Aurora, Illinois' serious fish kill in the summer of 1953.

Dear Tom,
During a summer in the early 1950s, I recall Aurora trucks picking up dead fish from the banks of the Fox River. Was hot, dry weather the cause?

Dear Mel,
According to records from the Aurora Sanitary District sewage treatment plants, a combination of low water flow in the Fox River and high temperatures resulted in a serious fish kill in the summer of 1953. The water temperature rose to high as 108 degrees, literally cooking the fish. In Chicago, that summer featured 42 days of 90 degrees or higher temperatures, including four days where the mercury topped 100, while rainfall was nearly two inches below normal. The following summer was also hot with 36 days of 90 degrees or higher, but rainfall was substantially higher, averaging about three inches above normal. Any low-water problems disappeared in October 1954 when a record 12.06 inches of rain soaked the Chicago area.
