Trout Water 
Trout Waters are represented by Class I, Class II or Class III waters. These classes have specific ecological characteristics and management actions associated with them. For more information regarding Trout Classifications, see the Fisheries Trout Class Webpages.
No
Outstanding or Exceptional 
Wisconsin has designated many of the state's highest quality waters as Outstanding Resource Waters (ORWs) or Exceptional Resource Waters (ERWs). Waters designated as ORW or ERW are surface waters which provide outstanding recreational opportunities, support valuable fisheries and wildlife habitat, have good water quality, and are not significantly impacted by human activities. ORW and ERW status identifies waters that the State of Wisconsin has determined warrant additional protection from the effects of pollution. These designations are intended to meet federal Clean Water Act obligations requiring Wisconsin to adopt an 'antidegradation' policy that is designed to prevent any lowering of water quality - especially in those waters having significant ecological or cultural value.
No
Impaired Water 
A water is polluted or 'impaired' if it does not support full use by humans, wildlife, fish and other aquatic life and it is shown that one or more of the pollutant criteria are not met.
No

Fish and Aquatic Life

Current Use
The use the water currently supports. This is not a designation or classification; it is based on the current condition of the water. Information in this column is not designed for, and should not be used for, regulatory purposes.
Class III Trout
Streams capable of supporting a seasonal coldwater sport fishery and which may be managed as coldwater streams.
Attainable Use
The use that the investigator believes the water could achieve through managing "controllable" sources. Beaver dams, hydroelectric dams, low gradient streams, and naturally occurring low flows are generally not considered controllable. The attainable use may be the same as the current use or it may be higher.
FAL
Fish and Aquatic Life - waters that do not have a specific use designation subcategory assigned but which are considered fishable, swimmable waters.
Designated Use
This is the water classification legally recognized by NR102 and NR104, Wis. Adm. Code. The classification determines water quality criteria and effluent limits. Waters obtain designated uses through classification procedures.
Default FAL
Fish and Aquatic Life - Default Waters do not have a specific use designation subcategory but are considered fishable, swimmable waters.

Historical Description

Source: 1969, Surface Water Resources of Sawyer County Tiger Cat Flowage, T41N, R7W, Section 16

A soft water, drainage impoundment on the headwaters of the North Fork of the Chief River. The 12-foot head water control structure on the outlet also controls the levels of Upper and Lower Twin Lakes, Burns Lake, and Placid Lake. The estimated normal outlet flow is 8 cfs. The fish population of the flowage includes muskellunge, walleye, largemouth bass, smallmouth bass, perch, bluegill, pumpkinseed, and white suckers. Spider Creek also flows into Tiger Cat Flowage and it too has a warmwater fish habitat. Rooted aquatic vegetation growth is extensive, as are numerous bogs and conifer shrub swamp wetlands that border the flowage. Over 200 acres of these wetlands provide habitat for beaver, nesting ducks, and loon. There is one resort and boat rental, and five cottages. A county park at the dam has sites for camping and picnicking. The flowage is accessible from the public boat landing off the town road between the flowage and Lower Twin Lake. Public frontage consists of 0.3 miles of Sawyer County owned lakeshore frontage. Lower Twin Lake, T41N, R7W, Section 8 Surface Acres = 247.2, Maximum Depth = 30 feet, M.P.A. = 50 ppm, Secchi Disk = 11 feet A soft water, seepage lake with an inlet from Upper Twin Lake and an outlet to nearby Tiger Cat Flowage. The water controlstructure on the Tiger Cat Dam controls the level of the Twin Lakes. The fish population consists of muskellunge, walleyes, largemouth bass, smallmouth bass, and panfish. The lake has a considerable amount of submergent vegetation, and bog and shrub swamp shoreline providing extensive nesting habitat for ducks and loon. There are two resorts and boat rentals on the lake, and 17 cottages. The public access is located at the town road running between Lower Twin Lake and Tiger Cat Flowage. The town road right-of-way is the only public frontage. Upper Twin Lake, T41N, R7W, Section 5,6 Surface Acres = 298.5, Maximum Depth = 27 feet, M.P.A. = 44 ppm, Secchi Disk = 8 feet A soft water, drainage lake with an outlet channel meandering through a bog to Lower Twin Lake and the Tiger Cat Flowage. An inlet channel also connects this lake with nearby McClaine Lake. Water levels are controlled by the downstream Tiger Cat dam. The fish-population includes muskellunge, walleyes, largemouth bass, smallmouth bass, perch, bluegill, black crappie, rock bass, pumpkinseed, white sucker, redhorse, and common shiners. About 170 acres of wetlands of conifer bog shrub swamp and sedge meadow and extensive rooted aquatic vegetation in the lake provides nesting habitat for puddle and diving ducks and loon. Muskrats are also common. Private development on the lake amounts to five resorts, a boat rental, and seven cottages. The lake does not have a public access road, but is accessible by the outlet and inlet channels from connecting lakes. There is no public frontage.

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.

Reports

Recommendations

ATTAINS Water Identified for Protection
The Town of Spider Lake proposes to develop a Comprehensive Land Use Plan to guide the community in establishing the long range goals, Town ordinances, and the organization of Town Government and citizen groups to protect and enhance the quality of water in our lakes and the natural lake ecosystems.

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

Tiger Cat Flowage is located in the Lake Chippewa watershed which is 182.90 miĀ². Land use in the watershed is primarily forest (69.10%), open (16.50%) and a mix of wetland (12.70%) and other uses (1.60%). This watershed has 117.68 stream miles, 4,827.59 lake acres and 14,304.38 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked Low 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.

Natural Community

Tiger Cat Flowage is considered a Reservoir under the state's Natural Community Determinations.

Natural communities (stream and lake natural communities) represent model resultsand DNR staff valiation processes that confirm or update predicted conditions based on flow and temperature modeling from historic and current landscape features and related variables. Predicated flow and temperatures for waters are associated predicated fish assemblages (communities). Biologists evaluate the model results against current survey data to determine if the modeled results are corect and whether biological indicators show water quaity degradation. This analysis is a core component of the state's resource management framework. Wisconsin's Riverine Natural Communities.
