Fish and Aquatic Life
Overview
Watershed Management staff (WM) with the assistance of local conservation and fishing organizations, should improve habitat along the Crawfish River by installing habitat improvement structures (wing dams, tree drops, LUNKER structures, etc.) that increase depth and improve cover.
The Dodge County Land Conservation Department, with the assistance of WM staff and local conservation or fishing organizations, should reduce bank erosion along the Crawfish River by installing shoreline protection and by keeping cattle away from the stream.
WM staff should evaluate the feasibility of removing of the Danville dam on the Crawfish River should the dam partially or completely fail or be in need of major repairs.
WM staff should analyze northern pike, largemouth bass, and carp in the Crawfish River below Milford and from Mud Lake (Mud Lake is in UR03) for PCBs and mercury, and carp only for chlordane, dieldrin and DDT.

Overview
The Crawfish River below Columbus is wide, shallow and sluggish. The river was once narrower and deeper and supported stands of wild rice (WDNR, 1994). Primarily agricultural land use over the past 150 years has altered the river to its present condition. The stream partially supports a viable warm water sport fishery. The river's shallowness, bank erosion and lack of cover is suspected of limiting habitat for adult game fish in reaches that have been surveyed. Channel catfish and smallmouth bass dominate the sport fishery.
The reach immediately below the Danville dam has a diverse fish community and is ranked "good," using a 1989 Index of Biotic Integrity (IBI) (Kanehl and Lyons, 1989). However, a freshwater mussel study conducted in 1992 indicated that there was no viable mussel community in the Crawfish River below Danville. The loss of the mussels is due to the degraded system's poor water quality, which is also expressed by poor instream habitat, few minnows, and no reptiles, amphibians or waterfowl (WDNR, 1994). While a 1987 fish survey reported that the river's viable sport fishery could be improved by selective streambank and instream habitat restoration, the survey also suggested that removing the dam would improve instream habitat by narrowing and deepening the stream in its lower reaches (WDNR, 1994).
In 2000, comprehensive baseline monitoring was conducted by the DNR on the river. The results show that the evaluated section of the Crawfish River was in fair condition.
The City of Columbus is located about 25 miles northeast of Madison. Development pressures on the community, likely to increase over the next 10 years due to the city's proximity to Madison, contributes polluted runoff and reduces the quality and availability of habitat in the basin.
The Crawfish River and the Columbus Millpond are the primary water features. The Columbus wastewater treatment plant has experienced bypassing in 1998 due to unusually heavy rains.
The City of Lake Mills is on the east shore of Rock Lake in Jefferson County. The community and lake are under development pressure due to their proximity to Madison and Interstate 94. Construction site erosion problems have occurred. The Jefferson County LCD has been very active in working to improve construction site erosion control in the area. The community's wastewater treatment plant is in good operating condition.
Communities in the Crawfish River Watershed could further protect the Rock River by enacting and enforcing construction site erosion control and stormwater management ordinances, improving enforcement of existing construction site erosion control provisions, and acquiring parkland and natural areas adjacent the river and along drainageways leading to the river.

Historical Description
Crawfish River T10N, R12E, Section 12, Surface Acres = 85.5, Miles = 28.2, Gradient = 4.58 feet per mile.
Headquarters of a major stream of the Rock River watershed, this stream
flows first northeast, then southeast to drain much of eastern Columbia County.
There are two major tributaries, Robbins Creek and North Branch, Crawfish River.
Effects of impoundment at Columbus are felt more than a mile upstream. Bullheads,
crappies, smallmouth bass, northern pike and walleyes are present; however, the
fishery is primarily for northern pike. Buffalo, carp and suckers support an extensive
spring dip-net fishery. Carp and pollution are major use problems. Access
is possible at several county, town and state highway crossings. About 1,461 acres
of wetland adjoin the stream.

Impaired Waters
Crawfish River (829700) from Hwy 151 to its headwaters was placed on the impaired waters list for total phosphorus and sediment/total suspended solids in 2014. The 2016 assessments showed continued impairment by phosphorus; total phosphorus sample data exceeded 2016 WisCALM listing criteria for the Fish and Aquatic Life use, however, available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Based on the most updated information, no change in existing impaired waters listing is needed.

Impaired Waters
Crawfish River (Jefferson to Rock Creek) (WBIC 829700) was assessed during the 2016 listing cycle; total phosphorus sample data overwhelmingly exceed 2016 WisCALM listing thresholds for the Fish and Aquatic Life use, however, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category).

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.

Sewer Service Area Planning
The City of Beaver Dam water quality plan is developed as part of the water quality management plans for Dodge County as well as the Rock River basin.
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
Crawfish River is located in the Lower Crawfish River watershed which is 177.65 mi². Land use in the watershed is primarily agricultural (66.50%), grassland (11.20%) and a mix of wetland (10.70%) and other uses (11.60%). This watershed has 331.66 stream miles, 1,780.53 lake acres and 12,199.86 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low 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.
