Impaired Water - Black River (Black River)
La Crosse, Trempealeau County, Wisconsin
BR01, BR03
1676700
14.52 - 37.01
22.49
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This segment of the Black River (from Lake Arbutus to Black River Falls) was
delisted for Mercury in 2008, but remained listed for PCBs.

This water was assessed during the 2012 listing cycle, and new fish tissue mercury concentration data indicate that a specific advisory is warranted and the impairment for mercury was added. This stream segment was assessed during the 2012 listing cycle, and total phosphorus sample data exceed criteria for the fish and aquatic life use.

This water was assessed during the 2014 listing cycle; total phosphorus sample data overwhelmingly exceed 2014 WisCALM listing thresholds for the Fish and Aquatic Life use, however, no biological data (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) were available to assess biological impairment).

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. This water was assessed for chlorides and sample data did not exceed 2016 WisCALM chronic and acute listing criteria for the Fish and Aquatic Life use. This water was also assessed for temperature and sample data did not exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use.

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. New biological (macroinvertebrate and fish Index of Biotic Integrity (IBI) scores), chloride, and temperature sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use.

Assessments of new total phosphorus data during the 2020 listing cycle showed conditions too high for healthy aquatic communities like plants, fish, and bugs. Chloride data were also assessed and did not indicate impairment.

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, 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).

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data exceeded 2020 WisCALM listing criteria for the 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). Based on the most updated information, no change in existing impaired waters listing is needed.

New Fish Data. TMDL 51 should be Black River from Lake Arbutus to Black River Falls, not L. Arbutus to Miss. River. Listed for Hg for FCA. TMDL ID = 707 and 51 (remove this portion 2008), ie., lower segments. This AU: Mouth (at Long Lake, Miss. R.) to the La Crosse-Trempealeau-Jackson county line. 303(d) portion runs from 0-48.5.
