Yes, but it is unlikely that the whales would be eager to share a confined space with the thrashing screws of a large freighter (a large number of which barely fit into the locks) and I suspect that a whale entering an empty lock would tend to cause the lockmaster to suspend operation until the whale exited downstream.
