Cumberland and Oxford Canal
The 18-mile long Presumpscot River portion of the canal fell into disuse when the Portland and Ogdensburg Railroad (later Maine Central Railroad) reached Sebago Lake Station in 1870. Some of the Presumpscot River lock facilities were converted to hydroelectric dams. Steamboats continued to use Songo Lock to provide transportation from Sebago Lake Station to the lakeside communities of Bridgton, Harrison, Naples, Sebago, Casco, Raymond and North Windham. The Bridgton and Saco River Railroad reached Bridgton in 1883 and Harrison in 1898. The Sebago Lake, Songo River, and Bay of Naples Steamboat Company continued to offer summer passenger service to tourists until the last steamboat Goodrich burned at its Naples dock in 1932. Songo Lock remains in service for pleasure boats.
