Dry Hollow Creek is a small spring-fed tributary to the Big Green River. About 0.6 miles of
its length are Class I trout. A number of barnyards adjacent to the creek are thought to be
affecting stream habitat and water quality. The stream experiences problems with streambank
pasturing and erosion.

Dry Hollow Creek is a small spring-fed tributary to the Big Green River. About 0.6 miles of its length is listed as Class II trout waters. It has been recommended that this segment be upgraded to Class I trout waters and listed as an exceptional resource water (ERW). A number of barnyards adjacent to the creek are thought to be affecting stream habitat and water quality. The stream experiences problems with streambank pasturing and erosion.

A very short, spring-fed tributary of Big Green River located two miles northwest of Werley. Heavy bank erosion is common within the watershed. The stream is small with very clear water. Gravel is the principal bottom type. Forage fish dominate the fishery but a few native brown trout fingerling can be found. Larger browns can be seen spawning in this small tributary during late autumn. Game assets include raccoon, squirrels, red and gray fox, white-tailed deer, and ruffed grouse. Access is possible with permission from a road paralleling the stream. One farm dwelling is adjacent to the stream.

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.

Dry Hollow Creek is located in the Green River and Crooked Creek watershed which is 125.71 mi². Land use in the watershed is primarily forest (45%), agricultural (41%) and a mix of suburban (6%) and other uses (8%). This watershed has 278.95 stream miles, 257.04 lake acres and 4,127.32 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.
