Overview
The Yahara River is a large tributary to the Rock River, draining over 1/3 of Dane County. The river is nearly 40 miles in length with 23 miles in the Yahara-Kegonsa watershed. The stretch of the Yahara River in this watershed flows from the dam at Lake Waubesa and ends at the river s confluence with the Rock River. The river is slow-moving in most areas with an average gradient of 3.6 feet/mile and a baseflow of 68.8 cfs as it passes through the largely agricultural landscape.
The section of the Yahara that flows south from Lake Kegonsa was added to the 303(d) list in 1996. The 303(d) listed waters are those waters, which have impairment that prohibit them from meeting their potential use. Environmental problems have impacted the level of flow, habitat, fish migration, turbidity, dissolved oxygen, and sedimentation on the Yahara River. Efforts have been made over the past 20 years to reduce non-point and point source pollution. Despite these efforts, however, the Yahara River continues to be on the 303 (d) list of impaired waters. Fishkills, usually due to low dissolved oxygen, also continue to be a problem in the Yahara River below Lake Monona.
Although there is some point source pollution to the river, the greatest water quality problem in this stretch of the Yahara is from urban and rural non-point source pollution. Urban stormwater run-off carries sediment and pollutants to area surface waters. In addition, high development pressures in the region pose the threat of increasing construction site erosion. Since the majority of Dane County s population resides within the Yahara River Valley, development pressure on the Yahara system has been and continues to be intense. As the demand for waterfront property grows in the watershed, the lower Yahara River in particular will face increasing development pressure.
Rural sources of non-point pollution come from cropland erosion, pesticides, and runoff from barnyards and cattle exercise lots. Runoff from agricultural lands carries nutrients and sediment, which harm the aquatic habitat and water quality in the watershed. Sedimentation of the river and lake beds also increases turbidity of the water and decreases the amount of dissolved oxygen in the water.

Overview
The Yahara River originates in the marshy areas of Columbia County and flows as a small meandering creek through extensively farmed land to where it empties into the 2,000-plus acre Cherokee Marsh, and eventually Lake Mendota. Wetlands along this headwater stretch have been extensively drained, while small feeder streams have been straightened. The loss of wetlands combined with heavy agriculture in this reach have resulted in large sediment and nutrient loads and loss of valuable fish habitat. Heavy fertilizer use, poor animal waste management practices, and silage holding problems have reduced the river's water quality. A DCRPC report says the Yahara River carries the largest total mass of nutrients and sediments to Lake Mendota of the lake's five tributaries. Despite these loadings, the stream exhibits fair water quality and supports a good warm water sport fishery, as far upstream as DeForest. A monitoring station was reestablished on the Yahara River near Lake Windsor where flows were monitored from 1976 to 1980 and since 1989 and 1990 for monitoring for sediment, flow and phosphorus has continued. Development in DeForest and Windsor threatens water quality, in-stream habitat and fisheries of the Yahara River if adequate erosion control measures and post-development stormwater management are not established and maintained.
The Federal Emergency Management Agency (FEMA) is conducting floodplain studies in Dane County along Koshkonong Creek downstream of Sun Prairie and upstream of DeForest on the Yahara River. The possibility exists for similar work on Token Creek. Initial products include a digitized map of all floodplains in Dane County, to be incorporated into a Geographic Information System (GIS) database, and storm water quantity planning for a portion of Sun Prairie.

Overview
The Yahara River serves as relatively short connecting channel between lakes in this watershed. The segment between Lake Mendota and Lake Monona is adversely affected by sediments, debris and nutrients from Madison streets, parking lots and yards washing into the river and eventually to Lake Monona. As a “channel,” this segment receives tremendous boating pressure. Between Lake Monona and Upper Mud Lake, the Yahara has many of the same pollutant sources and exhibits the same poor water quality as in the Mendota-Monona segment.Rock River Water Quality Management Plan, Lower Rock River Appendix.

Overview
Stoughton has the only wastewater treatment plant that discharges directly to the Yahara River. Other point sources discharges include runoff from the railroad yards which is contaminated with oil, sulfur, and chloride; noncontact industrial cooling waters; and city swimming pool outflow.
Hydrologic modification to surface waters also negatively impacts water quality. The Yahara River has undergone only limited channelization projects, but its flow has been interrupted at many points by dams and locks built for navigation. Four dams occur on this reach of the river: at Lake Kegonsa’s outlet, Stoughton, Dunkirk and Stebbinsville. A fifth dam at Fulton has been removed. Hydrologic modifications, such as dams, can impair water quality by slowing flow, acting as sediment and nutrient collection basins, impeding fish movement, warming waters in the impoundment and, consequently, warming waters downstream.
Groundwater inputs are reduced and flows decline during dry periods due to the heavy pumping demands placed on the aquifer by the City of Madison and the diversion of sewage effluent around the Yahara lakes into Badfish Creek. The Madison Metropolitan Sewerage District (MMSD) began diverting flow around the Yahara Lakes in 1958. MMSD now provides advanced treatment and the current statutes would allow the DNR to evaluate a proposal to return the discharge to the upper lakes. See Surface Water Quality Issues for a more detailed discussion. Due to its proximity to ½ million people, the Yahara is heavily used for recreational purposes. The many parks along the Yahara River and the Stoughton lakeshores provide easy public access for hunting, fishing, canoeing and other recreation. In addition to its use for human activities, significant tracts of wetlands are particularly productive for waterfowl, especially the wetlands that lie between Lake Kegonsa and Stoughton.
The river also supports a diverse warm water sport fishery of approximately forty-eight species, containing most of the species common to the Madison lakes. Some areas of the river provide a rocky gravel substrate and good flow, making it an important spawning area for white bass and walleye. Crappie, sucker and northern pike also spawn in the river to some extent. Commonly found species include: northern pike, central stoneroller, common carp, golden, emerald, common and spottail shiner, bluntnose and fathead minnow, creek chub, buffalo (unsp.) white sucker, black, yellow, and brown bullheads, brook silverside, brook stickleback, white bass, pumpkinseed, bluegill, largemouth bass, white and black crappie, johnny darter, yellow perch, walleye, and mottled sculpin.

Historical Description
Yahara River -T5N, R11E, Sec. 35, Surface acres = 129, Length = 40 miles, Stream order = III, Gradient = 3.6 ft/mile,
Base discharge = 68.8 cfs.
The Yahara River is a large tributary to the Rock River which drains over 1/3 of Dane County. It originates in ColumbIa County and flows south, joining the Rock River in Rock County. It connects the county's four largest lakes--Mendota, Monona, Kegonsa, and Waubesa--whlch provide a wide range of recreational activities for a large percentage of the population of Dane County. Since the majority of the county's population resides within the Yahara River Valley, development pressure on the Yahara system has been and continues to be intense. Although large acreages of wetlands have been filled, drained or dredged, the Yahara Valley still encompasses some of the largest wetlands in the county due to their undrainable nature (Dane Cty. Reg. Plann. Comm. 1979a). The Yahara River has undergone only limited channelization projects, but its flow has been interrupted at many points by dams and locks built for flood control and navigation. Ground water inputs are reduced and flows decline during dry periods due to the heavy demands placed on the aquifer by the City of Madison and the passing of sewage effluent of the metropolitan area around the Madison lakes and into Badfish Creek.
In addition to these physical alterations of the river and its wetlands, municipal, industrial, and agricultural pollution have greatly affected the Yahara River. Prior to the 1950's all Madison area sewage effluent, usually treated but still high in nutrients, was discharged to the Madison lakes and the river. Currently all wastes are treated as efficiently as possible and are diverted around the lakes via Badfish Creek. Stoughton and Cottage Grove have the only treatment plants that discharge directly to the Yahara River. The only other point sources still remaining are runoff from the railroad yards which is polluted with oil, sulfur, and chloride; noncontact industrial cooling waters; and city swimming pool outflow (Dane Cty. Reg. Plann. Comm. 1979a). Nonpoint sources of pollution are runoff from agricultural and metropolitan areas and bank eroslon. The Yahara River is moderately fertile and only slightly alkaline, but chloride levels are quite high. Despite the reduction in pollution sources in the past 20 years, fishkills usually due to low dissolved oxygen have been a problem in the Yahara River, most often below Lake Monona.
The fishery is quite diverse, containing most of the species common to the Madison lakes along with occasional brown trout in the upper reaches. The river is also an important spawning area for white bass and walleye. There are many parks along the Yahara and the Madison lake shores, making public access very good. The Cherokee Marsh Fishery Area located north of Lake Mendota provides waterfowl, deer, pheasant, rabbit, and squirrel hunting. Muskrat and mink also inhabit the area.
Fish species: American eel, brown trout, northern pIke, central stoneroller, common carp, golden, emerald, common, and spot tail shiner, bluntnose and fathead minnow, creek chub, buffalo (unsp.), white sucker, black, yellow, and brown bullhead, brook sllverslde, brook stickleback, white bass, crappie (unsp.), pumpkinseed, blueglll, largemouth bass, white and black crappie, johnny darter, yellow perch, walleye, and mottled sculpin.

Historical Description
Surface Acres = 105.6, Miles = 8.5, Gradient = 4.7 feet per mile.
A large, sluggish river entering Rock County near Stebbinsville, then flowing southeast to enter the Rock River south of Indianford. Two dams are located on the stream in Rock County. The Fulton Dam forms Fulton Pond at Fulton and the other dam is at Stebbinsville. Both dams have a 14-foot head and are maintained for recreational purposes. The sport fishery is composed of black crappies, white bass, northern pike, bullheads and channel catfish. A high population of carp plus other warm water rough and forage species is also present. Pollution and excessive fertility are management problems. The Yahara River receives effluent from Stoughton; and Badfish Creek, which receives effluent from Madison and Oregon, enters the Yahara above Fulton Pond. According to a 1960 report by the Wisconsin Committee on Water Pollution, the effluent added to Badfish Creek had a marked effect on water quality of the Yahara River. Fertilizing nutrients (nitrogen, phosphorus) were greatly increased, which in turn, intensified algae blooms and made conditions more favorable for rough fish. Adjoining fresh meadow and timbered swamp lands totals 296 acres. The river and wetlands attract fair numbers of migrating waterfowl. Squirrels, deer and raccoon are also abundant in the unpopulated areas of the river bottom. The Yahara River also offers outstanding recreational opportunities for wildlife observation and canoeing. There is only one
boat launching ramp (located at Fulton Pond), but it is possible to launch canoes and small boats from one state highway and four town road crossings.

Educate and engage residents
The primary goals and objectives of this project are to use the resources obtained through this grant in a concurrent effort to educate, raise awareness and energize activists in the DeForest community so as to be ready to partner with other public units to attack the problems facing the Yahara River, and at the same time, enhance its public benefits.
Rivers Management Grant
Stoughton is proposing to improve its river environment, promote recreational and business activities on and along the river, and improve the communities' understanding of the economic value of the Yahara River. The primary goals and objectives of the river planning project will be to define demographic characteristics of the public users of the City's waterfront areas and ecologically sensitive improvements to these areas that promote use and also provide economic advantages for the City and its waterfront businesses. Another goal is to create a coordinated approach to protecting the river using existing river organizations.
Protect Riparian or Shorelands
The Village of DeForest will address the problem of erosion of Yahara River Streambank by hiring a consultant to assist with restoring the river's streambanks, creating a buffer zone throughout the river corridor, creating an ordinance to protect the buffer zone and river quality, and developing informational brochures to be distributed to the public regarding the Yahara River.
TMDL Implementation
The Rock River TMDL was approved by US EPA on September 28, 2011. Implementation planning is ongoing and sector teams are forming to address guidance and policy issues.
Sewer Service Area Planning
The City of Stoughton is requesting amendment to the Stoughton USA. The area is
located at the northwestern corner of the City, abutting Town of Dunn, Town of
Dunkirk, and Town of Rutland. The majority of the area is currently within the City.
Three town islands currently exist in the amendment area: a roughly 1.5-acre parcel
in the Town of Rutland and two parcels totaling around 14 acres in the Town of
Dunkirk. The amendment area is split in half by USH 51. Existing land use is
primarily agriculture, woodlands, other open lands, and single-family. Proposed land
use to the east of USH 51 includes large-scale multi-family and duplex residential,
open space/park, and stormwater management. Proposed uses immediately west of
USH 51 include commercial and stormwater management, while large and small-scale
multi-family residential, single-family residential, open space/park, and stormwater
management uses are proposed further west.
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.
