Has a water moccasin ever been found in minnesota?

Water moccasins, also known as cottonmouths, are not native to Minnesota and are primarily found in the southeastern United States. There have been occasional reports of water moccasin sightings in Minnesota, but these are generally attributed to misidentifications or escaped pets. The state's climate and habitat are not suitable for their survival, making it highly unlikely to find a true population of water moccasins there.
