@zarian2 Based on the illustration it doesn't look like it, but who knows. It's just that if they need to build both the boats and the locks, it would have been easier to just build the boats in a place where such locks wouldn't have been needed. If they are needed everywhere, the river would be nigh useless for boats, and Haurelia would surely notice the new locks. However, I don't think that's the case, especially since the east is supposed to be flat lands.
But sure, I do agree that it would be nice to see the dams to be connected to something surprising instead, as long as the surprising maneuver makes perfect sense. Flooding makes perfect sense if you can pull it off.
