We’ve fished the Upper Williamson River in Southern Oregon at Yamsi Ranch several times….a really fun place to fish for native brook trout and rainbows.  Sometimes its amazingly easy, other times it can be quite challenging.  Here is Mary Ann working a nice rainbow under a submerged tree with a small streamer.  She was using my 8′  0″  5 wt Slow-Action Spring Creek rod this day.
