Portsmouth Mine Pit Lake, sometimes called the Portsmouth Pit, is the deepest lake completely within the state of Minnesota, USA. It has a depth of over 450 feet (137 m), according to the most recent Minnesota DNR data. Lake Superior, over 700 feet deep off the north shore of the state, is technically deeper. The 120-acre (49 ha) artificial lake is a former iron mining pit in the Cuyuna Range that has since filled with water.
