Abstract

A canal lock system for recirculating water between a reservoir and canal lock that uses air pressure to change the water level in the canal lock. The canal lock system comprises at least one canal lock, at least one reservoir for holding recirculated water connected to the bottom of the at least one canal lock, and at least one air pump connected to the at least one reservoir for pressurizing the at least one reservoir with air to force the water into the at least one lock to thereby change a first water level in the at least one canal lock to a higher second water level, wherein the at least one reservoir maintains a constant volume and wherein the at least one reservoir is depressurized to thereby change the second water level to a lower third water level.
