The North Fork of the Yuba river is an amazing river. It hold loads of wild Rainbow Trout as well as some Brown Trout.
Some of the tributary rivers include : Lavezzola Creek, The Downie River, Pauley Creek, Butcher Creek, Haypress Creek, Milton Creek, and Salmon Creek. These creeks are full of small and hungry wild trout.
Fishing these small streams is generally best done with a light and short fly rod with a short leader…something like a 8 foot 3 weight rod with a 7 1/2 foot leader on a floating line. The name of the game is to keep moving- cast a few times and move to the next pool.
