Onsite Comments

No contaminants were found by ESD Field Office 1 or DNR Fisheries. The timing of thekill was consistent with a pollutant caused kill given the discovery of dead fish after a modest rainfall event thatfollowed an extended period of dry and warm weather. Only sucker species were found dead and that is notconsistent with a pollutant kill to find a single genus of fish. Our speculation is that this group of large-bodiedfish were located in a relatively small pool of water subjected to a contaminant and floated down to the locationthat they were found in a natural fish trap (a channel cut-off adjacent to the river).
