In 1917, the Grant Lumber Company caught fire and the ensuing blaze consumed about half of the residential area of Harrison and about half of the business district. Much of the town was never rebuilt. The easiest way to get to Harrison was by water. The OWR&N Company which absorbed the OR&N railroad, constructed a 600-passenger steamer called “The Harrison” for transportation. There were several other steamers such as the Georgie Oakes that carried passengers and freight making the depot a popular place for area children. Passenger service was discontinued in the early 1920s but they continued to haul freight until 1932 when the line was abandoned.
