Fish and Aquatic Life
The Stony Creek Su atershed, located in the southeastern portion of the watershed, consists of Stony Creek, two
other unnamed perennial streams, two intermittent streams and Haack Lake.
Water Resources. Stony Creek originates in wetlands and also as an intermittent outlet from Haack
discharges to the North Branch of the Milwaukee River at T12N-R20-Sec3 SWSW. The stream is channelized
downstream of Forest Road and is impounded at Boltonville, approximately 4.1 miles downstream of the headwaters.
Stony Creek is joined by two perennial and two small intermittent tributaries. From the headlands to approximately
&st Moraine Drive, the stream is bordered by lowland, swamp hardwoods. In-stream habitat limitations such as
siltation in slackwater, pools and runs, suggest that sediment transport from nonpoint sources and stream bank erosion
is significant in wet weather. Bacteriological contamination appears to be a problem downstream of STH 144.
Analysis of the bacterial fecal co1iform:streptococcus ratios suggest mixed human/animal waste loading.
Haack Lake is the only natural lake in this subwatershed. It is predominantly a seepage lake with a surface area of 12
acres and a maximum depth of 22 feet. Depending on the precipitation in a given year, Haack Lake flows to an
intermittent outlet in the headwater wetlands of Stony Creek. Haack Lake is surrounded by wooded wetlands, similar
to the wetlands in the headwaters region of the creek.
The Boltonville millpond was created by a low-head dam on Stony Creek. It has a surface area of 11 acres and
maximum depth of approximately 10 feet. As to be expected of an impoundment, heavy siltation, turbidity and weed
infestation are major problems in this impoundment. Discharge from the impoundment also results in significant
warming of downstream water temperatures. Boltonville Millpond was dredged in 1985 and is currently maintained by
the Boltonville Sportsmans' Club.
Stony Creek has a full-body recreational classification but may be unhealthy during periods of wet weather due to
bacterial contamination. There is no public access to Boltonville Millpond.

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.
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.

Stony Creek is located in the North Branch Milwaukee River watershed which is 149.67 mi². Land use in the watershed is primarily agricultural (45.40%), grassland (20.30%) and a mix of wetland (15.50%) and other uses (18.80%). This watershed has 159.81 stream miles, 886.38 lake acres and 13,793.69 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.
