State officials have upped their estimate of the number of fish killed by that ammonia spill December 14th in Kossuth County. Biologists now say nearly one-point-three million fish were killed along a 31 mile stretch of Lotts Creek and another 17 miles of the East Fork of the Des Moines River. The value of the fish killed: nearly 150-thousand dollars. It’s the largest fish kill since records have been kept in Iowa. The ammonia was spilled when a pipeline near Whittemore ruptured.
