Fish and Aquatic Life
Penn Hollow Creek is a tributary to Otter Creek. The creek is classified as a Class II trout stream. Overall, the creekÃ½s flow is limited. There is limited information available on this stream.

Penn Hollow Creek - Mouth location T8N R5E Section 35 -1, Surface area = 2.3 acres, Length = 4.0 miles, Gradient = 45 feet per mile, Total alkalinity = 234.0 mg/l, Volume of flow = 0.9 cfs.
Penn Hollow is a small springg and seepage fed tributary of Otter Creek. About 60 percent of its watershed is cleared for farming and heavy stream bank erosion is evident in its lower sections. It has a small tributary which enters about midway in its length. There is a potential source of pollution in a cheese factory located just above this tributary with a history of stream contamination. This is no sport fishery on this stream and only a small forage fish population exists. Forage fish species present include redbelly dace, creek chub, and brook sticklebacks.

Penn Hollow Creek (WBIC 1237300) 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.

Penn Hollow Creek is located in the Otter and Morrey Creeks watershed which is 198.69 mi². Land use in the watershed is primarily forest (48%), agricultural (42%) and a mix of wetland (4%) and other uses (6%). This watershed has 437.57 stream miles, 351.55 lake acres and 5,785.74 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Low 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.
