Fish and Aquatic Life
This is a hard water seepage lake. The water is clear, alkaline and has a moderate transparency. Bluegills, yellow perch, bullheads, and white suckers comprise the bulk of the fishery. Northern pike, while present, are scarce. There is public access, at the east end of the lake. Periodic winterkill conditions occur. There are no commercial facilities and thereis one dwelling. Migrating waterfowl likely use the lake and mallard nesting has been reported.

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.
Adams County proposes to wrap up its county-wide lake classification effort. Major project elements to include: 1) completion of water sampling, 2) development of lakes classification report and individual lake summaries, 3) development of a powerpoint presentation, 4) four public meetings, 5) expansion of shoreline restoration packet.
Adams County continue its lake classification efforts through collecting and assessing chemical and biological data on all lakes within the county that afford public access. Major project componants to include: 1) collection and assessment of chemical and biological data, 2) development of a "library" of information for public use, 3) development of management recommendations, 4) I&E for riparians and lake users.
Adams County proposes to initiate a Lakes Classification effort to assist in comprehensive plan development for communities surrounding its lakes with public access. Phase 1 elements, to be funded with this grant, include: 1) delination of surface watersheds and flow patterns, 2) delineation of ground watersheds, 3) identification and mapping of land uses, 4) inventory and mapping of shoreline erosion and development problems, 5) identification and mapping of sensitive/critical areas and natural heritage habitats, 6) verification of wetland delineations, 7) delineations of lake watersheds, 8) development of lake maps
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.

Fenner Lake is located in the Montello River watershed which is 134.50 mi². Land use in the watershed is primarily forest (46.40%), agricultural (27.10%) and a mix of wetland (15.30%) and other uses (11.00%). This watershed has 156.65 stream miles, 768.66 lake acres and 11,663.70 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium 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.
