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.
Yes

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.
Restricted Aquatic Life
Fish and Aquatic Life communities are not fully supported in this ecosystem.
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 Variance
Fish and Aquatic Life - Default Variance for DO and Pathogens. Waters do not have a specific use designation subcategory but are considered fishable, swimmable with the exception of their meeting water quality standards for dissolved oxygen and fecal coliform.

Overview

For assessment purposes the Menomonee River is segmented into five assessment units (AUs): from the mouth upstream to 35th Street (miles 0 to 2.67), from 35th Street to Honey Creek (miles 2.67 to 6.27), from Honey Creek to Little Menomonee River (miles 6.27 to 12.61), from Little Menomonee River to Willow Creek (miles 12.61 to 24.81), and from Willow Creek to the headwaters (miles 24.81 to 30.14).

As of the 2022 assessment cycle the first four segments (mouth to Willow Creek) are on the Impaired Waters List.

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.

TMDL Development
The Milwaukee Metropolitan Sewerage District proposes to develop third-party pathogen, phosphorus, and sediment TMDLs for the Menomonee River Watershed in Southeastern Wisconsin. The TMDLs will result in pollutant load and wasteload allocations that must be met to meet water quality standards and targets and in implementation plans that will identify the steps needed to achieve the load and wasteload allocations.
Fish Management, Access
Milwaukee Riverkeeper will provide and document education and outreach to municipalities, counties and landowners on fish passage impediments that need to be addressed in the Menomonee River Watershed through one on one meetings with phase 1 results, a list of fish passage impediments and GIS data presented. Additionally, Milwaukee Riverkeeper will recommend that all projects be routed through DNR for approval. Milwaukee Riverkeeper will document fish passage impediment projects addressed by government, repair/retrofits to existing structures, projects planned for future capital The DNR will be provided two paper copies and an electronic copy of the final report documenting projects by government to address fish passage impediments in the Menomonee River Watershed including the number of meetings, communications, materials developed, volunteers engaged and groups involved and grants submitted to deal with woody debris barriers.
Fish Management, Access
The project proposal is to identify and prioritize stream impediments for removal along the natural mainstream reaches of the Menomonee and Little Menomonee Rivers, including several major tributaries. This will be done by identifying and documenting barriers, analyzing impacts of each barrier, prioritizing barrier removals, educating/involving public, and working with local municipalities and counties to address impediments. The overall goal is to improve fish passage and public access. A GIS database will be developed to include, stream barrier locations, types and removal priority. A final report will be incorporated into a watershed restoration plan. Public outreach materials will also be created. The report and information will be shared with government agencies to make decisions on implementing best management practices to improve the targeted streams.
Water Quality Planning
Project: Menomonee River (MI03) Watershed Planning
Nine Key Element Plan
Menomonee River PWS Plan - Nine Key Element Plan - The Menomonee River Priority Watershed Project plan assesses the nonpoint sources of pollution in the Menomonee River Watershed and guides the implementation of nonpoint source control measures. These control measures are needed to meet specific water resource objectives for Menomonee River and its tributaries. The purpose of this project is to reduce the amount of pollutants originating from nonpoint sources that reach surface water and groundwater within the Menomonee River Priority Watershed Project area.

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

Menomonee River is located in the Menomonee River watershed which is 136.12 miĀ². Land use in the watershed is primarily suburban (34.50%), urban (32.70%) and a mix of agricultural (11.10%) and other uses (21.70%). This watershed has 174.17 stream miles, 352.64 lake acres and 5,967.40 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.

Natural Community

Menomonee River is considered a Cool-Warm Mainstem 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.
