bod & phosphorus. Sediment added as impairment/pollutant to 2006 303d list changes. Assessed in 2012, and TP 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 overwhelmingly 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; temperature data exceeded 2016 WisCALM listing thresholds for the Fish and Aquatic Life use. Total phosphorus sample data overwhelmingly exceed 2016 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 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 fish Index of Biotic Integrity (IBI) scored in the poor condition category).

Impaired Water Notes
Dougherty Creek is a sixteen-mile long stream that currently exists as a Class II trout stream for much of its length. Only the upper two miles are on the state’s list of impaired waters because of degraded habitat due to sedimentation, phosphorous, and BOD from non-point source pollution. Because of its length, the stream flows through a variety of land uses including small patches of forest, cropland, and wetland, but also through pasture where it suffers severe bank erosion. The stream bottom above Apple Grove Road is primarily gravel. Below this area, silt becomes more prevalent and the water more turbid. While most of the stream is managed for brown trout, some rainbow trout have been stocked and show up in stream surveys. Tolerant, warm water forage species are common in the stream including white sucker, common shiner, and creek chub. Mottled sculpin and other intolerant species are found in low numbers. As part of a structured habitat survey in 2002, Department staff found that the stream has extensive (79% silt and clay) fines covering the substrate. According to the Department’s habitat rating guidelines, this is considered poor habitat. Past resource objectives were to improve the trout fishery, reduce organic loading and erosion, to increase aquatic diversity, and to improve wildlife habitat. There have been some improvements to the stream habitat, and certain areas of the riparian corridor have been returned to prairie. Land use in the upper 2 miles of stream has improved. Monitoring of this section should be conducted to determine contemporary conditions.

Dougherty Creek is a moderate sized stream that has an existing use as a Class II trout stream for much of its length. The upper 2 miles has an existing use as a limited forage fishery and is on the state’s list of impaired waters for habitat degradation and dissolved oxygen problems. While most of this short section of stream has now been put in a set-aside program, there are several barnyards at the headwaters of the stream that were identified as sources of nutrients and biochemical oxygen demand (BOD) to the stream (Marshall, 1991; WDNR, 2008). The stream flows through small patches of forest, cropland, and wetland, but also through pasture where it suffers severe bank erosion. The stream bottom above Apple Grove Road is primarily gravel. Below this area, silt and clay become more prevalent and the water is more turbid (Marshall, 1991).

While most of the stream is managed for brown trout, some rainbow trout have been stocked and show up in stream surveys. Tolerant, eurythermal forage fish species are common in the stream including white sucker and creek chub. Mottled sculpin, and intolerant species, are found in low to moderate numbers.

Goals of the priority watershed project were to improve the trout fishery, reduce organic loading and erosion, increase aquatic diversity and improve wildlife habitat. There has been some habitat improvement work done on the stream, primarily upstream from Prairie View Road. These have resulted in localized improvements in trout numbers with 2007 coldwater IBI ratings of “fair” to “good”. Small sections have been fenced and certain areas of the riparian corridor have been returned to prairie - especially in the upper ½ of the stream. The lower ½ of the stream runs through row crops and grazed wet meadows. Biologists noted that the U-shaped channel offers little in the way of habitat save for depth and overhanging grasses and banks. This bigger water could offer an opportunity to attract higher numbers of larger fish if habitat could be improved.
