Fish and Aquatic Life
Upper Mud Lake This shallow, fertile 256-acre lake between Lakes Monona and Waubesa, Upper Mud is entirely surrounded by 1,000 acres of wetlands. In fact, the lake was formed by a railroad grade crossing a marsh at the inlet of the Yahara River to Lake Waubesa. The wetlands provide good spawning areas for northern pike in the Monona-Waubesa lakes and an excellent stopover for migratory waterfowl. The lake's watershed is 11.5 square miles, and contains portions of the town of Blooming Grove and the cities of Monona and Madison. Increased polluted runoff from new development is a concern that should be addressed.
One perennial stream (Penitto Creek) exists in this subwatershed. Past monitoring on the stream has identified the presence of Gammarus sp. indicating groundwater seepage and “very good” water quality based on a biotic index classification system (Marshall, 1990). a project to remove sediments and stabilize Penitto Creek is underway.
Dredging of wetlands associated with the construction of the South Beltline Highway in Monona and Madison altered Upper Mud Lake's fish habitat. A 25-acre wetland restoration project to mitigate wetlands lost or destroyed by the beltline project has been completed in the lake's watershed. Very good fishing has been reported in some of the deep holes left by the dredging.
Boat traffic through Upper and Lower Mud lakes between Lakes Waubesa and Monona is heavy during the entire open water season. Wetlands of Upper Mud Lake are negatively affected by fast boat traffic through the open water areas. Fast boat traffic degrades established wetland vegetation and stirs the lake's sediment which reduces water clarity and inhibits the establishment of wetland plants. Fewer wetland plants means fewer nutrients taken up by aquatic plants, and thus, more phosphorus and nitrogen are available for use by algae. The stirring of bottom sediment and degradation of wetland plants by boat traffic is a serious water quality issue that should be addressed. The Dane County Lakes and Watershed Commission worked to pass a proposal for a “no wake” zone on all Madison waterbodies within 200 feet of the shoreline. This proposal should be implemented as it would protect existing vegetation, reduce accidents and hazards in nearshore areas, reduce shoreline erosion, and maintain or help improve water quality.
A pothole wetland located near the northeast corner of the intersection of Vondron and Femrite Roads was identified as a high quality wetland by the 1990 UW-Water Resource Management Workshop. Migratory waterfowl make use of the lake and its wetlands in spring and fall. Because of its location between Monona and Waubesa, the fish consumption advisory should probably be observed on this lake as well.
In the stretch of the Yahara River connecting Upper Mud Lake to Lake Waubesa, which is located in the town of Dunn, archaeologists have identified the “Dyreson Fish Weir,” a structure constructed by prehistoric Native Americans that may be associated with a mound-building culture known to exist on the adjacent banks at one time. This site is currently being nominated for inclusion on the National Register of Historic Places and is only one of 10 known ancient fish weirs in the state.

This wetland complex lies on either side of Upper Mud Lake between Lakes Waubesa and Monona. Portions of the original marsh have been filled in for development or have been otherwise disturbed by urban activities; other parts show evidence of past attempts to drain it. In the late 1980s the Wisconsin Department of Transportation (DOT) built a six-lane highway through a portion of the marsh to ease traffic congestion. The construction resulted in some wetland destruction, but other wetland areas were restored (about 25 acres) or created to compensate for the areas lost. Studies have shown, however, that the type of wetland lost, primarily wet meadow, have been replaced or mitigated with deep water marsh. These different habitat types support different wetland plants and perform somewhat different functions.
The Upper Mud Lake wetlands complex is diverse, ranging from shallow marsh with large monotypic cattail stands, to disturbed wet meadows with shrub willow stands. The large monotypic cattail stands may not provide adequate spawning areas for northern pike. A number of waterfowl/wildlife ponds were constructed as part of DOT mitigation to increase habitat diversity. Some of these ponds have been adversely affected by polluted urban runoff. The most serious threat to wetland water quality in the Upper Mud Lake complex is from construction site erosion and urban stormwater runoff from the South Beltline and the city of Monona.

This shallow, fertile lake was formed by a railroad grade crossing the marsh at the inlet of the Yahara River to Lake Waubesa. The lake is entirely surrounded by timber marsh, shallow marsh, and wet meadow and provides excellent spawning habitat for game fishes. Migrating waterfowl frequent the lake. The Yahara River is thesource of a large, constant flow of nutrients into the lake. Water quality is poor and aquatic vegetation is dense, limiting recreational potential. Upper Mud Lake supports a good fishery for game fish found in the Yahara River system and receives moderate use. Wilderness type access is available through state-owned lands on the eastern shore and through a county park on the western shore. Boats have access through the Yahara River from Lakes Monona and Waubesa. Fish species: longnose gar, bowfin, northern pike, common carp, golden shiner, bluntnose and fathead minnow, white sucker, black, brown, and yellow bullhead, channel catfish, brook silverside, white and rock bass, green sunfish, pumpkinseed, bluegill, largemouth bass, white and black crappie, yellow perch, walleye, and freshwater drum.

ATTAINS Water Identified for Protection
Dane County Lake Classification-Phase 2: The Phase 1 classification grant classified all county lakes and streams. This grant will take the next step by developing a management program based on the classification.
ATTAINS Water Identified for Protection
Dane County Department of Planning and Development will hire a project staff in order to develop a Lake Classification project, which is seen as the first step toward developing a consistent set of county-wide standards and procedures to protect Dane County Waters.
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.

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.
