Fish and Aquatic Life
Fishery Survey 1975 - Documented trout upstream of CTH DH which confirms its Class III classification. An updated classification from Class III to Class II for the upper 1.5 miles of Halfway Creek was recommended as a result of this survey.
Hydraulic and Sedimentation Study of Halfway Creek and Sand Lake Coulee Creek. Town of Onalaska, WI. November 1995, Vierbicher Associates Inc. EDA Project No: 06-06-61051. - Documented a substantial sediment load to Halfway Creek which originate in the lands that drain to Halfway Creek.

Halfway Creek, which flows through Holmen, is a twelve mile stream with portions classified as a Class II and III trout stream and a warm water sport fishery. Tremendous siltation from streambank pasturing has decreased in-stream habitat for fish and aquatic insects. Delivery of sediment from several tributaries also contributes to habitat problems seen in Halfway Creek. Streambank pasturing of livestock, barnyard runoff and cropland erosion are documented problems along Halfway Creek and its tributaries (Masterson). The stream has the potential to improve to Class I and II trout and extend the areas inhabited by trout water an additional two miles (Talley). The aquatic insect community above Holmen indicated very good to excellent water quality; however, excessive fecal contamination, suspended solids, and nutrients were also recorded (Masterson). Urbanization of the lower portion of this stream also contributes problems to Halfway Creek in the form of increased stormwater runoff volume and sedimentation from construction sites not secured with erosion control measures.
A cause of increased flood frequencies in the lower portions of Halfway Creek was linked to sediment loading throughout the 36 square mile Halfway Creek watershed. An estimated sediment load of 50,170 tons per year, or 1,400 tons/sq. mile/year, reaches Halfway Creek (Vierbicher). A portion of that sediment load is transported downstream. As the stream gradient decreases near the Mississippi River, movement of this sediment slows and accumulates in the stream channel, causing the stream to become wide and shallow, which leads to lower flood thresholds.
The Holmen wastewater treatment plant discharges to Halfway Creek. Adjustments in plant operation should be made that contribute to frequent treatment plant upsets. During the facility planning process, the community of Holmen should examine regionalized sewerage treatment with the City of LaCrosse as a potentially cost effective option (Cameron).
Metallics, Inc. discharges process wastewater to Halfway Creek. A study to determine water quality below the discharge in Halfway Creek was conducted in 1996. Continuous monitoring equipment measured a number of water quality parameters. No measurable impact to Halfway Creek with regard to temperature, dissolved oxygen or pH were documented (Sullivan and others).

Halfway Creek (Mouth to Main St. in Holmen (CTH DH)) was assessed during the 2018 listing cycle; new biological (macroinvertebrate Index of Biotic Integrity (IBI) scores) sample data were clearly below the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water was meeting this designated use and was not considered impaired.

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.

Halfway Creek is located in the Lower Black River watershed which is 189.82 mi². Land use in the watershed is primarily forest (35%), agricultural (34%) and a mix of wetland (12%) and other uses (19%). This watershed has 383.70 stream miles, 1,042.10 lake acres and 17,676.19 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.
