Fish and Aquatic Life
Poskin Lake, in the Yellow River Watershed, is a 153.51 acre lake that falls in Barron County. This lake is managed for fishing and swimming and is currently not considered impaired.

A hard water drainage lake on the Vermillion River. It has a one-foot water control structure on its outlet owned by Stanley Kris. The fish population consists of northern pike, largemouth bass, bluegills, black crappies, perch, pumpkinseeds, bullheadsand white suckers. The slow growth of the panfish is a management problem. Most of the lakeshore is open farmland with the exception of a six-acre marshy wetland area near the inlet which provides habitat for muskrats, nesting puddle ducks and mergansers. The town road access is located on the west side of the lake. Private development consists of one resort, a boat rental, and 36 cottages and homes. There is no other public frontage other than the access points.

Poskin Lake (WBIC 2098000) was placed on the impaired waters list in 2012 for total phosphorus and in 2014 for eutrophication caused by an unknown pollutant. The 2018 assessments showed continued impairment by phosphorus; new total phosphorus and chlorophyll-a sample data clearly exceeded the 2018 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. The Unknown Pollutant listing is proposed for removal in 2018 because the impairment Eutrophication was linked to the pollutant Total Phosphorus.

Poskin Lake (2098000) was placed on the impaired waters list in 2012 for total phosphorus and in 2014 for eutrophication caused by an unknown pollutant. The 2016 assessments showed continued impairment by phosphorus and eutrophication caused by an unknown pollutant; total phosphorus sample data overwhelmingly exceeded 2016 WisCALM listing thresholds for the Recreation use, but not Fish and Aquatic Life use, and chlorophyll data exceeded both REC and FAL thresholds. Based on the most updated information, no change in existing impaired waters listing is needed.

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.

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.

Poskin Lake is located in the Yellow River watershed which is 239.35 mi². Land use in the watershed is primarily agricultural (38%), forest (28.40%) and a mix of grassland (20.50%) and other uses (13.00%). This watershed has 415.31 stream miles, 2,929.80 lake acres and 11,565.29 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Available 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.
