I took an overnight cruise through the locks there. When they pack the cargo ships into those locks, they just run them into each other, sparks literally flying as the hulls scrape together. I vaguely recall there being 5 other ships alongside our cruise ship.

Along the cruise, we toured one of the artificial ghost towns the government built for the population that was displaced by the dam. The only people in sight were the convenience store clerks at the dock, trying to sell to us tourists.
