Fish and Aquatic Life
Smokey Hollow Creek is a spring fed tributary to Pompey Pillar Creek. It is a Class II trout stream with limited flow. The creek has problems with bank erosion. A sediment detention dam was constructed on the stream to help reduce soil erosion and sedimentation in the creek.

Smoky Hollow Creek - Mouth location T7N R2E Section 17 -3, Surface area = 3.8 acres, Length = 3.5 miles, Gradient = 45.8 feet per mile, Total alkalinity = 236.0 mg/l, Volume of flow = 1.5 cfs.
Smokey Hollow Creek is a spring fed tributary of Pompey Pillar Creek and is considered a good trout stream. Its gradient is average for the county and 75 percent of the watershed is cleared for agricultural purposes. As a result, precipitation runs off rapidly and heavy bank erosion is common; especially in the lower sections. Within the last few years an erosion control plan was proposed by local and government groups for the Otter Creek watershed. In this plan, a multi-purpose structure was planned for Smoky Hollow Creek. Local and state interest in saving the trout stream prevented the construction of a permanent pool, however, the problem of flooding and soil erosion will be reduced by the construction of detention dam above Highway P. The present sport fishery consists of brown trout which are stocked annually by the Department of Natural Resources and local sportsmen. There is also a large forage fish population which includes white and hogsuckers; redbelly, blacknose and longnose dace; creek and horny- head chubs; bigmouth and common shiners and johnny darters. Green sunfish are also known to inhabit these waters.
Aquatic game assets are restricted to some muskrats where good bank cover exists. There are no public lands or easements along the stream to assure public access. Presently it is accessible from only one road crossing.

Smokey Hollow Creek (1238000), from the mouth to the 4th trib., was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) sample data were clearly below the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water was meeting this designated use and was 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'.
Monitor Water Quality or Sediment
Appears weather extremely warm for 30 days prior to sample date...Perhaps monitor this station again before recommending a change in NC.

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.

Smoky 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.
