Impaired Water - Pioneer Valley Creek (Pioneer Valley Creek)
Green County, Wisconsin
SP14
883100
0.00 - 4.16
4.16
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
TMDL approved 2005.
This five-mile stream runs through a highly pastured watershed, which results in a fairly poor quality stream with
scarce bank cover and heavy erosion. Only small numbers of forage species are present in the stream. It is on the
state's list of impaired (303d) waters due to sediment as the non-point source pollutant and degraded habitat as the
impairment. Currently, this is a limited forage fishery but is listed to potentially be a warm water forage fishery. There
are no HBI and IBI scores available, as this stream has not been monitored in recent years.
This water was assessed during the 2014 listing cycle; phosphorus sample data nearly exceeded (May Exceed) 2014 WisCALM listing thresholds for the Fish and Aquatic Life use, and no biological sample data, macroinvertebrate or fish Index of Biotic Integrity (IBI), were available. Further monitoring is recommended.

This water was assessed during the 2018 listing cycle; new total phosphorus sample data may exceed 2018 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).

Assessments during the 2020 listing cycle showed new bug and fish sample data were in good condition.
