Awhile ago a friend whose dad is a hydrologist for the USGS was trying to explain to me that the Yuba doesn't have any forks and that the correct place names are North Yuba, Middle Yuba and South Yuba. I didn't quite follow her explanation and had forgotten about it until I was driving up 80 the other day. As I crossed one of the bridges it was labeled "South Yuba River".
Can anyone lend any insight on this question?
