Erie Canal The Erie Canal is a canal in New York that is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal). Originally, it ran 363 mi from Albany, on the Hudson River, to Buffalo, at Lake Erie. It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. When completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly affected the development and economy of New York, New York City, and the United States.
St. Johns River The St. Johns River (Spanish: "Río San Juan" ) is the longest river in the U.S. state of Florida and its most significant one for commercial and recreational use. At 310 mi long, it winds through or borders twelve counties, three of which are the state's largest. The drop in elevation from headwaters to mouth is less than 30 ft ; like most Florida waterways, the St. Johns has a very low flow rate 0.3 mph and is often described as "lazy". Popular belief in the St. Johns area holds that it is one of the few rivers that flow north, although north-flowing rivers are common. Numerous lakes are formed by the river or flow into it, but as a river its widest point is nearly 3 mi across. The narrowest point is in the headwaters, an unnavigable marsh in Indian River County. The St. Johns drainage basin of 8840 sqmi includes some of Florida's major wetlands. It is separated into three major basins and two associated watersheds for Lake George and the Ocklawaha River, all managed by the St. Johns River Water Management District.
