at Special Events 5. Hold Special Meetings with Local Elected Officials to Build Watershed Capacity
TMDL Implementation
St. Louis River system exceeds water quality criteria, including wildlife and human threshold and human cancer. Fish tissue confirms fish consumption advisories for the river.

Monitor AOC Beneficial Use Impairments
Hog Island. This project involves evaluating 303d waters including Newton Creek and Hog Island Inlet which is required for proposing removal of waters from the state's impaired waters list. To complete necessary monitoring as required by EPA.
Sediment Remediation
Conduct sediment sampling to determine the extent of contamination in Howards Bay and continue actions to advance remediation of contaminated sediment in the Bay.
Restore Riparian Habitat
Habitat Restoration - Instream
Conduct mulitple restorations in Wisconsin's Lake Superior Basin annually. Up to 100% funding of restoration costs. A 10 year voluntary agreement is required.
Management Goals
Wisconsin's Water Quality Standards provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable
Management goals can include creation or implementation of a Total Maximum Daily Load analysis, a Nine Key Element Plan, or other restoration work, education and outreach and more. If specific recommendations exist for this water, they will be displayed below online.
Monitoring
Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy was recenty updated.
