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.
The source originated from manure runoff from a dairy cattle facility that flowed down the highway ditch and entered the unnamed creek in section 13 (UTM X = 625168.22, Y = 4669309.85). The kill traveled was approximately 1.5 stream miles until the creek dried up before it entered the Wapsipinicon River. The end of the kill was still in Sec 13 at (UTM X = 625107.43, Y = 4670713.71). When we got approximately half way through the kill the entire creek was completely frozen over. If you would break through the ice you could see the manure still flowing under the ice and dead fish were seen. We were able to count 613 dead fish in the upper open water section and took that number times two to account for the number of dead fish that we were unable to see under the ice in the lower section. The water was extremely turbid and this number is probably a small percentage of the fish that were actually killed.
