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

Overview

Rock River Water Quality Management Plan, Lower Rock River Appendix. WT-668-2002. South Central Region, WDNR.

Gibbs Lake is a small, hard water, drainage lake in Rock County, which drains through Gibbs Creek to the Yahara River. It has a surface area of 72 acres and a maximum depth of 20 feet. A popular county park surrounds two-thirds of the lake. A small dam was constructed in the 1960’s to control water levels and prevent the downstream movement of northern pike. The pike traveled downstream (instead of upstream) to spawn on a wetland area. The wetland often dried up and farmers would illegally harvest the fish with pitchforks. In the past, the lake was used by migrating and nesting waterfowl. The dam continues to hold the lake at a higher than normal level (about two feet) and prevents the unintentional downstream migration of northern pike.
Today, it has extensive vegetation with a large population of panfish. Extensive nutrient loads from non-point source pollution have caused occasional winterkill, nuisance aquatic growth and algae problems. Eurasian watermilfoil dominates the lake and water clarity is poor. The lake was the site of littoral zone research focusing on Eurasian watermilfoil. Secchi disk readings during 1986 indicated poor to very poor water clarity. Secchi disk readings from 1988 indicated good water clarity. One possible explanation for the differences between the readings is the lower rainfall, particularly in the spring of 1988, which may have reduced sediment and nutrients entering the lake. Agricultural runoff from the two-square-mile drainage area also affects the lake's water quality. Local interest in lake management and control of polluted runoff is high. Efforts to control soil erosion in this watershed should be made a priority. This lake would benefit from the identification of sources of polluted runoff and excess stormwater and the implementation of best management practices.
Controls have been imposed in an attempt to increase the fishery health of the lake. A weed-cutting project conducted by the University of Wisconsin served to cut predator lanes through the weedy patches. This increased panfish predation has helped to raise the overall size of bluegill by decreasing population pressure. This was effective only in the short term and was discontinued due to the high expense. A size limit for bass was also imposed, thereby increasing predators. In addition, walleye, northern pike and northern catfish have been stocked in this lake.
Agricultural runoff in this portion of the watershed affects the Gibbs Lake fishery. Siltation has caused loss of habitat and rough fish populations are a problem. Gibbs Lake is a panfish fishery and commonly found species include northern pike, common carp, golden shiner, white sucker, black bullhead, yellow bullhead, brown bullhead, green sunfish, pumpkinseed, bluegill, largemouth bass, yellow perch, walleye, black crappie. Access to the lake can be gained via Gibbs Lake Park.

Overview

The wetland area between Little Gibbs Lake and Gibbs Lake primarily shrub carr with some areas of wet meadows. The primary vegetation is cattails, reed canary grass and red-osier dogwood. The presence of reed canary grass is an indicator of disturbed wetland areas. Little detailed information is available on these wetlands. Gibbs Lake Park encompasses the wetlands between the lakes and around Gibbs Lake and improved information may interest the park’s visitors.

Historical Description

Source: 1970, Surface Water Resources of Rock County Gibbs Lake, T4N, R11E, Section 27

A hard water, drainage fed, natural lake connected to lake 34-5 (sometimes called Lower Gibbs Lake) by a small stream. The water level of Gibbs Lake is controlled by a low head dam at the outlet, which is the headwater of Gibbs Creek. The fish population was chemically eradicated in the summer of 1968 and the lake was restocked at a later time. Gibbs Lake should offer an excellent fishery in the near future. Shoreline development includes 1 boat rental and 11 dwellings. Unimproved public access is provided by a county park which includes two-thirds of the shoreline. The lake is commonly used by migrating and nesting waterfowl and there are no restrictions on hunting other than local ordinance.

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.

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.

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

Gibbs Lake (Big Springs) is considered a Deep Headwater 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.
