Do both The Portage Canal and Erie Canal allow connection to the Atlantic Ocean ?
Portage Canal The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway. For a time, it completed a route from the north Atlantic Ocean, through the St. Lawrence Seaway and down the Mississippi River to the Gulf of Mexico, and back to the Atlantic.
Chemung Canal The Chemung Canal is a former canal in New York, United States. The canal connected Seneca Lake at Watkins Glen to the Chemung River at Elmira, New York. It was planned to connect the Finger Lakes region and Pennsylvania's Susquehanna River watershed with New York's Erie Canal system. The latter connected the Great Lakes with the Hudson River and ultimately the Atlantic port of New York City.
