Suggested Teaching Instructions
Map of Mohawk Valley from Schenectady to the Hudson River, Showing railroads, Barge Canal, old Erie Canal, Crescent and Vischer Ferry dams, and cities. Prepared by the State Department of Public Works, 1912.
The Erie, Champlain, Oswego, and Seneca-Cayuga Canals make up the divisions of the Barge Canal. The Champlain Canal runs from Waterford north to Fort Edward. The Erie Canal runs from the Hudson River through the Mohawk River to points west that include Rochester, Lockport and Buffalo. In order for the Barge Canal to operate successfully, it needs a constant and adequate supply of water. Vischers Dam and Crescent Dam were built to control the flow of the water along the canal and are examples of fixed dams. The dams keep the surface of the water at a fixed elevation above streams. Dams can also make the rivers into artificial lakes.
