You might start with DEMs and analyze them for V like paths that 
represent drainage in the terrain. This would give you a starting place. 
Then I suppose you could recruit people that like to hike to collect GPS 
tracks along rivers, streams, ponds and lakes and enter that into a OSM 
server designed to work with hydrology models.
