The dam in Ripon causes very heavy slime growth below the dam during warm periods of the year as well as eliminates fish migration resulting in several related problems like clam distribution and migration of trout. It also causes excessive warming. Silver Cr. has been classified Class II trout water from the Origin down to the impoundment.

The Silver Creek (From the top of the stream estuary near Green Lake to Willow Road southeast of Ripon) was assessed during the 2018 listing cycle; total phosphorus sample data clearly exceeded the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. Available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Temperature and chloride data clearly met thresholds. This water was not meeting this designated use and was considered impaired. Total phosphorus was being proposed as an added impairment.

The Silver Creek (Trout segment, Willow Road to headwaters) was assessed during the 2018 listing cycle; total phosphorus sample data clearly met the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. However, available biological data indicated impairment (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Temperature data did not exceed thresholds. This water was not meeting this designated use and was considered impaired.

The 2018 assessments of Silver Creek showed impairment by phosphorus; new total phosphorus sample data exceeded the 2018 WisCALM listing criteria for the Fish and Aquatic Life use. Available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Based on the most updated information, no change in the existing impaired waters listing was needed.

Silver Creek (146800) has been on the impaired waters list for Sediment/Total Suspended Solids since 1998 with elevated water temperature as an impairment. This water was assessed during the 2016 listing cycle; temperature data exceeded 2016 WisCALM listing thresholds for the Fish and Aquatic Life use.

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'.

Fish Management, Access
Replace perched culverts in the watershed to increase available fish and aquatic life habitat.
Best Management Practices, Implement
Implement cover crops to reduce cropland erosion during the late fall and spring.
Dam Safety or Removal
Mitigate impacts on water temperature and fish migration in Silver Creek from the Gothic Mill Dam in Ripon.
Management agencies and landowners in the watershed should work toward enhancing a combination of forest and native grass buffers, which may better reduce nutrients than strictly grassed buffers.
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.

Silver Creek is located in the Big Green Lake watershed which is 107.31 mi². Land use in the watershed is primarily agricultural (65%), open (15.50%) and a mix of wetland (10%) and other uses (14.00%). This watershed has 141.08 stream miles, 655.29 lake acres and 5,102.67 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Available 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.This water is ranked High Stream for individual InlandBeachs based on runoff problems and the likelihood of success from project implementation.
