Fisheries spoke with two separate individuals that had been on or around the creek within the killed segment during the day on 8/17/19 and 8/18/19 and they did not observe any dead fish. This leads us to believe that the fish kill began sometime during or after the evening of 8/18/19, but before 8/21/19 when the kill was reported as fish were observed in various states of decay by 8/21/19. Also, fish were found on top of rocks in the middle of the stream and higher up on wetted sandbars suggesting that a high water event had occurred and when the flows subsided the dead fish were left where the water once was. Rains occurred the night of 8/19/19 and 8/20/19 and could have been enough to raise the creek for a short amount of time. This suggests that the kill occurred before at least one of the rain events.
