Overview

Trude Lake is a soft water drained lake having slightly alkaline, light brown water of moderate transparency. The outlet is tributary to the Flambeau Flowage. A water control structure is located on the outlet having a head of approximately 6 feet. Sand is the predominant littoral material (60 percent) with muck (20 percent), gravel (10 percent) and rubble. The shoreline is predominantly upland (95 percent) with the balance being wetland of the meadow type. Muskellunge, northern pike, walleye, largemouth bass, perch, bluegill, black crappie, rock bass, pumpkinseed, bullhead, white sucker, and redhorse inhabit this lake. waterfowl, including Canada geese, utilize this lake on their migrations. Nesting waterfowl in all probability make some use of this area. Floating, emergent and submergent plants are moderate in density in various parts of the lake basin. There are six dwellings, one resort and a girls' camp located on the shoreline. Public access from a town road, crossing the outlet, is available with very limited parking and an unimproved facility. Water levels of Trude Lake are contingent upon levels maintained in the Flambeau Flowage; thus, regulation of the dam at the outlet is necessary to maintain satisfactory water levels in this lake. A temperature profile taken on July 8, 1963 revealed a temperature range of 73 degrees Fahrenheit at the surface to 49 degrees Fahrenheit at the bottom. The upper thermocline occurred at 12 feet.

Natural communities (stream and lake natural communities) represent model results that use predicted flow and temperature based on landscape features and related assumptions. Ranges of flow and temperature associated with specific aquatic life communities (fish, macroinvertebrates) help biologists identify appropriate resource management goals.

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.
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.
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.
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.
Deep lowland lake describes the depth and location of the lake in a watershed. These variables affect the lakes response to watershed variables.
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.
Streams capable of supporting a warm waterdependent sport fishery. Representative aquatic life communities associated with these waters generally require cool or warm temperatures and concentrations of dissolved oxygen that do not drop below 5 mg/L.
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.
Fish and Aquatic Life - Default Waters do not have a specific use designation subcategory but are considered fishable, swimmable waters.
