Fish and Aquatic Life
Olson Creek is a small spring fed creek that originates southwest of Hollandale and flows southeasterly into the East Branch of the Pecatonica River. It is a Class II trout fishery for 4 of its 5 miles. Brown trout continue to be stocked into the stream. A 1999 stocking of brook trout has not been evaluated. This stream has not been monitored recently.

Olson Creek - Mouth location T4N R5E Section 9 -2, Surface area = 3.1 acres, Length = 4.0 miles, Gradient = 45.0 feet per mile, Total alkalinity = 275.0 mg/l, Volume of flow = 2.4 cfs.
Olson Creek is a small spring fed stream which flows southeasterly into the East Branch of the Pecatonica River. About 85 percent of its watershed area is cleared for farming and flooding with subsequent bank erosion is commonplace, especially in the lower sections. The sport fishery consists of brown trout which are maintained by stocking. Forage fish species include hornyhead and creek chubs, common shiner, redbelly dace, stoneroller minnows, sculpins and brook sticklebacks. Furbearers such as muskrats are common throughout most of its length. There are no public lands. At the present time it can be reached from a county road. bridge.

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.

Olson Creek is located in the Upper East Branch Pecatonica River watershed which is 140.18 mi². Land use in the watershed is primarily grassland (52.10%), agricultural (22.10%) and a mix of forest (20.70%) and other uses (5.10%). This watershed has 395.65 stream miles, 61.72 lake acres and 834.33 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked 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.
