Fish and Aquatic Life
Hills Lake, in the Pine and Willow Rivers Watershed, is a 124.68 acre lake that falls in Waushara County. This lake is managed for fishing and swimming and is currently considered impaired.

A medium-sized lake located in the northeast quarter of the Township of Mount Morris. The lake is landlocked with seepage as the primary water source. The lake appears to be a two basin lake; however, the physiography of the bottom shows characteristics of a single basin with contours culminating to the maximum depth in the eastern half of the lake. The littoral zone is not extensive along the lake as there are marked drop- offs along the northeast shore, and along sections of the eastern shore. The littoral bottom materials consist almost entirely of sand mixed with some gravel and rubble. The nearly one square mile watershed area of this basin is entirely wooded. The fishery consists of largemouth bass, perch, crappie, bluegills and common sunfish. A few large northern pike are also present. Shoreline development is gradually increasing with the presence of 82 cottages and dwellings present. One private campground, picnic area, and a beach are also present. No waterfowl or other wildlife were observed during the investigation.

Hill Lake (182100) was placed on the impaired waters list for Mercury in fish tissue in 1998. This water was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data were clearly below 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. This water was also assessed for chlorides and sample data were clearly below 2016 WisCALM chronic and acute listing criteria for the Fish and Aquatic Life use. This lake is considered impaired for Fish Consumption use and meeting REC and FAL uses.

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.

Hills Lake is located in the Pine and Willow Rivers watershed which is 302.08 mi². Land use in the watershed is primarily forest (34.40%), agricultural (27.80%) and a mix of wetland (19.20%) and other uses (18.70%). This watershed has 377.48 stream miles, 11,273.01 lake acres and 33,136.61 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.
