FYI to anyone interested. Drove back from fishing in the Winthrop area on Monday over SR 20. Saw a phenomenal hatch coming off on Diablo Lake in the shallows right near where the road crosses it. Didn't have time to assemble my gear but took 5 minutes to observe the frenzy and I could clearly make out that some of the 20 - 30 rising fish were trout(bows or cutts I guess). If anyone is up that way soon it might be worth a stop. I'm going to try and find a day in the next week or two to check it out so I'll report back when I do.
