Onsite Comments
No contaminants were found by ESD Field Office 1 or DNR Fisheries. The timing of the kill was consistent with a pollutant caused kill given the discovery of dead fish after a modest rainfall event that followed an extended period of dry and warm weather. Only sucker species were found dead and that is not consistent with a pollutant kill to find a single genus of fish. Our speculation is that this group of large-bodied fish were located in a relatively small pool of water subjected to a contaminant and floated down to the location that they were found in a natural fish trap (a channel cut-off adjacent to the river).
