Question: What canal is located more westward in the US, the Florida Canal or the Pioneer Canal?
Context: Pioneer Canal is an irrigation canal in Kern County, California, United States.  It originates from the Kern River just east of the Stockdale Highway bridge.  It terminates at reservoirs just east of Interstate 5 (Westside Freeway). The Baltimore and Ohio Railroad is the oldest railroad in the United States and the first common carrier railroad.  It came into being mostly because the city of Baltimore wanted to compete with the newly constructed Erie Canal (which served New York City) and another canal being proposed by Pennsylvania, which would have connected Philadelphia and Pittsburgh.  At first this railroad was located entirely in the state of Maryland with an original line from the port of Baltimore west to Sandy Hook.  At this point to continue westward, it had to cross into Virginia (now West Virginia) over the Potomac River, adjacent to the confluence of the Potomac and Shenandoah rivers.  From there it passed through Virginia from Harpers Ferry to a point just west of the junction of Patterson Creek and the North Branch Potomac River where it crossed back into Maryland to reach Cumberland.  From there it was extended to the Ohio River at Wheeling and a few years later also to Parkersburg, West Virginia. The Augusta Canal is a historic canal located in Augusta, Georgia, United States.  The canal is fed by the Savannah River and passes through three levels (approximately 13 miles total) in suburban and urban Augusta before the water returns to the river at various locations.  It was devised to harness the water power at the fall line of the Savannah River to drive mills, to provide transportation of goods, and to provide a municipal water supply.  It is the only canal in the US in continuous use for its original purposes of providing power, transport and municipal water. Landsford Canal State Park is a South Carolina state park located in Chester County, two miles (3.2 km) from US 21.  The 448 acre park contains the ruins of the Landsford Canal built to bypass rapids on the Catawba River using slave labor between 1820 and 1825.  The coming of the railroad caused the canal to be abandoned.  The former lock-keeper's house contains an interpretive museum.  In addition to the canal, visitors also can see one of the largest remaining stands of "Hymenocallis coronaria", the Shoals spider-lily, that grows in the shoals of the river, and bloom mid-May through mid-June.  The park offers hiking, picnicking, boating, and fishing. The Canal Lauca is an artificial channel to divert the waters of the Lauca River westward through a canal and tunnel into the Azapa Valley for purposes of irrigation in the valley and hydroelectric-power generation.  Its construction began 1948 and water diversion began 14 years later from a dam located about 16 miles southwest of Lago Cotacotani Lake. The Florida Canal or 40 Arpent Canal is a canal in the New Orleans metropolitan area and land down river. The Atlantic and Mexican Gulf Canal Company was a canal project approved February 23, 1876 and owned by Joseph E. Johnston, General Lafayette McLaws and Joseph Shepard of Georgia, and others.  The purpose was constructing a canal from the St. Marys river in Georgia, across the Okeefinokee Swamp, and thence westward by the most direct and practicable route, as the company may determine, to connect with the waters of the Gulf of Mexico on the coast of Florida, for the purpose of transporting from the Atlantic to the Gulf along the route indicated, and to market on either side, the timber, lumber and other products of the country, and other commercial products as may be offered, and the convenience of the route may determine of may attract to it. State Road 700 (SR 700) is the mostly unsigned Florida Department of Transportation State Road designation of US 98 between Chassahowitzka (where US 98 continues northward as unsigned SR 55) and Twentymile Bend (where US 98 continues eastward as signed SR 80).  The only segments of State Road 700 that are signed are between SR 50A and US 41 in Brooksville, and from Okeechobee south, through Canal Point, to SR 80.  From the northernmost signed point, it's an unsigned concurrency with SR 45(US 41), then with SR 50, before rejoining US 98 at the west end of the US 98/SR 50 concurrency.  The section between Canal Point to SR 80 is signed only as State Road 700 since the relocating of US 98 to run concurrent with US 441 in Palm Beach County. Lake Tohopekaliga Tohopeka ([from tohopke /(i)to-hó:pk-i/ fence, fort]); Tohopekaliga [from tohopke /(i)to-hó:pk-i/ fence, fort + likv /léyk-a/ site], also referred to as Lake Toho, West Lake, or simply Toho, native name meaning "we will gather together here", is the largest lake located in Osceola County, Florida, United States.  It is the primary inflow of Shingle Creek, which rises in Orlando.  It covers 22700 acre , and spans 42 mi in circumference.  It is linked to East Lake Tohopekaliga by Canal 31 (St. Cloud Canal).  The canal is 3 mi long and runs through western St. Cloud.  South Port canal is located at the southern tip of the lake and links it to Cypress Lake.  It is 4 mi long.  Lake Toho is bordered on the northern shore by Kissimmee, on the eastern shore by Kissimmee Park, and South Port on the southern shore.  Lake Tohopekaliga is known for its bass fishing and birdwatching.  Lakefront Park is located at the north end of the lake and borders Lakeshore Blvd.  Lakefront Park has a scenic walking path with benches where visitors may view the area's wide array of waterfowl, alligators, turtles and others.  Lakefront park also has a miniature lighthouse, a children's playground area, and is bordered on its west end by Big Toho Marina. The Canaveral Barge Canal provides an east-to-west link between the Atlantic Ocean and Indian River Lagoon across northern Merritt Island, Florida, in two segments separated by the Banana River.  It is located 15 miles south of Titusville, Florida.  The canal is 12 feet deep and has entrances to other water systems including Syke's Creek and various marinas.  The canal links Port Canaveral along the Atlantic Ocean to the Intracoastal Waterway running down the center of the Indian River Lagoon.  The canal was constructed to allow the transport of crude oil by barge to the two power plants south of Titusville, Florida.
