In the spring of 1950 the Red and Assiniboine Rivers overflowed their banks and threatened Winnipeg. Thousands of citizens had to be evacuated from their homes and sent to neighbouring towns and provinces. "Chippawa" became the centre of flood-fighting activities and naval personnel, both Regular and Reserve, were sent to Winnipeg from all over the country and lived on board "Chippawa" for several weeks. The ship's galley was activated and within 48 hours was serving 1,500 meals a day to the flood fighters. "Chippawa"s Main Drill Deck served as a marshalling area for motor boats and other marine craft used during the flood.
