OSM River Basins

It does have some problems. The upper McKenzie River in Oregon is shown as separate drainage since there is a break in the river. There are multiple sections in that area that are separate. Bigger one is that the Columbia River is split at McNary Dam.

I'm not sure what needs to be fixed in OSM.

Maybe it needs to detect dams. Or rivers that don't end in the ocean or endoheric lake.

Some rivers (especially in the US) miss their waterway-line through lakes/reservoirs and the part crossing the dam. These need to be added.

Edit: https://wiki.openstreetmap.org/wiki/Rivers Explains it quite well with some graphics.

(I'm the creator of this) Yes lots of rivers are missing those sort of connections through lakesᵉᵗᶜ, but that's not unique to USA. Please keep mapping to fix up things.
