Onsite Comments
Dead fish were concentrated in small backwater oxbow. Probable that with heavy rains in the area on 9/13/03 the carp moved into backwaters and oxbow. When stream level dropped the fish were trapped in the oxbow with no oxygen or water. Reporter noticed a muddy smell on 9/14 and fish flopping and trapped. During investigation oxygen levels were at >15ppm and ammonia 1-1.5. The water was clear to mud stained.
