If the direction of a waterway is not determinable, this doesn't mean
our definition is wrong. You might still get it also in unaccessible
areas by looking at the elevation of the terrain. If you absolutely
can't get it, just add a remark to the object.

In the case you posted you could stand on Eastbrook Boulevard and see
in which direction it flows.
