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.
North Walsham &amp; Dilham Canal The North Walsham and Dilham Canal is a waterway in the English county of Norfolk. It was authorised by Parliament in 1812, but work on the construction of a canal which ran parallel to a branch of the River Ant did not start until 1825. It included six locks, which were sized to accommodate wherries, and was officially opened in August 1826. It was 8.7 mi long and ran from two bone mills at Antingham to a junction with the River Ant at Smallburgh. It carried offal for the bone mills and agricultural products, as it proved cheaper to land coal on the beach at Mundesley and cart it overland than to use the canal.
