The attached pdf shows the basin map output by r.watershed based on a 10m DEM and a threshold of 150000. The NHD level 6 subbasins are outlined in black and the 1:24K NHD streams are in blue.
The small white areas at the bottom left and center right appear to be external to defined sub-basins. But I don't know how to interpret the larger white areas with streams in them (center and top). The top margin is an international boundary so I can understand not being able to completely define sub-basins across that boundary since the DEM doesn't reach that far north, but it's not consistently white. Please help me interpret the white areas with vector streams. TIA, Rich
