Describe the data problem
More detail in this issue on the frontend repo: sdl60660/river-runner#28. Many rivers in western/central Canada seem to be over-aggregated and incorrectly assigned to a few particular features (St. Mary's River, Red River of the North, Rainy River). Oftentimes, this seems to be linked to name changes that occur after a large inland feature (opposed to a confluence).

Suggested fix
The commenter in the linked issue submitted a table of suggested fixes, but the issue here appears to be a larger systemic issue that probably won't be easily remedied by making one-off fixes.

I think I see what's wrong. Should be fixable actually. Application of NHDPlus US names looks like it was a little overzealous.

OK, so the naturalearth name is now over being used outside the US. See the image below - just north of the boarder, it's just "Red" and not "Red River of the North" as is the name south of the boarder in the NHDPlus.
