Yesterday, I received word that there had been a fish kill on the Rush River. Eye witnesses found dead trout, rough fish, minnows, sculpins and other aquatic life up river of the bridge at Centerville in St, Croix County and for at least 3/4 of a mile down stream of Centerville. The location and cause of the kill is still under investigation. I placed a call to Marty Engel, DNR Senior Fisheries Biologist for the area. The message on his phone was that DNR was aware of the kill on the Rush River. The recording asked for name and number and communicated that the call would be returned. I left that information and I am awaiting a return call.
