Wikipedia says that Senusret III specifically stopped building the canal due to the height differences. Ptolemy II later had locks built. Though this was also a canal to the Nile not the Mediterranean and so they were concerned about the salt water mixing with the lower and Nile water. Maybe navigation wasn't a concern. https://en.wikipedia.org/wiki/Canal_of_the_Pharaohs |
