In order to get to LakeHuron, we have to negotiate the Soo Locks which were began in 1852 and have been expanded  many times.  The latest being in 2019 with the expectation of finishing by 2029.  The interesting difference here is that no pumps are used to fill or empty the locks, only gates and chambers-gravity moves the water.
