Fish and Aquatic Life
The Gribble Branch is a spring fed, cold water stream that is a tributary to the Dodge Branch. The stream is stocked with brown trout and currently supports a Class II trout fishery. Nonpoint source pollution and stream bank pasturing cause problems for habitat in the river and probably keep the Gribble Branch from reaching its potential as a Class I trout stream. The stream has not been monitored in recent years.

Gribble Creek - Mouth location T5N R4E Section 20 -5, Surface area = 1.2 acres, Length = 2.5 miles, Gradient = 72.0 feet per mile, Total alkalinity 274 mg/l, Volume of flow = 1.0 cfs.
Gribble Creek is a spring fed tributary of the Dodge Branch and flows northeasterly. Its gradient is very high and bank erosion is severe as a result of recurring floods which are a serious problem. About 78 percent of its watershed area is farmed which further accentuates the heavy runoff problem. Siltation and turbidity, as a result of erosion, are believed to be detrimental to the sport fishery which consists of brown trout stocked on an annual basis. Forage fish species which inhabit this stream include white suckers, bluntnose and stoneroller minnows, redbelly dace, creek chub, common shiners, fantail and johnny darters, and brook sticklebacks. Game assets are limited to some muskrats near the mouth. There are no
public lands on this stream but it is accessible from two town road crossings

Gribble Branch was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water is meeting this designated use and is not considered impaired.

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 2016 . See also 'monitoring' and 'projects'.
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 and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.
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.

Gribble Branch is located in the Upper East Branch Pecatonica River watershed which is 140.18 mi². Land use in the watershed is primarily agricultural (72%), forest (18%) and a mix of suburban (7%) and other uses (4%). This watershed has 395.65 stream miles, 61.72 lake acres and 834.33 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked 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.
