Impaired Water Notes
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; 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 stream segment was reassessed during the 2012 assessment cycle using data from 2001-2010 and revised assessment methodology (draft 2014 WisCALM). Using this methodology, total phosphorus data exceed criteria for the Fish and Aquatic Life use; however, available biological data do not indicate impairment.
