Its machinery was built in 1909 by the Bucyrus Co.","why_significant":"The dredge is tied to the construction and maintenance of the New York State Barge Canal between 1909 and 1957. It is described as a rare and very complete example of large steam-powered excavation equipment in the state. It is the last surviving steam-powered Barge Canal dredge to keep its steam plant and machinery, and is believed to be the last surviving machinery from the 1905-1918 canal construction.","narrative":"Dipper Dredge No. 3 is a steam-powered floating dredge, now sitting in the Lyons drydock of the New York State Barge Canal. Its riveted steel hull dates from 1929 and measures 110 feet long and 34 feet wide. Much of the machinery, including the steam engines, A-frame and boom, was built in 1909 by the Bucyrus Co. and first mounted on a wooden hull in 1910 for dredging the Mohawk River channel. New York State rebuilt the vessel in the late 1920s, and it worked on maintenance dredging until 1986, with a final run in 1988. It is considered significant for its role in building and maintaining the Barge Canal between 1909 and 1957. It is also the last surviving steam-powered canal dredge to retain its steam plant and machinery, and is believed to be the last machinery tied to the canal's original construction. It awaits restoration and public exhibition.","period_of_significance":"1909-1957","architect_builder":"Bucyrus Co.
