Five unnamed tributaries to the Marengo River are Class I trout streams and are classified as exceptional resource waters. These streams are all incorrectly located in Wisconsin Trout Streams based on their headwaters, not their outlets. The tributary listed as T44N R5W S17 is in Section 16 NWNE. This stream is a small spring stream populated by brook and brown trout. There may be inadequate in-stream food sources. The stream has a stable bottom of rubble, gravel, boulders and sand. Bank vegetation is upland hardwood.
The stream listed as T44N R5W S20 is in Section 16 NESE. This stream is a small spring-fed stream with brook and brown trout. Sculpins are abundant. The trout are stunted, which may indicate a lack of in-stream food sources. Cover is good and stable rubble, boulder, gravel and sand make up its bottom. The bank is vegetated by upland hardwoods. Both of the preceding streams flow mostly within Chequamegon National Forest lands.
The stream listed as T44N R5W S21 is in Section 15 according to 1984 1:24,000 scale topographic maps, though Surface Waters of Bayfield County identifies the stream as entering in Section 16. This stream is a small brook trout stream flowing north along the west side of the old Grandview Quarry. The trout are small, indicating an inadequate supply of food. Adjacent to the quarry, stream bottom types are mainly sand, gravel and crushed granite. Above the quarry, little granite is present. Most of the streambanks are in private ownership.
The stream listed as T44N R5W S3 is located in Section 9. This is an excellent spring-fed feeder for spawning brook and brown trout. Resident trout are small, indicating an inadequate food supply. The entire stream is bordered by upland hardwoods of the Chequamegon National Forest and bottom conditions are stable gravel, rubble and boulders.
The stream listed as T45N R5W S9 is in Section 1 NWNW. This stream supports a population of small brook trout. It has an unstable silt and clay bottom. The entire stream is bordered by upland hardwoods. Trout habitat appears to be good, but there is inadequate food supply. The stream flows through privately held lands.

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'.
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.

Unnamed is located in the Marengo River watershed which is 217.53 mi². Land use in the watershed is primarily forest (67.40%), wetland (15.30%) and a mix of grassland (11.60%) and other uses (5.70%). This watershed has 450.89 stream miles, 1,497.18 lake acres and 18,112.32 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium 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.
