Fish and Aquatic Life
The Blue River rises in western Iowa County and flows west into Grant County before turning
north and flowing to the Wisconsin River. The lower 18 miles of the river support a warm
water sport fishery. Approximately 13.8 miles of the stream above the warm water sport
fishery is a Class II trout fishery with some natural reproduction of brown trout. The trout
waters reach of the Blue River is considered an exceptional resource water, (ERW), and is
considered a high priority for nonpoint source pollution reduction. A cursory habitat
evaluation was done on a tributary to the Blue River in the summer of 2001. This survey
found fair habitat and overall problems resulted from erosion and nonpoint source pollution
from the watershed.
The intensive agriculture in the watershed is a limiting factor. Barnyards and grazing may be
causing in-stream habitat and water quality problems in the reach above the state fishery area.
Eroding streambanks are also a problem in spots, and silt deposits in some pools and riffles
are causing in-stream habitat problems. The headwaters of the Blue River have some
problems with feedlots and are on the list of "impaired waters" due to nonpoint source
pollution. The Blue River receives discharges from the villages of Blue River and Montfort.
The state has easements along much of the river in the headwater area of the river.
Citizen monitors have been actively monitoring the Blue River since June 2000. A second
monitoring site on the river was added in August 2001. Volunteers regularly monitor the
turbidity, temperature, dissolved oxygen, and flow of the river. Additional monitoring items
include an assessment of the biological aquatic bug community and the in-stream habitat of
the river. To see the data that these monitors have collected, please visit their website at

The Blue River rises in western Iowa County and Rows west into Grant County before turning north and flowing to the Wisconsin River. About 13.8 miles of the stream are Class II trout waters (WDNR. 1980). The trout waters reach of the Blue are considered exceptional resource waters. Barnyards and grazing may be causing in-stream habitat and water quality problems in the reach above the state fishery area (Kerr,WDNR,1991, Schlesser 1991-1992). Eroding streambanks are also a problems in spots, and silt deposits in some pools and riffles are causing in-stream habitat problems (Kerr, 1991).

From: Smith, Tom D., and Ball, Joseph R., Lake and Stream Classification Project. Surface Water Resources of Grant County, Department of Natural Resources, 1972.Surface Area = 30.31 acres, Length = 25.0 miles, Gradient = 8 ft./mile, Flow = 51.5 c.f.s.
A spring- and seepage-fed stream beginning in Iowa County as "Foreman Creek" and flowing southwest to empty into the Wisconsin River northeast of the village of Blue River. The regional land form of this water- shed is early maturity or late youth with narrow ridges, remnants of flat uplands, and steep, narrow valleys. The floodplain is one-fourth to one mile in width along the main section of the river. The terrain resembles the rimrock country in Montana and Wyoming with evergreen-capped outcrops overlooking much of the stream.
The Blue River also has quality trout fishing as well as spectacular scenery. Numerous springs and spring-fed tributaries contribute to the stream assuring favorable temperatures and a stable water supply. Eight of these tributaries are classified as trout streams with Fennimore Fork rated as the best trout water in Grant County. The upper 3.5 miles of the Blue River is considered trout water. This could be extended downstream to include everything above the mouth of Big Rock Branch. Brown and rainbow trout dominat~ the fishery in this section of stream. Brook trout are also present. A good catfish and smallmouth bass fishery exists in the lower reaches near the Village of Blue River. Trout reproduction is low due to large rubble and rapid runoff. Fishing pressure is heavy during much of the season. The Blue River P.L. 566 Watershed Project was organized in order to reduce some of the flash flooding and heavy bank erosion within the watershed. Eight
or nine single-purpose structures and one multi-purpose structure are scheduled to be constructed. Onlyone of these structures is planned on the main stem of the Blue River.
The villages of Montfort and Blue River are potential pollution sources. Game assets include muskrats, a few migratory waterfowl, mink, beaver, raccoon, squirrels, red and gray fox, deer, and ruffed grouse. A total 672 acres of shallow marsh, fresh meadow and timber swamp wetland adjoin the lower reaches. Public access is provided by the Wisconsin River, ten bridge crossings and 1.75 miles of stream easement. Fifteen farm dwellings are found along the banks.

Flowing northwesterly into Grant County and then northerly into the Wisconsin River, this spring fed and moderately swift flowing stream possesses a well-rounded sport fishery. Although flooding and erosion problems are common to its upper sections, primarily because of intensive farming practices, brown and natural brook trout populations are present. Smallmouth bass, catfish and northern pike are present near its mouth in Grant County. Forage fish species found in the upper sections include sculpins, blacknose dace, redbelly dace, common shiner, fantail and johnny darters, blunthose minnows and white suckers.

Blue River (1211000) its mouth to Biba Rd. was placed on the impaired waters list for total phosphorus in 2012. The 2016 assessments showed continued impairment by phosphorus; total phosphorus sample data exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use, however, no biological data (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) were available to assess biological impairment. Based on the most updated information, no change in existing impaired waters listing is needed.

Blue River (1211000), from Unnamed Stream (1214100) to its headwaters, was placed on the impaired waters list for sediment/total suspended solids in 1998.

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 2016 . See also 'monitoring' and 'projects'.

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 and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.
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.

Blue River is located in the Blue River watershed which is 216.19 mi². Land use in the watershed is primarily agricultural (51%), forest (37%) and a mix of suburban (5%) and other uses (6%). This watershed has 513.46 stream miles, 416.83 lake acres and 5,825.06 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Ranked 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.
