Highlighted river segments indicate those impacted in part or whole by this fish kill event. It is not meant to represent the actual extent of the kill.
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).
