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.
Newichawannock Canal The Newichawannock Canal is a man-made canal which drains Great East Lake into Horn Pond at the border between Wakefield, New Hampshire, and Acton, Maine, in the northeastern United States. It is at the head of the Salmon Falls River, which the Abenaki called "Newichawannock", meaning "river with many falls". Begun in 1850 by the Great Falls Company to increase the water available for its mills in Somersworth, New Hampshire, the 0.75 mi canal is unusual as it was built for strictly industrial purposes in an area remote from the actual industrial site. The canal forms the boundary between the states of New Hampshire and Maine, and is spanned by a stone bridge built at the same time. The canal and bridge, along with related artifacts, were listed on the National Register of Historic Places in 2014.
