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.
WWSF
Streams capable of supporting a warm waterdependent sport fishery. Representative aquatic life communities associated with these waters generally require cool or warm temperatures and concentrations of dissolved oxygen that do not drop below 5 mg/L.
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.
WWSF
Streams capable of supporting a warm waterdependent sport fishery. Representative aquatic life communities associated with these waters generally require cool or warm temperatures and concentrations of dissolved oxygen that do not drop below 5 mg/L.

Overview

The Big Eau Pleine River is classified as a warm water game fishery. The stream suffers from sedimentation and turbidity problems due to excessive run-off in the watershed. High bacteria counts at two county parks have forced swimming beaches to close. We have not determined the sources of the high bacteria, but potential sources include swimmers, septic systems, or animal waste. The Big Eau Pleine River is listed on the EPA 303 (d) list as an impaired waterbody for low dissolved oxygen and high levels of bacteria.

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

Citizen-Based Stream Monitoring
The Big Eau Pleine Citizens Organization (BEPCO) proposes to upgrade its web site and financial management system to improve its outreach and capacity to implement projects for the betterment of the Big Eau Pleine Reservoir in Marathon County.
Shoreland Ordinance
Marathon County proposes to amend or create a shoreland zoning ordinance that complies with the requirements of NR 115, Wisconsin Administrative Code (as revised effective February 1, 2010) and retain existing regulations that exceed the water resource protections of NR 115 or are specific or unique to local needs.
Water Quality Planning
The Big Eau Pleine Citizens Organization proposes to collect data on agricultural practices within the Fenwood Creek watershed and initiate a dialogue with farmers and rural property owners for the purpose of working to reduce polluted run-off to the Big Eau Pleine Flowage in Marathon County. Major project elements to include:a) water quality monitoring and analysis, b) outreach events.
Monitor or Propose 303(d) Listing
Big Eau Pleine River - 1427200. The Big Eau Pleine Flowage is identified as an Impaired waterbody on the 303 d list. The flowage is located in Marathon County and > 70% of the watershed landuse is agriculture. Nutrient and sediment loading from the watershed causes severe summer algae blooms and contributes to low dissolved oxygen levels in the winter.
Nine Key Element Plan
Lower Big Eau Pleine River PWS Plan -Nine Key Element Plan - The Lower Big Eau Pleine River Priority Watershed Project plan assesses the nonpoint sources of pollution in the Lower Big Eau Pleine River Watershed and guides the implementation of nonpoint source control measures. These control measures are needed to meet specific water resource objectives for Lower Big Eau Pleine 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 Lower Big Eau Pleine River Priority Watershed Project area. https://dnr.wi.gov/topic/nonpoint/documents/9kep/expired/LowerBigEauPleineRiver.pdf

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

Big Eau Pleine River is located in the Mosinee Flowage watershed which is 81.83 miĀ². Land use in the watershed is primarily forest (52%), wetland (15.30%) and a mix of agricultural (11.40%) and other uses (21.20%). This watershed has stream miles, lake acres and 7,457.82 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked Medium for runoff impacts on streams, Low 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

Big Eau Pleine 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.
