Fish and Aquatic Life
Spider Lake No.4, in the Brill and Red Cedar Rivers Watershed, is a 23.43 acre lake that falls in Washburn County. This lake is managed for fishing and swimming and is currently not considered impaired.

An irregular, crescent-shaped lake in the Spider Lake Chain. It is also a soft water, seepage lake and landlocked but with channels to No. 3 and No. 5 lakes. Its fishery is similar to the others with northern
pike, largemouth bass, perch, bluegills, black crappies, rock bass, pumpkinseeds, bullheads, white suckers and an occasional walleye. Water levels fluctuate more visibly in the lower lakes of the chain during dry years. The lake bottom is rather uneven with three basins evident along the lake's west shore. Aquatic vegetation is more common here with dense growths of watershield along shore and a marshy lake edge. The shorelands are upland with hardwoods and scattered pine. Two state-owned
islands of 0.7 and 0.2 acre are found towards the east end. The littoralzone bottom is mostly sand and gravel with boulders evident near the east end. The nesting ducks here include mallards, black ducks and wood ducks. Furbearer use is minor here. The lake has no private development. The main shoreline is Washburn County Forest land. Access is only by water from Spider Lake No. 5 or by walk-in over county lands.

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.

Spider Lake is located in the Brill and Red Cedar Rivers watershed which is 297.68 mi². Land use in the watershed is primarily forest (49.40%), agricultural (20.30%) and a mix of grassland (10.70%) and other uses (19.60%). This watershed has 264.90 stream miles, 6,282.34 lake acres and 15,832.05 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Medium 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.
