Long Trade Lake T36N, R18W, Sec. 4, 9 Surface Acres = 151.2, S.D.F.=2.44, Maximum Depth = 11 ft., M.P.A. = 67 A flowage with a navigable inlet and a navigable outlet (22.5 cfs), the Trade River. Fish species present include northern pike, walleyes, largemouth bass and pan fish. Carp are also present but not in problem numbers. It has a .1-acre town park, and a 60 -foot town access road, but is without a parking area. There is one improved private access located at the north end of the flowage. A fee is charged for its use. This flowage has one resort and six cottages on it at present. Muskrats are present. Mallards and bluewing teal nest in its predominantly marsh wetlands. The flowage is maintained by an eleven-foot dam. Apotential pollution problem exists here in that the Atlas Cooperative Creamery has a septic tank with a tiled outlet to the lake where the overflow effluent drains.

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.

Long Trade Lake (WBIC 2640500) was placed on the impaired waters list for total phosphorus in 2012 and for eutrophication caused by an unknown pollutant in 2014. The 2018 assessments showed continued impairment by phosphorus; new total phosphorus and chlorophyll-a sample data overwhelmingly exceeded the 2018 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. Chloride data did not exceed use thresholds. This water was not meeting its designated uses and was considered impaired. No listing change was needed to the existing impaired waters listing.

Long Trade Lake (2640500) was placed on the impaired waters list for total phosphorus in 2012 and for eutrophication caused by an unknown pollutant in 2014. The 2016 assessments showed continued impairment by phosphorus and eutrophication caused by an unknown pollutant; total phosphorus sample data overwhelmingly exceeded 2016 WisCALM listing thresholds for the Recreation use, but not Fish and Aquatic Life use, and chlorophyll data exceeded both REC and FAL thresholds. Based on the most updated information, no change in existing impaired waters listing is needed.

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.

Long 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.
