The Dewey Lake Monster is the name given to a legendary creature said to be approximately 10 feet (3.0 metres) tall and weighing about 500 pounds (230 kilograms), which first gained wide notoriety in June 1964 after several reported sightings near Dewey Lake in Dowagiac, Michigan. It is also referred to as the “Michigan Bigfoot” and “Sister Lakes Sasquatch”.
According to legend, the creature was rumored to dwell primarily along a stretch of swamp-land extending 15 miles (24 kilometres) from Dowagiac/Sister Lakes toward Decatur, Michigan (along Dewey Lake Street). In 1964, the tale gained national attention and caused a flood of curious thrill-seekers and monster-hunters to besiege the local community in the summer of 1964, some of whom offered photographs and plaster casts claimed to be of footprints of the creature.
Former Cass County Sheriff, Paul Parrish, was quoted as saying “it was one of the strangest times” in his “33 years of southwestern Michigan law enforcement.” He added: “We investigated it long and hard, but were never able to come up with whatever it was. But some good, honest, legitimate people” reported it.
