Fish and Aquatic Life
West Petenwell Ditch is classified as a Class II trout stream. In response to an increase in agricultural irrigation, a water quality study was conducted by the DNR in 1981 and 1982. Water chemistry results indicated substantial increases in nitrite+nitrate nitrogen between the control and impact stations, suggesting nitrogen compounds associated with agricultural fertilizers are lost to groundwater. Low dissolved oxygen levels in lower portions of the ditch may be due to heavy aquatic plant growth and the low dissolved oxygen associated with incoming groundwater. Also, biotic index samples from this same location indicated "very poor" water quality, which correlates with low dissolved oxygen. Pesticides may also be a problem.
Fisheries Management installed halved logs in the ditch to improve in-stream cover for trout. This ditch is subjected to heavy fishing pressure.

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 and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.
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.

West Petenwell Ditch is located in the Lower Yellow (Juneau Co.) River watershed which is 261.05 mi². Land use in the watershed is primarily wetland (37%), forest (29%) and a mix of grassland (15%) and other uses (18%). This watershed has stream miles, lake acres and 65,343.09 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, Low 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.
