Fish and Aquatic Life
Big Trade Lake, in the Trade River Watershed, is a 327.30 acre lake that falls in Burnett County. This lake is managed for fishing and swimming and is currently not considered impaired.

These four lakes are situated on the Trade River. They have been united under a common
lake association for many years. The Round - Trade Lake Improvement Association (including
Spirit & Long Trade Lakes) has been an active and enthusiastic leader in the pioneering efforts
at lake management in Wisconsin. The four lakes along the Trade River have exhibited signs of
excess fertility for decades. A history of chemical treatment efforts is noted in the files for
Long Trade (Atlas), Round and the Trade Lakes (Big & Little).
The signs of eutrophication are evident on these waters but a definitive nutrient and hydraulic
budget has not been documented. A feasibility study to evaluate the hydraulic and nutrient
loading to the lakes as well as in-lake monitoring to determine recycling and profile
characteristics is a high priority for these lakes. A lakes planning grant or possibly a Clean
Lakes grant study is a possibility.
WRM district staff have been working with this lake group to start the process towards a long
range lake management plan. Self-help volunteers are in place on all four lakes and Round
Lake was one of the original "expanded" monitoring group.

Source: 1966, Surface Water Resources of Burnett County Trade Lake, T37N, R18W, Sections 20, 21, 28, 29 Surface Acres = 432.1, Maximum Depth = 34 feet, M.P.A. = 91 ppm, Secchi Disk = 3 feet A hard water, drainage lake on the Trade River. Estimated outlet flow is approximately 23.7 cubic feet per second. Fish species present include northern pike, walleye, largemouth bass, bluegill, black crappie, perch, rock bass, pumpkinseed, bullhead, carp, white sucker and bowfin. Carp are a problem. Lakeshore vegetation is upland except for 32 acres of wetlands which provide habitat for muskrats, nesting mallards, blue-winged teal and wood ducks. Migratory diving ducks also use the lake. A town road access with parking is provided on the southern most part of the lake. There is 0.49 miles of public frontage which includes the access, an undeveloped platted access, state-owned island frontage and other state land. Private development consists of one resort, two boat rentals and 87 cottages.

The 2018 assessments of Big Trade Lake (WBIC 2638700) showed impairment by phosphorus; new total phosphorus and chlorophyll-a sample data was insufficient for assessment. This water was meeting its designated uses and not considered impaired; however, further monitoring was recommended.

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.

Big Trade Lake is located in the Trade River watershed which is 194.93 mi². Land use in the watershed is primarily forest (56.40%), wetland (18.80%) and a mix of grassland (11.70%) and other uses (13.10%). This watershed has 166.68 stream miles, 2,902.48 lake acres and 21,757.05 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium 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.This water is ranked High Lake for individual Lakes based on runoff problems and the likelihood of success from project implementation.
