Which is farther north, Lehigh Canal or New Orleans Outfall Canals?
New Orleans Outfall Canals There are three outfall canals in New Orleans, Louisiana – the 17th Street, Orleans Avenue and London Avenue canals. These canals are a critical element of New Orleans’ flood control system, serving as drainage conduits for much of the city. There are 13 mi of levees and floodwalls that line the sides of the canals. The 17th Street Canal is the largest and most important drainage canal and is capable of conveying more water than the Orleans Avenue and London Avenue Canals combined.
Hulme Locks Branch Canal The Hulme Locks Branch Canal is a canal in the city of Manchester. It is 200m (one furlong) in length and was built to provide a direct waterway between the Mersey and Irwell Navigation and the Bridgewater Canal. The canal opened in 1838 and was superseded in 1995 by a new lock at Pomona Dock 3. As both of its locks remain closed, the canal is now overgrown.
