Fish and Aquatic Life
About 34 miles of the Bad River fall within this watershed, almost all of it within the Bad River Indian Reservation. The stream is considered a warm water sport fishery important for spawning walleye and lake sturgeon, as well as supporting migratory runs of trout and salmon species. Other fish found in the lower portion of the river include muskellunge, northern pike, rock bass, pumpkinseeds, bullheads, black crappies, smallmouth bass and yellow perch. This stream's total length is 76 miles from its headwaters in Caroline Lake and has many larger tributaries, among them the White, Potato, Marengo and Tyler Forks rivers. Thus, the lower watershed reflects a river carrying a significant load of sediment and capable of carrying a tremendous amount of water. Due to clay soils that promote rapid runoff, the river is susceptible to rapid flow fluctuations and can move tremendous amounts of sand. Annual mean discharge of suspended sediment was recorded as 618 tons a day, with a high of 8,210 tons/day and a low of 5.7 (STORET). The lower reach tends to be broad and sluggish with a low gradient. Water sampling has shown temperatures that can reach ranges that are close to lethal for trout. Periodically high levels of fecal coliform bacteria have been measured in lower portions of the watershed.
This watershed is largely forested and at risk of experiencing the effects of clearcutting and logging traffic in the highly erodible clay soils. Much of this watershed was at one time covered by boreal forest and mixed conifer, species that protected the easily disturbed soils with their deeper root systems, protective canopies and relationship with soil moisture. Today these forests are dominated by aspen and low-quality second growth hardwoods.
Copper Falls State Park protects the confluence of the Bad and Tyler Forks rivers. The park has three major waterfalls, a deep granite gorge, older growth pine, hemlock and hardwood forest. The park has a WPDES permitted discharge to the Bad River. This discharge appears to occur upstream of the Tyler Forks confluence, placing the discharge in the Upper Bad River.
The Bad River and Bad River Slough are identified in the Lake Superior Coastal Wetland Evaluation (Epstein 1997) as aquatic priority sites. The Bad River originates in the Winegar Moraines subsection, crosses the Gogebic-Penokee Iron Range subsection, and finally flows through Lake Superior Clay Plain subsection, making it one of the most hydrologically diverse streams in the basin. Limited sampling turned up a moderate number of taxa, mostly dragonflies. One rare species was found. This stream also contained taxa not found elsewhere in this study. Management concerns include exotic species, toxic chemicals, bank erosion, silt and impoundment.
The Bad River Slough is a hard water drainage lake adjacent to Lake Superior with a broad outlet channel to the Bad River. Water entering the slough can be from three different sources, depending on conditions. Normally, drainage water from Honest John Slough flows through. Waters from Lake Superior and the Bad River often enter the slough. A regionally significant mussel bed is located in the outlet channel and contains rare species and species not known elsewhere in the Lake Superior Basin. The fishery is reportedly very diverse and includes Lake Sturgeon.
Determination of mussel population dynamics and clarifying taxonomic status of unusual forms is recommended. Threats to the aquatic features are diverse as the site lies at the mouth of the largest stream system in the Wisconsin portion of the basin.

Bad River was assessed during the 2018 listing cycle; new chloride sample data were clearly below the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water was meeting this designated use and was not considered impaired.

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 2016 . See also 'monitoring' and 'projects'.

Water Quality Planning
The work includes monitoring waters for the purposes of updating waterbody assessment status (i.e. future monitoring for 303(d) or ERW/ORW status), for making managment recommendations and updating water body and watershed narratives in WATERS and for use in watershed planning. Collect background water quality information within a watershed and adjacent watershed with a known iron ore deposit. The Monitoring stations to be determined after field recon.
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 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.

Bad River is located in the Upper Bad River watershed which is 134.68 mi². Land use in the watershed is primarily forest (73%), wetland (24%) and a mix of open (1.30%) and other uses (1.70%). This watershed has 213.47 stream miles, 1,110.24 lake acres and 20,385.83 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Not Available for runoff impacts on lakes and Low for runoff impacts on groundwater and therefore has an overall rank of Low. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.However, all waters are affected by diffuse pollutant sources regardless of initial water quality. Applications for specific runoff projects under state or county grant programs may be pursued. For more information, go to surface water program grants.
