Seeking Kern River info

I intend to fish the Upper Kern above Kernville, including the special regs
section above the Johnsondale Bridge next weekend. Any suggestions on flies
and tactics for this time of year would be appreciated. I usually fish from
the Forks of the Kern upriver on both the Kern and Little Kern and I
haven't spent much time on these lower sections of the river. My best guess
is little yellow stoneflies in the riffles, but more experienced input would
be great.

TIA,
Danl
