All locks on the New York State Canal System are single-chamber; the dimensions are 328 feet (100 m) long and 45 feet (14 m) wide with a minimum 12-foot (3.7 m) depth of water over the miter sills at the upstream gates upon lift. They can accommodate a vessel up to 300 feet (91 m) long and 43.5 feet (13.3 m) wide.
Fitch successfully trialled his boat in 1787, and in 1788, he began operating a regular commercial service along the Delaware River between Philadelphia and Burlington, New Jersey, carrying as many as 30 passengers. This boat could typically make 7 to 8 miles per hour (11 to 13 km/h) and travelled more than 2,000 miles (3,200 km) during its ...
The Mandan villages in what is now North Dakota were reached on October 26, after 1,500 miles (2,400 km) of travel from Camp Dubois. The expedition built and wintered at Fort Mandan . The keelboat was sent back to St. Louis with the returning party on April 6, 1805, while the remainder of the expedition continued overland to the Pacific Ocean.

Between 1958 and 1967, an average of 7.1 people per year went over the falls. From 1978 to 1988, the average was 12.8 per year. [10] Other reports suggest an annual average between 20 and 30. [11] By 1900, approximately 1,000 people were believed to have gone over the falls in acts of suicide. [12]
The smaller boat, which is travelling downstream, is moving very fast, driven by the large water sails on either side and is thereby hauling the larger boat upstream against the current. [4] The large barge in the picture has two, side-mounted water wheels that coil up the cable and increase its speed further.
The Union fought her way upstream for 90 miles (140 km) and could not ascend any further. The telegraph company then decided to build their own sternwheeler, the Mumford, and she left Victoria under Captain Coffin in July 1866. This time Coffin travelled 110 miles (180 km) upstream, a feat he repeated three times, successfully delivering 150 ...
