Walk-in-the-Water was a sidewheel steamboat that played a pioneering role in steamboat navigation on the Great Lakes. She was the first such craft to run on Lake Erie, Lake Huron and Lake Michigan. Launched in 1818, she transported people and supplies to sites and points of interest around the Great Lakes, before being grounded and wrecked in a gale force storm in Buffalo's bay in 1821. According to some sources, Walk-in-the-Water's name originated from an Indian's impression of a steamboat moving ("walking") on the water with no sails.
