Here are a few other tips that might work: - Look for things like locks, spillways, bridges, etc. that would cause whitewater and use that to determine flow direction - Rivers and streams tend to flow toward larger waterbodies, such as lakes, gulfs and oceans. Look for things likes deltas to help determine flow direction - Also, they tend to converge with other rivers & streams downstream. Look for the Y's where two rivers converge, with the being toward the base of the Y - Rivers and streams tend to be wider downstream. - Because of above, larger navigational vessels tend to be found downstream - Because of the above, larger settlements tend to be found downstream.
Of course, these are general rules of thumb and there are exceptions. For example, a river might widen into a lake and then have a narrow stream flowing from the lake. Likewise, dredging may artificially widen a river segment between two industrial centers. Still, I think these rules along with Blake's tips should get you most of the way there. Hope it helps!!!
