Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was listed in 2006 303d list for TSS and a TSS TMDL was approved 2005; also on 2002 Trout streams list (class 2).
This water was assessed during the 2012 listing cycle, and total phosphorus sample data exceed 2012 WisCALM listing criteria for the fish and aquatic life use, and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category). This water was assessed during the 2014 listing cycle; total phosphorus sample data exceed 2014 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category).
This water was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use, however, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category).
This water was assessed during the 2018 listing cycle; new total phosphorus sample data exceed 2018 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category).

Impaired Water Notes
Based on the total phosphorus criteria excursions and the corroborating biological assessment, “degraded biological community” impairment was added to the existing impaired water listing in 2012.

Impaired Water Notes
Silver Spring Creek is located in southeastern Lafayette County and is part of the Lower Pecatonica River watershed. Originating south of the town of Lamont, the stream flows five miles south and empties into the Pecatonica River north of Gratiot. All five miles of Silver Spring Creek are currently listed on the 303(d) list due to degraded habitat resulting from sedimentation from non-point source pollution. A 2001 fish survey from the Silver Spring Creek Rd. crossing found seven brown trout (3.0 - 14.5 inches) and eight other minnow and forage species, including the presence of brook stickleback, a cool-water indicator. Silver Spring Creek’s current use is as a warm water forage fishery, but the lower 3.9 miles are classified as a Class II trout fishery.
