This historic photograph was taken on August 30, 1935, for the purpose of documenting a fish kill. A large number of fish were killed when industrial waste contaminated the Blue Earth River, near Winnebago, Minnesota. The waste had originated from a canning plant located on the river, which depleted the water's oxygen supply, creating an uninhabitable environment for the river's natural inhabitants.
