Great map! The whole aqueduct is higher than the river and the water is going the wrong way was really bugging me until I looked at it again tonight and suddenly realized that the water in the river is flowing from right to left not left to right as I initially misinterpreted it, and the water fall is falling down into the river and agueduct and not the other way around. IT.SUDDENLY.MAKES.SENSE! Damn, I'm slow!
