Personal Flotation Devices (PFDs): A Canadian approved PFD is designed to keep you afloat in the water. PFDs were designed for use in recreational boating and are generally smaller, less bulky and more comfortable than lifejackets.
The Erie Canal, in New York state (shown below), was 360 mi (580 km) long, and connected New York with the Great Lakes via the Hudson River. Locks were built to overcome the 571-ft (174-m) difference between the level of the river and that of Lake Erie.
The Erie Canal would connect to the port of New York City by beginning at the Hudson river near Troy, New York. The Hudson River flows into New York Bay and past the west side of Manhattan in New York City. From Troy, the canal would flow to Rome (New York) and then through Syracuse and Rochester to Buffalo, located on the northeast coast of Lake Erie.
