Fish and Aquatic Life
Overview
North Twin Lake, in the East Fork Chippewa River Watershed, is a 30.18 acre lake that falls in Iron County. This lake is managed for fishing and swimming and is currently not considered impaired.

North Twin Lake, T44N, R1E, Section 29
Surface Acres = 35.7, S.D.F. = 1.19, Maximum Depth = 7 feet
A very soft water seepage lake having acid, light brown
water of low transparency. The outlet stream, which does not
afford any boating use, is tributary to Shine Creek and part of
the Tyler Forks River drainage. It is possible that the outlet
may be intermittent. The entire littoral zone is composed of
muck. About half of the shoreline is upland with the balance
being wetland of the bog-coniferous type. Largemouth bass, perch
and bluegill inhabit this lake. Waterfowl may use this area.
Floating vegetation is moderate in density throughout half of the
lake basin while submergent vegetation is dense. There are no
developments located on the shoreline. There is no public
access. Private forest crop land abutting on this lake does
afford an opportunity for conditional access of the wilderness
type at the present time. The lake's shallow depth suggests that
winterkill may be a problem.

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
Twin Lakes is located in the East Fork Chippewa River watershed which is 305.16 mi². Land use in the watershed is primarily forest (63.90%), wetland (32.70%) and a mix of grassland (1.60%) and other uses (1.70%). This watershed has 310.53 stream miles, 2,431.41 lake acres and 65,073.81 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Low 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.
