Trout Water 
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.

Overview

The East Branch of the Pecatonica River has its headwaters between Barneveld and Blue Mounds. Both villages discharge wastewater to the East Branch. The river flows thirty two miles down to the town of Blanchardville and is navigable for most of its length. The river has four miles of classified trout waters, but the majority of the river in this watershed is a warm water sport fishery. The gradient is fairly low in comparison to other streams in the area provides holes and areas of deep, slow moving water. Walleye, smallmouth bass, channel catfish, and northern pike are found in the river. Walleye stocking appears to have been successful with larger numbers of walleyes being caught by anglers (Sims, pers. comm).

The rapid runoff of precipitation in this predominantly agricultural watershed causes problems with regard to habitat, turbidity, and nutrient load. Woody debris presents a problem to navigation. Additionally, the dam at Blanchardville impedes fish movement upstream.

Overview

Nearly 37 miles of the West Branch of the Pecatonica River is contained in this watershed. The fish manager reports that this portion of the river is degrading, most likely due to manure and runoff from barnyards. Netting surveys conducted in 2001 showed that the upper end does not support walleye, smallmouth bass, or channel catfish even though the habitat is favorable. For more details on the Pecatonica River as a whole, see the focused watershed narrative on page number.

Twenty three miles of the river flows through LOWER PECATONICA RIVER WATERSHED. See the Pecatonica River Mainstem write up for more information.

Historical Description

The West Branch of the Pecatonica River is a warmwater seepage stream which, although it does not have the largest base discharge, does have the largest watershed in the county. It begins on the vale of the cuesta (Military Ridge) of the Galena-Black River Uplands and flows southerly into Lafayette County where it joins the East Branch and the Pecatonica River proper is formed. Principal tributaries in Iowa County are Livingston Branch and Williams Creek.

These contribute about 50 percent to its base flow in Iowa County. A stream system which begins in Iowa County but enters in Lafayette County is the Mineral Point Branch which drains about 98 square miles and has a base flow of about 8.7 cfs when it leaves the county. Heavy bank erosion is a common feature throughout its length. This is partly a result of the intensive use of the watershed lands for agricultural purposes. About 94 percent of the land is open land used mainly for crops and pasture. Three possible sources of pollution on the mainstream are the Cobb Sewage Treatment Plant, a cannery and a cheese factory. Their effluent is closely monitored by the Division of Environmental Protection. There is evidence that the canning company has been an intermittent source of pollution and has been the cause of fish mortalities in the past. The principal sport fishery throughout the watershed is smallmouth bass which varies from common to abundant. Channel catfish are also found in the lower sections. Forage fishes are abundant and include the following species; bluntnose, fathead and stoneroller minnows; common, rosyface and bigmouth shiners; hornyhead and creek chubs; hog and white suckers; redbelly dace and johnny darters. Panfish that are known include orange-spotted sunfish, green sunfish and black bullheads. Aquatic game assets include muskrats throughout most of its length and some migratory waterfowl. There are no public lands along its bank but it is accessible from eight road crossings.

Historical Description

The Pecatonica River is formed by the joining of its East and West Branches about two miles east of the town of South Wayne. Although it leaves the county shortly after it comes into existence, it is by far the largest stream in
Lafayette County. It drains about 74.3 percent of the county's total land area, and 49.3 percent of its total watershed area in Wisconsin lies in Lafayette County. Of the Peca:tonica's watershed area within the county, 39.7 percent drains into the East Branch and its balance drains into the West BranCh. The Pecatonica flows through Green County into Illinois and the Rock River, down to the Mississippi. Within Lafayette County, the principal fishery is smallmouth bass, channel and flathead catfish, and walleyes. Farther downstream, in Illinois, there is a small commercial fishery for the latter three species. Northern pike are also present. Game assets include a sizeable muskrat population and large numbers of puddle ducks in the spring and all. The watershed in general also contains upland species common to the county. Public access within the county is provided from unimproved access points on its East and West Branches near the municipality of South Wayne.

Impaired Waters

The 2018 assessments of the Pecatonica River 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.

Impaired Waters

Pecatonica River (889100) was placed on the impaired waters list in 2014 for total phosphorus. 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, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). This water was also assessed for chlorides and sample data did not exceed 2016 WisCALM chronic and acute listing criteria for the Fish and Aquatic Life use. Based on the most updated information, no change in existing impaired waters listing is needed.

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.

Monitor or Assess Watershed Condition
Conduct a comprehensive review of waters in watershed to update the watershed plan, stream narratives (if possible) and to gather background information on Silver Spring as a "pre-Phosphorus index"  project look-see.

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.
