Suggested change for Reference Topology 10L

Where does it occur: VPU 10L near the North Platte River Authority Airport Mainstem ID: 1107638 (ID: 10023804)

What is the issue: There is a flowpath (red) that is part Fremont Slough AND part Natural channel (South Platte Tributary), The natural channel is the mainsteam (1107638), however the topology flows to the slough that exits the flowpath mid segment

This leads to one of the only cases where a mid segment exit occurs and looking at the context, seems incorrect. Although no simple solution may be ideal:

Possible solutions:

Change the toID of ID:10023804 to 10023793. This would continue the flow on the mainstem and drain to the Platte

Or

Change the mainstem of 10023804 to 1142381. This would place this segment on the Fremont Slough

Or

Split the flowline is some way to have perpendicular flows running along the South Platte Tributary and the Fremont Slough where the latter is an artificial flowline with no divide.

What do you think?
