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

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

Watertown (population 21,420) is the largest city in the Upper Rock River Basin. The Rock River, which winds through Watertown, is the community's major water resource, providing numerous recreational opportunities. There are two small Federal Energy Regulatory Commission (FERC) licensed hydropower dams at Watertown. A 1994 water quality study conducted as part of the FERC relicensing process indicated that the upper dam had little impact on water quality (Hansis, 1995). However, flow reductions in the river resulting from hydropower operations at the Upper Watertown Dam may seriously threaten aquatic habitat. The slender madtom, a state endangered catfish species, is susceptible to flow reductions; its prime habitat is fast moving riffle areas.

An old coal gasification plant site exists in Watertown; little is known regarding potential threats to groundwater or surface water in the immediate area (WDNR, 1994)

Watertown has land use and facilities plans for the city's wastewater treatment plant service area. In 2001, the city began the process to develop a sewer service area plan pursuant to Chapter NR 121, Wisconsin Administrative Code. Such a plan would guide growth within Watertown's anticipated 20-year service area. The plan would identify areas for development and guide how that development will be staged over time to allow the most cost-effective expansion of sewer services. The plan would also identify environmentally sensitive areas such as wetlands, floodplains, stormwater conveyance and treatment areas, and other areas unsuitable for development or otherwise not to be developed (e.g., parks).

Watertown is experiencing development pressure largely due to its location approximately halfway between Madison and Milwaukee. No evaluation of construction site erosion problems or stormwater management has been conducted. Watertown should develop a comprehensive stormwater management plan in conjunction with current land use or long range development plans.

The City of Jefferson is at the juncture of the Crawfish and Rock rivers, which are regionally important recreational and aesthetic natural resources. The Jefferson wastewater treatment plant is addressing phosphorus reduction in its permit compliance schedule. A dam on the Rock River at Jefferson is obstructing fish migration. Studies have been conducted through the DNR and the US Corps of Engineers to assess installation of a fish passage at the dam.

The City of Fort Atkinson needs a sewer service plan to guide growth within its anticipated 20-year service area. Such a plan would identify areas for development and guide how that development will be staged over time. The plan would also identify environmentally sensitive areas such as wetlands, floodplains, stormwater conveyance and treatment areas, and other areas unsuitable for development or otherwise not to be developed (e.g., parks).

Historical Description

A large seepage and drainage fed stream originating in Fond du Lac, Dodge and Washington Counties. The Rock River enters Rock County at the foot of Lake Koshkonong, flows south through the center of the county, and into Illinois at Beloit. Four dams are located on the river in Rock County; Indianford Dam (6 foot head) located 6 miles below Lake Koshkonong, Janesville Central Dam (9 foot head) and Monterey Dam (9 foot head) located in Janesville, and Beloit Dam (10 foot head) located in Beloit. The 4 dams were originally constructed for hydroelectric power, but only the Janesville Central and Beloit Dams are still used for this purpose. The Indianford and Monterey Dams are maintained for recreation and flood control.

Flooding is a potential hazard along the Rock River. The river commonly rises 3-5 feet each spring, but has risen much higher and caused a great deal of damage. The greatest flood on record occurred in 1929 when a flood stage of 11.81 feet was reached at the U.S. Geological Survey stream gaging station at Afton. It is possible for floods of even greater magnitude to occur in any given year.

Pollution of the Rock River is not a new problem, but only in recent years have people become alarmed about the condition of this important water resource. At the present time an intensive pollution survey of the entire Rock River watershed is being jointly undertaken by State and Federal agencies. As sources of pollution are located, corrective steps will be taken.

The Rock River fishery is composed of a wide variety of species and is best described as multiple. The major sport fishery is made up of white basst crappiest catfisht northern pike, walleye and largemouth bass. Northern pike and walleye fishing is usually good below the dams in early spring. A large carp and sucker population is also present. Other species which appear in varying numbers include yellow percht smallmouth basst bluegillt buffalot redhorset longnose gart sheepsheadt bowfin and forage species. Most of the wetland along the river is associated with tributary streams and the description of these areas is included with the tributary description. There are about 100 additional acres of shallow marsh wet- land bordering the river. Waterfowl, predominantly woodduckst bluewing teal and American coott are commonly observed along the river during migratory periods.

Access to the Rock River is available from 14 bridge crossings and several roads which parallel and end at the river. In addition, there are eight boat launching ramps available for public use (indicated on Figure 9). There are also three marinas which rent boats and have launching facilities. There are 6 county parks which have a total river frontage of 2 miles.

Surface Acres -1,302, Miles = 35-.8, Gradient -1.2 feet per mile.

Impaired Waters

For assessment purposes the Rock River is broken into 8 segments. The Rock River Basin TMDL addresses phosphorus and sediment/TSS listings in the basin prior to 2011.

Rock River from State line to Janesville WWTP (miles 171.08 to 183.45) was put on the Impaired Waters List in the 1998 cycle for phosphorus, low dissolved oxygen, sediment, degraded habitat, and mercury and PCBs in fish tissue. The fish contaminants were removed from the list in the 2008 cycle. This segment of Rock River was evaluated every two-year cycle from 2012 to 2022; phosphorus data confirmed levels were too high. The TMDL plan for the Rock River Basin was approved in 2011. In the 2022 cycle bacteria data exceeded the new E. coli criteria.


Rock River from the Janesville WWTP to the US 14 bridge (miles 183.45 to 193.11) was put on the Impaired Waters List in the 1998 cycle for phosphorus, low dissolved oxygen, sediment, degraded habitat, and PCBs in fish tissue. The fish contaminants were removed from the list in the 2006 cycle. This segment of Rock River was evaluated every two-year cycle from 2012 to 2016; phosphorus data confirmed levels were too high.


Rock River from US 14 bridge near Janesville to Indianford dam (miles 193.11 to 201.29) was put on the Impaired Waters List in the 1998 cycle for phosphorus, low dissolved oxygen, sediment, degraded habitat, and PCBs in fish tissue. The fish contaminants were removed from the list in the 2006 cycle. This segment of Rock River was evaluated in 2012 and 2014; phosphorus data confirmed levels were too high.


Rock River from Indianford Dam to Lake Koshkonong outlet (miles 201.29 to 207.03) was put on the Impaired Waters List in the 1998 cycle for phosphorus, low dissolved oxygen, sediment, degraded habitat, and mercury and PCBs in fish tissue. The fish contaminants were removed from the list in the 2006 cycle.


Rock River from Lake Koshkonong inlet to Rock River Power & Light dam in Watertown (miles 207.32 to 242.84) was listed as impaired in 2002 for phosphorus. This segment of Rock River was evaluated every two-year cycle from 2012 to 2022; phosphorus levels were continuously elevated, reflected in poor biology (bugs and fish). Chloride levels were good.


Rock River from Rock River Power & Light dam in Watertown to confluence with the Ashippun River (miles 242.84 to 263.37) was placed on the impaired waters list in 1998 for degraded habitat due to total suspended solids. In 2006 phosphorus was added as a pollutant. This Rock River segment was evaluated in 2018 and 2022; chloride and fish data were in good condition. Phosphorus levels were still too high. Bacteria were evaluated in 2022; no impairment was found.


Rock River from Ashippun River to Sinnissippi Lake outlet (miles 263.37 to 286.97) was listed in 1998 due to a degraded habitat impairment caused by sediment/TSS, and total phosphorus was added as a pollutant in 2006. This segment of Rock River was evaluated every two-year cycle from 2012 to 2018; phosphorus levels were continuously elevated.


Rock River from Sinnissippi Lake inlet to confluence of South Branch and East Branch in Horicon Marsh (miles 296.46 to 298.64) was listed in 1998 due to a degraded habitat impairment caused by sediment/TSS, and total phosphorus was added as a pollutant in 2006. This segment of Rock River was evaluated every two-year cycle from 2012 to 2018; phosphorus levels were continuously elevated.

Impaired Waters

There are many lakes, rivers or streams in the Rock River Basin that are included on the 303(d) List. This effort is focused on those waters that are impaired by either excessive sediment, high phosphorus concentrations, or both sediment and phosphorus (see Table 1). These pollutants cause impacts to waterways which include low dissolved oxygen concentrations, degraded habitat, and excessive turbidity. All of these problems result in harm to fish and aquatic life, water quality, recreation and even navigation. Everyone who lives or recreates in the Rock River basin will benefit from the improved water quality that will result from reduced sediment and phosphorus.

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.

Project deliverables include: 1.) summary of water quality findings, 2.) compare concentration and loads of suspended sediments and nutrients between sites and data collected in 1998-2000. The data that is being collected will be used to compare with previous data. The water quality data, along with future biological data, will be used to determine if the impaired waters have improved and if so to an extent where the water bodies can be removed from the 303d list. 3.) Summary of implemented point and nonpoint practices. The project includes a tracking component using GIS mapping that tracks all practices implemented in the watershed. These maps, along with the data comparison information will show where practices have been installed and whether or not the project has been successful. 4.) The project includes an education effort to inform landowners and other stakeholders that the installation of ag nonpoint practices to reduce nutrient and sediment inputs to the Horicon marsh watershed does improve water quality and the quality of the River. The improved water quality data that is collected will be presented through various meetings and media to show that practices installed were successful.
Monitor Watershed (Status,Sources,Impairments)
The Rock River Coalition, Inc. will conduct a monitoring project on the Rock River to collect data and provide information to prove that the installation of conservation practices in the watershed resulted in improved water quality. Project deliverables include collecting and analyzing nutrient and suspended sediment samples from the two inlets and one outlet of the Horicon Marsh and sites in the East and West Rock River watersheds, compiling a list of point and nonpoint source practices installed since 2000, load computations for water year 2010, comparison on 2010 load computations with data previously collected data in 1998 and 1999 to see if improvements resulted from the practices installed, training additional citizen monitor volunteers (if necessary) to assist in the sample collection, and gathering information that will be useful in the implementation of the Total Maximum Daily Load (TMDL) of the Rock River.
Partnership Project
The Rock River Coalition, Inc., partnering with USGS, USFWS, the City of Horicon and WDNR will conduct a water quality monitoring project to determine if conservation practices installed since 2000 in the Upper Rock River Basin watershed has resulted in measureable improved water quality, provide a current baseline of water quality to assess changes occurring after 2009, foster citizen involvement and train citizen monitors in sample collection. The project will: 1) collect and analyze nutrient and sediment samples from two tributary streams and the outlet of Horicon Marsh; 2) compile an analysis of point and non-point source practices installed since 2000; 3) compare the new data to data collected in a similar study done in 1998 and 1999 to determine if water quality improvements have occurred. Along with a final report, project deliverables include: 1) an assessment of nutrient and sediment loading to the Horicon Marsh; 2) an assessment of effectiveness of point and non-point pollution reduction practices to reduce pollutant load to the marsh; and 3) provide data to help determine the accuracy of the TMDL modeling that will be done as part of the Rock River Basin TMDL project.

Standards Details

The Rock River is listed as impaired due to narrative water quality criteria exceedances that result in eutophication, excess algal growth, turbid conditions, and reductions in fish and aquatic life uses. These problems are caused by excess phosphorus in surface waters and excess sediment from runoff and soil erosion, which degrade conditions for aquatic life.

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.

Rock River is located in the Blackhawk Creek watershed which is 108.11 miĀ². Land use in the watershed is primarily agricultural (67.70%), suburban (11.60%) and a mix of urban (7.60%) and other uses (13.10%). This watershed has 94.55 stream miles, 96.88 lake acres and 415.15 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked Low 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.

Natural Community

Rock River is considered a Large River 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.
