This lock stand stands out among all the system locks because it’s actually two locks built in series. The downstream gates of the upper lock serve as the upstream locks of the lower lock. The two locks were built one after another because of the drastic drop in river elevation at this location.
Please note that a lock’s phone (and voicemail) is only monitored during its operating hours.
