UNNAMED TRIBUTARY TO MULLET RIVER, RM 8.6
T15N R22E Sec. 31 NW NE
Stream Length = 6.0 miles
WBIC = 53600
This stream originates in the Town of Plymouth and flows to the southeast before its confluence with the Mullet River. Land use for the watershed is primarily agriculture, however the stream cooridor does contain numerous wooded and wetland areas. WDNR personnel surveyed the site upsteam of County Highway “PP” in August 1999. The fish community rated poor with fish species listed in Table 56.
Stream habitat rated good with excellent habitat types of riffles, pools, and runs; excellent buffer areas; bottom substrates primarily comprised of rock, gravel, and sand; and minimal streambank erosion. Fish cover in the habitat analysis rated poor due to relatively shallow water depths and lack of physical cover. The benthic macroinvertebrate community rated fair. Water quality may be limited due to low dissolved oxygen levels and nonpoint source pollution from agricultural runoff.

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.
Monitor or Propose 303(d) Listing
Increase monitoring and assessment of Plymouth east tributary (WBIC 53600) relative to impaired water status.
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 Mullet River watershed which is 88.19 mi². Land use in the watershed is primarily agricultural (38.90%), forest (21.40%) and a mix of grassland (17.90%) and other uses (21.80%). This watershed has 97.54 stream miles, 789.87 lake acres and 6,609.38 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Ranked for runoff impacts on lakes and High for runoff impacts on groundwater and therefore has an overall rank of High. 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.
Unnamed Creek is considered a Cool-Cold Headwater, Macroinvertebrate, Cool-Warm Headwater under the state's Natural Community Determinations.
Natural communities (stream and lake natural communities) represent model resultsand DNR staff valiation processes that confirm or update predicted conditions based on flow and temperature modeling from historic and current landscape features and related variables. Predicated flow and temperatures for waters are associated predicated fish assemblages (communities). Biologists evaluate the model results against current survey data to determine if the modeled results are corect and whether biological indicators show water quaity degradation. This analysis is a core component of the state's resource management framework. Wisconsin's Riverine Natural Communities.
Cool (Warm-Transition) Headwaters are small, sometimes intermittent streams with cool to warm summer temperatures. Coldwater fishes are uncommon to absent, transitional fishes are abundant to common, and warm water fishes are common to uncommon. Headwater species are abundant to common, mainstem species are common to absent, and river species are absent.
Cool (Cold-Transition) Headwaters are small, usually perennial streams with cold to cool summer temperatures. Coldwater fishes are common to uncommon (<10 per 100 m), transitional fishes are abundant to common, and warm water fishes are uncommon to absent.
