Fish and Aquatic Life
Overview
North Turtle Lake is a drainage lake of moderate fertility, having light brown, slightly alkaline water of moderate transparency. The bottom materials consist mostly of sand with rock and gravel. Both the inlet and the outlet streams are considered navigable. The muskellunge, northern pike, walleye, largemouth bass, smallmouth bass and pan fish compose the principal fish species present. Public access is possible either by navigating the inlet or outlet streams, or by the use of a county road without nearby parking facilities. Public use facilities consist of three resorts and one boat rental establishment. There are 42 cottages located on the shore line.

Impaired Waters
North Turtle Lake was listed in 1998 for Mercury from atmospheric deposition and is proposed for removal based on 2001 updated Fish Consumption advisories.
This lake was assessed for phosphorus and algae in 2012, 2014 and 2020; phosphorus levels in 2020 were too high for healthy plant, bug, and fish communities.

Condition
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.

Management Goals
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
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.

Watershed Characteristics
North Turtle Lake is located in the Flambeau Flowage watershed which is 247.18 mi². Land use in the watershed is primarily forest (56.80%), wetland (28.20%) and a mix of open (14.10%) and other uses (0.90%). This watershed has 190.98 stream miles, 10,199.06 lake acres and 43,978.35 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.
