Fish and Aquatic Life
The Hay River, along with the Red Cedar River, are large rivers that drain into Tainter Lake. Both
rivers contribute nutrients to Tainter Lake, whch experiences frequent algal blooms. In an attempt
to quantify nutrient loads to the lake, the Hay River was sampled for phosphorus, suspended solids,
and stream flow from October, 1989, to September, 1990, by the U.S Geological Survey. Numerous
water quality samples were also collected from wastewater treatment plant discharges on the Hay
An estimated 700,000 pounds of phosphorus was delivered to Tainter Lake by both the Hay and
Red Cedar Rivers. The Hay River contributed about 30 percent of the total, or 210,000 pounds. Of
that, about 12 percent was attributed to point source discharges, primarily wastewater treatment
plants, and the balance is assumed to be from nonpoint sources. About 94 percent of thls
phosphorus load is thought to be controllable (Schreiber).
The Cumberland wastewater treatment plant discharges to the headwaters of the Hay-River
downstream of the dam forming Beaver Dam Lake. This rotating biological contactor plant
discharges more than 150 pounds of phosphorus per month, and must provide phosphorus removal
under NR 217 of the Wis. Adm. Code. The present permit requires construction of phosphorus
removal facilities and sludge storage, as well as whole effluent toxicity testing.
Stella Cheese operates a cheese factory and whey drying plant south of Almena. An aerated lagoon
and spray irrigation system treats process wastewater. Steam, whey condensate, and non-contact
cooling water are discharged to an unnamed tributary to the Hay River. Past testing has shown
this discharge to be potentially toxic to aquatic life. Follow-up testing is ongoing, and the reissued
permit should address whole effluent toxicity in this discharge. WDNR is also conducting a study
on this and similar discharges to identify the causes of the toxicity.

The 2018 assessments of the Hay River (Mouth to CTH F) showed continued impairment by phosphorus; new total phosphorus sample data exceeded the 2018 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 the existing impaired waters listing was needed.

Hay River (2068600) from its mouth to CTH F was placed on the impaired waters list for total phosphorus in 2012 and the portion from Cth F to 20th Ave was listed for total phosphorus in 2014. The 2016 assessments showed continued impairment by phosphorus for both of these portions of the Hay River; 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.

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.
Dunn 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.

Nine Key Element Plan
Hay River PWS Plan - Nine Key Element Plan - The WI Nonpoint Source Water Pollution Abatement Program was developed to address water quality programs and to implement technical and institutional solutions delineated in the area wide plan. The Hay River Watershed was selected as one of the first five priority watersheds.
Monitor Water Quality or Sediment
incorrect IBI applied to the sites. Verified the natural community. Sites are headwater not main stem. IBIs are fair and good.
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 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.

Hay River is located in the Wilson Creek watershed which is 244.75 mi². Land use in the watershed is primarily agricultural (37.50%), forest (31.40%) and a mix of grassland (19.40%) and other uses (11.70%). This watershed has 425.11 stream miles, 1,332.74 lake acres and 5,388.38 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, High 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.
