Rivers in Northern California that allow dogs?

I'm in Sacramento, rivers are really dangerous this year. Sac River allows dogs, as does Feather River (Yuba City area). Russian River, or at least part, is in a town called Guernville......GREAT AREA!!! I'd suggest a lifejacket for your dog this year (always actually), they've already had 28 drownings this yr in Sac & American Rivers. Take CARE!! ENJOY!!
