Quas Creek, in the East and West Branches Milwaukee River Watershed, is a 6.25 mile river that falls in Washington County. This river is managed for fishing and swimming and is currently not considered impaired.

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.
Citizen-Based Stream Monitoring
Collect chemical, physical, and/or biological water quality data to assess the current overall stream health. The data can inform management decisions and may be used to identify impaired waters for biennial lists.
Educate and engage residents
Washington County will assist in development of a new river organization. Funds will lead the effort to create a private, non-profit Quaas Creek Watershed Protection Group, either as a stand-alone entity or by expanding an existing non-profit group. Information and education efforts for pollution control and land use planning in the watershed will be the primary focus. Scope change 9/17/02: The Washington County Land Conservation Dept. will coordinate the implementation of a Quass Creek Watershed Education Program. This education program is part of a larger Watershed Protection Plan being developed by an intergovernmental committee called the Quass Creek Watershed Protection Committee. Information and education efforts for pollution control and land use planning in the watershed will be the primary focus. As a result of the project and its success, Washington Co. will assist in the development of a new river organization.. Funds will lead the effort to create a private, non-profit Quass Creek Watershed Protection Group, either as a stand-alone entity or by expanding an existing non-profit group.
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.

Quas Creek is located in the East and West Branches Milwaukee River watershed which is 266.00 mi². Land use in the watershed is primarily agricultural (35.50%), wetland (19.20%) and a mix of forest (17.90%) and other uses (27.40%). This watershed has 312.44 stream miles, 2,023.13 lake acres and 32,107.47 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, High 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.
Quas Creek is considered a Cool-Cold Headwater, Cool-Warm 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.
Cool (Warm-Transition) Headwaters are small, sometimes intermittent streams with cool to warm summer temperatures. Coldwater fishes are uncommon to absent, transitional fishes are abundant to common, and warm water fishes are common to uncommon. Headwater species are abundant to common, mainstem species are common to absent, and river species are absent.
Cool (Cold-Transition) Headwaters are small, usually perennial streams with cold to cool summer temperatures. Coldwater fishes are common to uncommon (<10 per 100 m), transitional fishes are abundant to common, and warm water fishes are uncommon to absent.
