The South Branch of Ten-mile Creek/Ditch No. 6, 11 miles long is classified as Class I (mile 4.4 - 11.2) and II (mile 0 - 4.4) trout water. Mile 6.9 - 11.2 is condsidered an Exceptional Resource Water. The lower eight miles was ditched in the early 1900’s to drain the land for agricultural use. This portion of the stream is dredged periodically to remove sediment and vegetation from the channel. Other impacts to the stream include heavy irrigation, which reduces base-flow, pesticide use, streambank pasturing and sedimentation from wind erosion.
In-stream cover is poor on 60 percent of the creek. Stream habitat work would benefit the stream but cost is prohibitive. Old "V-type" deflectors are still in place but are causing more harms than good by acting as dams.

The South Branch of Tenmile Creek (also know as Ditch No. 6) was assessed during the 2018 listing cycle; new temperature 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.

The 2018 assessments of the South Branch Tenmile Creek (Tower Rd to the headwaters) showed impairment by temperature; new temperature sample data exceeded the 2018 WisCALM listing criteria for the Fish and Aquatic Life use. Based on the most updated information, this water was proposed for the impaired waters list.

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'.
Monitor Targeted Area
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.

South Branch Tenmile Creek is located in the Sevenmile and Tenmile Creeks watershed which is 112.24 mi². Land use in the watershed is primarily agricultural (48%), forest (31%) and a mix of grassland (9%) and other uses (11%). This watershed has stream miles, lake acres and 10,480.58 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Low 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.
