Impaired Water - Spring Creek (Spring Creek)
Green County, Wisconsin
SP11
877000
0.00 - 10.31
10.31
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
On 2006 303d list, TMDL has been approved 2005.
Spring Creek is located in southeastern Green County and is part of the Lower Sugar River watershed. Originating
south of Juda, it flows to the east for ten miles before it drains into the Sugar River, south of Brodhead. Spring Creek
flows mainly through agricultural land, and much of the stream length had been ditched for cropland drainage. The
lower ten miles of the stream are currently listed on the 303(d) list for degraded habitat due to sedimentation from nonpoint
sources. A habitat evaluation was conducted above the CTH G bridge crossing in 2002 and found that about 48%
of the substrate in the surveyed section was composed of fine sediment, which is considered to be ?fair? habitat based
on the Department?s habitat rating guidelines. Width to depth ratios averaged 16:1 for this segment of the stream,
which is also considered to be ?fair? habitat quality.

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 of new total phosphorus data during the 2020 listing cycle showed conditions unclear for healthy aquatic communities like plants, fish, and bugs.

Impaired Water Notes
Spring Creek is located in southeastern Green County and is part of the Lower Sugar River watershed. Originating south of Juda, it flows to the east for ten miles before it drains into the Sugar River, south of Brodhead. Spring Creek flows mainly through agricultural land, and much of the stream length had been ditched for cropland drainage. The lower ten miles of the stream are currently listed on the 303(d) list for degraded habitat due to sedimentation from nonpoint sources. A habitat evaluation was conducted above the CTH G bridge crossing in 2002 and found that about 48% of the substrate in the surveyed section was composed of fine sediment, which is considered to be “fair” habitat based on the Department’s habitat rating guidelines. Width to depth ratios averaged 16:1 for this segment of the stream, which is also considered to be “fair” habitat quality. A 2002 fish survey, about three miles upstream of where Spring Creek meets the Sugar River, found one brown trout (25.5 inches) two northern pike (15.5, 21.5 inches) and 16 other minnow and forage species, of which, white sucker and common shiner were most abundant. Two brassy minnows, which are cool-water indicators, were also seen during this survey. The HBI score, based on a macroinvertebrate sample taken in 2002, was 5.422, which suggests “good” water quality with some organic pollution. Currently, Spring Creek is listed as a warm water forage fishery; however, it has the potential to become a warm water sport fishery. Buffer strips and bank stabilization would enhance this stream.
