Fish and Aquatic Life
Nederlo Creek, also known as Johnstown Creek, is located in north central Crawford County.
This stream flows in a north easterly direction for 4.1 miles before reaching Tainter Creek
north of Gays Mills. Nederlo Creek has a gradient of 27 feet per mile and drains forested
hillsides and agricultural valleys. Nederlo Creek is a Class II trout stream upstream of
Freeman Road for 2.1 miles and Class III downstream of Freeman Road for 2.0 miles.
The most recent survey, conducted in 1998, documented a small brown trout population and a
very diverse community of forage fish species. At the time, sand and silt made up nearly 50%
of the stream bottom followed by cobble (41%) and small amounts of gravel and boulder. The
majority of in-stream cover consisted of aquatic vegetation and some boulders. Habitat seems
to be the limiting factor for trout in Nederlo Creek. Streambank pasturing of livestock contributes
greatly to the sediment problems of the stream. Nederlo Creek would benefit from
the purchase of streambank easements from willing sellers and the restoration of in-stream
habitat. WDNR records indicate that Nederlo Creek was stocked with brown trout yearly from
1959 to 1995. Brook trout have been stocked since 1999. Access to Nederlo Creek is from
one road crossing and a WDNR easement.

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 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.

Nederlo Creek is located in the Reads and Tainter Creeks watershed which is 135.69 mi². Land use in the watershed is primarily forest (47.20%), agricultural (24%) and a mix of grassland (23.30%) and other uses (5.50%). This watershed has 339.00 stream miles, 221.66 lake acres and 1,867.13 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High 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.
