I've fished all forks of the Kaweah River. It depends what you want to catch. Personally, I would fish the Marble Fork to get further away and hunt the wild fish primarily. That's what I'm into. However, this time of year I would fish the upper Kings above Pine Flat Reservoir; drive till the road ends and hike further up. I would wait till late summer or fall to fish the upper Kern above Johnsondale - it is out of control on dries then. I've been sticking to local mountains lately as I have a cabin in GVL. If you like to hike there are many good spots that are going off right now on dries. No stockers, all wild fish. My next trip north will be to Mammoth in June - there are millions of creeks to access. I don't bother with the lakes, creeks are more fun. Anybody know where I can get a cheap canoe?
