Fish and Aquatic Life
Post Lake, Upper, in the Upper Wolf River and Post Lake Watershed, is a 765.17 acre lake that falls in Langlade and Oneida Counties. This lake is an outstanding/exceptional resource water under NR102 under the Fisheries Program. This lake is managed for fishing and swimming and is currently considered impaired.

Surface Acres = 756.7, Maximum Depth = 14 feet, Secchi Disk = 4
A medium hard water drainage lake (impoundment) having
slightly alkaline, light brown water of low transparency. The
immediate shoreline is mostly upland (95%) with the remainder being
wetland. Composition of the littoral materials are sand (80%),
gravel (10%), and muck (10%). Fish species inhabiting this lake
include muskellunge, northern pike, walleye, largemouth and
smallmouth bass, perch, bluegill, black crappie, pumpkinseed, black
and yellow bullhead, white sucker, common shiner and golden
shiner. Aquatic vegetation is sparse. Four inlet streams
contribute water to this lake including the Wolf River,
Pollock Creek, Walczak Creek and Creek 2-14. The upper most
portion of this lake lies in Oneida County. The outlet channel is
navigable and is connected to Lower Post Lake. A public boat
access with parking is located on the west shore and on the south
shore near the outlet channel. Navigable water access ispossible
via the Wolf River, Pollock Creek and the outlet channel. A total
of 0.03 mile of the lake's 7.60 miles of shoreline is public
frontage and controlled by the Town of Elcho. A water control
structure (3 head feet) on lower Post Lake maintains the water
level on this lake.

Upper Post Lake (WBIC 299200) was placed on the impaired waters list for total phosphorus/excess algal growth in 2014. The 2018 assessments showed continued excess algal growth; new chlorophyll-a sample data exceeded the 2018 WisCALM listing thresholds for the Recreation use. Based on the most updated information, no change in the existing impaired waters listing was needed.

Upper Post Lake (299200) was placed on the impaired waters list for total phosphorus/excess algal growth in 2014. The 2016 assessments showed continued excess algal growth; chlorophyll sample data exceed 2016 WisCALM listing thresholds for the Recreation use, however, total phosphorus did not exceed REC thresholds. Total phosphorus and chlorophyll data were clearly below Fish and Aquatic Life listing 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.

Upper Post Lake is located in the Upper Wolf River and Post Lake watershed which is 203.31 mi². Land use in the watershed is primarily forest (52.90%), wetland (35.60%) and a mix of open (6.40%) and other uses (5.20%). This watershed has 202.70 stream miles, 7,524.17 lake acres and 32,034.92 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Not Ranked 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.
