Question: which is located further east, The Susquehanna and Tidewater Canal or the Portage Canal?
Context: The Fox–Wisconsin Waterway is a waterway formed by the Fox and Wisconsin Rivers. First used by European settlers in 1673 during the expedition of Marquette & Joliet, it was one of the principal routes used by travelers between the Great Lakes and the Mississippi River until the completion of the Illinois and Michigan Canal in 1848 and the arrival of railroads.  The western terminus of the Fox–Wisconsin Waterway was at the Mississippi at Prairie du Chien, Wisconsin.  It continued up the Wisconsin River about 116 miles (187 km) until reaching Portage, Wisconsin.  There travelers would portage to the Upper Fox River, or eventually, use the Portage Canal.  It continued about 160 miles (257 km) down the Fox River, following it through Lake Winnebago and continuing on the Lower Fox over 170 feet (50 m) of falls to the eastern terminus of Green Bay. State Route 116 (SR 116) is a 9.83 mi state highway in the U.S. state of Washington, serving Indian and Marrowstone islands in Jefferson County.  The two-lane highway travels east from SR 19 in Port Hadlock-Irondale across the Portage Canal to Indian Island and Marrowstone Island, turning north and ending at the entrance to Fort Flagler State Park.  SR 116 was created in 1991 and follows the route of Flagler Road, built and paved in the 1960s. Southern Terminal, Susquehanna and Tidewater Canal The Susquehanna Canal of the Pennsylvania Canal System was funded and authorized as part of the 1826 Main Line of Public Works enabling act, and would later become the Susquehanna Division of the Pennsylvania Canal under the Pennsylvania Canal Commission.  Constructed early on in America's brief canal age, it formed an integral segment of the water focused transportation system which cut Philadelphia-Pittsburgh (pre-railroad) travel time from nearly a month to just four days.  One of the system's navigations, the Susquehanna Canal/division created a mule-towed navigable channel 41 mi along the west bank of the main stem of the Susquehanna River between a lock terminus near the mouth of the Juniata Tributary River and the canal basin at Northumberland.  Meeting the West Branch Canal and the North Branch Canal at Northumberland, it formed a link between the public and private canals upriver and the main east–west Pennsylvania Canal route known as the Main Line of Public Works which was devised to connect Philadelphia to Pittsburgh, southern New York, northern Pennsylvania and Lake Erie using most of the far reaches of the Susquehanna's tributaries. Pennsylvania Canal "(or sometimes Pennsylvania Canal system)" refers generally to a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts.  The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items.  It should be understood the "first use of any railway" in North America was the year 1826, so the newspapers and the Pennsylvania Assembly of 1824 applied the term then to the proposed Right of ways mainly for the canals of the Main Line of Public Works to be built across the southern part of Pennsylvania.  Enacted before Railroads gestated during their infancy, the focus of the act was to create through building a canal system, the capability to ship heavy or bulk goods and connect Philadelphia to Pittsburgh—and "more importantly"—and "beyond" to the "new growth markets" in the developing territories reached by the Ohio River now called the midwest.  Later, when updated in 1837 to reflect the experience of twelve years of toddler-railways, the term was also applied to railroads and new canals to be added to the state transportation system.  As a crowning achievement, the Main Line of Public Works and the Pennsylvania Canal system topped 2100 ft in elevation by erecting the Allegheny Portage Railroad, which used a system of five inclines and five planes on each side of the Eastern Continental Divide at Cresson Pass in Cambria County to actually haul wheeled flat cars, which had halved canal boats placed on them, up and over the Allegheny Front and connect Pittsburgh to the Susquehanna.  When finished in 1834 the trip from Philadelphia to Pittsburgh could be made in 3–5 days, weather conditions depending. The Keweenaw Waterway is a partly natural, partly artificial waterway which cuts across the Keweenaw Peninsula of Michigan; it separates Copper Island from the mainland.  Parts of the waterway are variously known as the Keweenaw Waterway, Portage Canal, Portage Lake Canal, Portage River, Lily Pond, Torch Lake, and Portage Lake.  The waterway connects to Lake Superior at its north and south entries (upper and lower portage entry lighthouses), with sections known as Portage Lake and Torch Lake in between.  The primary tributary to Portage Lake is the Sturgeon River. The Susquehanna and Tidewater Canal between Wrightsville, Pennsylvania, and Havre de Grace, Maryland, at the head of Chesapeake Bay, provided an interstate shipping alternative to 19th-century arks, rafts, and boats plying the difficult waters of the lower Susquehanna River.  Built between 1836 and 1840, it ran 43 mi along the west bank of the river and rendered obsolete an older, shorter canal along the east bank.  Of its total length, 30 mi were in Pennsylvania and 13 mi in Maryland.  Though rivalry between Philadelphia, Pennsylvania, and Baltimore, Maryland, delayed its construction, the finished canal brought increased shipments of coal and other raw materials to both cities from Pennsylvania's interior.  Competition from railroads was a large factor in the canal's decline after 1855.  Canal remnants, including a lock keeper's house, have been preserved in Maryland, and locks 12 and 15 have been preserved in Pennsylvania.  A copy of a detailed survey blueprint of the entire canal system including structures and property ownership details was donated (date unknown) by the Safe Harbor Water Power Corporation to Millersville University (assessed on 10/06/2016 in the MU Archives at Sp.  Coll.  Map 386.409748 S128 Folio).  The survey consists of 67 pages, 98 x 30 cm.  and is undated but the assumption is the original was created while the canal was in use. The Old Indian Agency House is located in Portage, Wisconsin.  It was added to the National Register of Historic Places in 1972.  The house is located near the Portage Canal. Indian Island is an Unincorporated community in Jefferson County, Washington, United States.  The whole island is covered by the Marrowstone CDP.  It is located between Port Townsend Bay and Kilisut Harbor.  Parts also border on Oak Bay and Scow Bay.  Until the construction of the Port Townsend Ship Canal (also known as Portage Canal) Indian Island was connected to the mainland by a broad sand flat and backshore marsh.  Indian Island is the location of the Indian Island Naval Reserve, which covers the entire island.  No civilian residences are allowed on Indian Island.  Indian Island is attached to Marrowstone Island, and is often grouped with it.  Indian Island is served by the ZIP code for Nordland.  The entire island has a land area of 11.28 km² (4.3553 sq mi) and a population of 44 persons as of the 2000 census. 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.
