Natural Community
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.

Year Last Monitored
This is the most recent date of monitoring data stored in SWIMS. Additional surveys for fish and habitat may be available subsequent to this date.
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.
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.
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.

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.
Deep Seepage
Deep seepage lake describes the depth and hydrologic charactertistics of the lake. 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.
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.


Patrick Lake is a 50-acre mesotrophic/oligotrophic lake with good-to-very good water quality and good water clarity. Water clarity has decreased since 1983. Filamentous algae is common to abundant throughout Patrick Lake.

The Patrick Lake aquatic plant community colonized approximately three-quarters of the entire lake area to a maximum rooting depth of 13 feet. Within the important shallow water littoral zone, Patrick Lake, 100% of the sites were vegetated. The 0-1.5ft depth zone supported the most abundant aquatic plant growth. The aquatic plant community is characterized by high quality, good species diversity, an average sensitivity to disturbance and a condition closer than average to an undisturbed condition.

Patrick Lake is a 50-acre seepage lake in southeast Adams County, Wisconsin. Patrick Lake has a maximum depth of 21 feet and a mean depth of 10 feet.
Complaints about aquatic plant growth started in 1957. The first chemical treatments started in 1958, using arsenic, a very toxic substance that does not degrade, but remains in the sediments.

An assessment of the lake was conducted in 1978 by DNR staff due to complaints concerning plant growth. Najas spp, was the most abundant species. Myriophyllum spp., Potamogeton nodosus and P. richardsonii were common; Chara was present; Brasenia and Nymphaea occurred in one area.
At some point Eurasian watermilfoil was introduced into Patrick Lake; its introduction and spread may have been facilitated by broad spectrum treatments in the past that opened up areas for colonization of the exotic species. By 2004, Eurasian watermilfoil had colonized about 17-acres of the lake (Cason and Roost 2004) (Appendix IX). Herbicide treatments for controlling the Eurasian watermilfoil were conducted in spring 2005 (Table 1). The July 2005 survey did not find any Eurasian watermilfoil, but new colonies could resprout. A 0.5-acre area was found and treated in September 2005. Residents need to be watchful of new Eurasian watermilfoil colonies for several years.

Historical Description

Source: 1966, Surface Water Resources of Adams County Patrick Lake, T16N, R7E, Section 9 Surface Acres = 47.5, S.D.F.= 1.77, Maximum Depth = 10 feet.

A hard water seepage lake that has clear water, is alkaline, and has a moderate transparency. This lake has had periodicwinterkills but between times it is managed for northern pike, largemouth bass, and bluegills. An abundance of aquatic vegetation and a fluctuating, but generally declining water level are the major use problems. Public access, including an unimproved boat landing, is present. There are 18 dwellings and one youth camp located on the lake. Marl was reportedly removed from this lake many years ago. Waterfowl make use of the lake during spring and fall.

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.

Insufficient TP data to make assessment. Further TP monitoring recommended.
Lake Classification
Adams County proposes to wrap up its county-wide lake classification effort. Major project elements to include: 1) completion of water sampling, 2) development of lakes classification report and individual lake summaries, 3) development of a powerpoint presentation, 4) four public meetings, 5) expansion of shoreline restoration packet.
Lake Classification
Adams County continue its lake classification efforts through collecting and assessing chemical and biological data on all lakes within the county that afford public access. Major project componants to include: 1) collection and assessment of chemical and biological data, 2) development of a "library" of information for public use, 3) development of management recommendations, 4) I&E for riparians and lake users.
Lake Classification
Adams County proposes to initiate a Lakes Classification effort to assist in comprehensive plan development for communities surrounding its lakes with public access. Phase 1 elements, to be funded with this grant, include: 1) delination of surface watersheds and flow patterns, 2) delineation of ground watersheds, 3) identification and mapping of land uses, 4) inventory and mapping of shoreline erosion and development problems, 5) identification and mapping of sensitive/critical areas and natural heritage habitats, 6) verification of wetland delineations, 7) delineations of lake watersheds, 8) development of lake maps

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 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

Patrick Lake is located in the Neenah Creek watershed which is 173.35 miĀ². Land use in the watershed is primarily forest (38.20%), agricultural (30.80%) and a mix of wetland (14.80%) and other uses (16.20%). This watershed has 198.75 stream miles, 2,104.14 lake acres and 14,499.98 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked Not Available 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.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

Patrick Lake is considered a Deep Seepage 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.

Deep seepage lake describes the depth and hydrologic charactertistics of the lake. These variables affect the lakes response to watershed variables.
