Onsite Comments
Hundreds of dead fish were found along approximately a mile-and-a-half long stretch of a tributary of Ralston Creek which runs through the park and a residential area, The fish kill was reported Sunday afternoon by a citizen. The creek was traced back to a tile line in a rural area, but there was no indication of manure or fertilizer run-off based on field testing. Analysis of water samples were inconclusive and no cause determination can be made at this time.
