 Joe Fowler, Disneyland's construction supervisor and a former navy admiral, insisted on creating a drydock for the ship along what was to be the Rivers of America.Walt Disney, dismayed at how much land was taken up by the massive excavation, referred to the drydock first as "Joe's Ditch", and then later, "Fowler's Harbor", the name by which it goes by today.However, Disney remained a supporter of the riverboat itself, funding its construction out of his own pocket when corporate funds fell short.
