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

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.
Deep Lowland
Deep lowland lake describes the depth and location of the lake in a watershed. These variables affect the lakes response to watershed variables.
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.
Default FAL
Fish and Aquatic Life - Default Waters do not have a specific use designation subcategory but 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

Overview

Pike Lake is a 522-acre drainage lake in Washington County (WDNR, 1991). The lake is mesotrophic, bordering on eutrophic. It has an abundant aquatic plant population. Phosphorus loading from polluted runoff is a problem (WDNR, 1994). The lake has a good walleye fishery, but mercury has been found in some walleye and a fish consumption advisory exists for this species. The pugnose shiner, a fish on the Wisconsin Threatened species list and the least darter, a fish on the state's watch or concern list, have both been found in Pike Lake, a unit of the Kettle Moraine State Forest. The Pike Lake unit is on the northeast shore.

Historical Description

Source: 1963, Surface Water Resources of Washington County Pike Lake - T10N, R18E, Sec. 23,

A large, depression basin in the last drainage line of the Green Bay glacier. The lake is generally shallow with one deep basin, presumably the result of the presence of an ice block following glacial recession. Managed for panfish and walleye, with yellow perch the principle game fish. Carp are common to the shallow areas, but do not constitute a management problem. The Rubicon River both enters and leaves the lake on its north shore in a cattail, sedge marsh. About 40 per cent of the shore line is marsh associated, an estimated 180 acres of wetland adjoin the stream. Adequate public access for boat launching is provided by town roads ending on the west shore; however, parking is difficult, and public bathing and picnicking areas are not available. Parking is, in fact, prohibited by town ordinance. As part of the Outdoor Recreation Act Program, 1 192 acres adjoiningthis lake are to be acquired for a new state park. A fish refuge has been established on the channel above the dam and the Rubicon River below the dam for a distance of about 0.5 miles as protection for walleyes and northern pike during spawning runs. Hunting is permitted and the lake receives some pressure from nearby Hartford.

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.

Recommendations

Lake Classification
Phase 3 of Lake Classification Project. Public Hearing and Ordinance revision adoption for the lakes in Washington County. Dissemination of proposed ordinance changes to the other local units of government. Enforcement of revised zoning provisions related to shorelands, wetlands, and floodlands through current channels. Information to public of changes in Washington County codes by meetings, publicity, pamphlets, and brochures.
Lake Classification
Through this project Washington County will develop a waterbody classification system; review and revise shoreland-wetland and floodplain ordinances; and refine the ordinance provisions governing shorelands, wetlands and floodlands, incorporating the waterbody classification into them.

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

Pike Lake is located in the Rubicon River watershed which is 79.15 miĀ². Land use in the watershed is primarily agricultural (45.10%), grassland (19.90%) and a mix of wetland (13.40%) and other uses (21.60%). This watershed has 127.08 stream miles, 592.86 lake acres and 6,453.66 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked Medium for runoff impacts on streams, Not Ranked 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.This water is ranked High Lake for individual Lakes based on runoff problems and the likelihood of success from project implementation.

Natural Community

Pike Lake is considered a Deep Lowland under the state's Natural Community Determinations.

Natural communities (stream and lake natural communities) represent model results and 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.
