All upstream of catchments (Watershed)

[jbousquin]

I'm looking for suggestions as my current approach is slow and hitting the new rate limit.

I have a set (~1600) of NHDPlus v2 catchment comids for an area and am trying to rebuild the network locally for these comids and any upstream. I'm using nldi.navigate_byid(fsource= 'comid', navigation='upstreamTributaries', distance=9999, source='flowlines') and looping over the comids for the fid arg. In that loop it skips the comid if it were returned in a prior result (i.e., it was upstream of a catchment already run). I don't use the geometry returned, just the comids. Any suggestions on a better way to do this w/ pynhd?

For navigating NHD v2 locally for large scale applications, you can refer to this tutorial. Hope this helps.
