I volunteer to do the Rivers/basins map!
The Basins Great Lakes should all be shown as part of the St.Lawrence Basin. (Maybe one day we will have First Level Subdivision borders between basins within basins (like Missouri and Ohio in the Mississippi basin)
The red bit was a border of bulgaria just for a reference point to draw the basin's borders.What is that red bit?
And where are the other rivers of this basin?
And i think the sea of Marmara should have it's own color for it's drainage basin.
(Every sea should have a color for it's seaboard drainage basins)
I think we should focus more on getting more rivers into basins that exist already, instead of drawing new basins.
