Fish and Aquatic Life
Poplar Creek, located in northwestern Vernon County and southeastern La Crosse County, flows for approximately two miles in a southerly direction before reaching Coon Creek northeast of Coon Valley. In Vernon County, this stream is also known as Creek 4-8. In La Crosse County, this stream is also known as Creek 33-1. This stream has a steep gradient of 100 feet per mile and drains steep forested land and agricultural lowland pasture. Poplar Creek is a Class I trout stream for its entire length. The La Crosse County portion of this stream is designated as an Exceptional Resource Water.

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 2018. See also the 'monitoring and projects' tab.
Monitor Fish Community
WDNR should conduct a fish and habitat survey of Poplar Creek to document existing conditions.
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.

Unnamed is located in the Coon Creek watershed which is 238.20 mi². Land use in the watershed is primarily forest (44.60%), grassland (21.30%) and a mix of agricultural (16.50%) and other uses (17.60%). This watershed has 574.90 stream miles, 4,342.05 lake acres and 6,052.31 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Ranked for runoff impacts on lakes and Medium for runoff impacts on groundwater and therefore has an overall rank of Medium. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.This water is ranked Medium Stream for individual Rivers based on runoff problems and the likelihood of success from project implementation.
