Define "land locked harbor". Is the Port of San Francisco "land locked"? If the fact that it's on a bay that is DIRECTLY connected to the ocean means you don't consider it "land locked", then how about the Port of Chicago, which is on a lake, but with a navigable path to the sea both via the St. Lawrence Seaway and the Mississippi River, along with assorted canals and locks? The Great Salt Lake Marina is pretty definitely land locked, but I'm not sure it counts as a "harbor" since I don't think there's any shipping through it.
