Description:The young carp shown swimming in this historic 1936 photograph, were displaying signs of oxygen hunger by “gulping” air through the lake surface interface. The picture was taken at Lake Merion, near Brownton, Minnesota on February 3 of that year, and offered as evidence that pollution of the water had occurred, which caused the oxygen level in the water to dramatically decline.
This is one of a series of instructional images used by the Minnesota Board of Health to train its public health workers. The focus of the images and the training, was on protecting water supplies from bacterial contamination due to incorrect disposal of waste, such as sewage, that might foul ground water, rivers, lakes, and streams.
