~1/2 of mainstem 1060393 is an artificial path that drains internal sink divides. The result is many flowlines without a divide.

Solution:

Remove flowlines:
10152753, 10152754, 10126589, 10125886, 10125883, 10125884, 10125885, 10126574, 10125887, 10126657, 10126458

Change Topo:

• Divert into Natural Channel rather then artificial path
  10125872 --> 10125873

The symbolized red line does not have a member divide, the highlighted red line flow to the 10001167, as does 10001155

** Solution**

• Remove flowpath 10000441

Change Topo:

10000635 --> 10001228

Change Mainstem:

ID: 10001228 to 1135798

Here there is a flowline that is not associated with a divide that acts as the terminal flowpath.

Solution:

Merge: flowpath 10046993, and 10047551.

New ID is 10047551 with a toID of NULL

@dblodgett-usgs, all of these (expect 1) can be traced back to the reference fabric... would you like a PR fixing them or is that considered final?

from hydrofabric.

I don't have a good system to incorporate changes other than those from the NWM 2.1 and E2NHD right now. Can you create a set of edits for the next version of the fabric though? I'm working on revamping that step with the existing set of edits in the next bit, so chat me up about how to structure the changes.
