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.
Default FAL
Fish and Aquatic Life - Default Waters do not have a specific use designation subcategory but are considered fishable, swimmable waters.

Overview

The Trempealeau River is 81 miles long and spans 3 counties. The Trempealeau River is a Class II brook and brown trout fishery for 15 miles above Lake Henry up to the confluence of the North and South branches, which includes the 11 mile stretch from CTH P near Taylor to Highway 95 in Hixton. Downstream from Lake Blair to CTH P near Taylor is a Class III trout water.

Historical Description

The Class II trout fishery was limited by NPS pollution associated with the agricultural land use of the watershed and the Badger Silica Mining operation. The section of the river downstream of Jonah Coulee Creek received high amounts of sediment in runoff from Badger Silica Mining.

Impaired Waters

Trempealeau River from confluence with the Mississippi to Main St. in Arcadia (miles 0 to 31.28) was put on the Impaired Waters List in the 2012 cycle for Mercury in fish tissue and in the 2012 cycle for high phosphorus levels. This segment was evaluated every two-year cycle from 2012 to 2022; phosphorus was consistently elevated.

Trempealeau River from Main St. in Arcadia to Lake Pigeon Creek in Whitehall (miles 31.28 to 51.72) was evaluated every two-year cycle from 2016 to 2022. In the 2018 cycle phosphorus levels were found to be too high and this river segment was put on the Impaired Waters List. In the 2022 cycle bacteria data were above the new E. coli criteria.

Trempealeau River from Pigeon River in Whitehall to Lake Henry dam in Blair (miles 51.72 to 61.32) was evaluated for biology and phosphorus in 2018 and this segment was listed for high phosphorus levels.

Trempealeau River from Lake Henry inlet to CTH P near Taylor (miles 61.98 to 69.85) was evaluated for biology and phosphorus in 2018 and this segment was listed for high phosphorus levels.

Trempealeau River from CTH P near Taylor to the confluence of the North and South branches near Hixton (miles 69.85 to 81.51) was evaluated for biology in 2014 and 2020; bug and fish communities were in good health. Phosphorus levels were too high and this segment was added to the impaired waters list in the 2018 cycle.

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
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.
Monitor and/or Protect Groundwater, Sourcewater
WDNR staff should continue to encourage communities to develop wellhead protection plans in the Watershed and the whole basin.
Nine Key Element Plan
Upper Trempealeau River PWS Plan - Nine Key Element Plan - The Upper Trempealeau River Priority Watershed Project plan assesses the nonpoint sources of pollution in the Upper Trempealeau River Watershed and guides the implementation of nonpoint source control measures. These control measures are needed to meet specific water resource objectives for the Upper Trempealeau 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 Upper Trempealeau River Priority Watershed Project area.

Blair should consider dam removal as a future management option in lieu of costly dam repairs and recurrent dredging, weighing the benefits of a streamside park against the cost of maintaining a millpond (Type C).

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

Trempealeau River is located in the Middle Trempealeau River watershed which is 205.47 mi². Land use in the watershed is primarily forest (38.50%), agricultural (31%) and a mix of grassland (21.40%) and other uses (9.00%). This watershed has 489.89 stream miles, 396.56 lake acres and 5,115.26 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked Not Available for runoff impacts on streams, Not Available 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

Trempealeau River is considered a Macroinvertebrate, Cool-Cold Headwater, Cool-Warm Mainstem, Coldwater 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.

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. Headwater species are abundant to common, mainstem species are common to absent, and river species are absent.
