Yesterday, I fished Putah from about 1:30 to 4:30 pm.

There was some surface and sub surface activity in the lanes 40 to 50' past the shore on the upstream section above the bridge.

I tried my go to fly in N California and SW Oregon, a Yellow Jacket fly, size 6 that hangs down about 12 to 18" of water.

Again I was using my Sage 5120 Spey Rod, the Skagit 450, 15' Air Flow floating tip, and a Rio 15' leader.  I first tried 4# fc tippet.  I missed a few fish, and then a elongated football with fins struck. When I got it about 20' out, it just rolled sideways into the current and snapped the tippet in the middle.  This is an old trick of the wise and big trout in Putah.  I had another repeat with the same rigging.

Then, I went to 6# tippet.  That was the end of the big trout striking and hooking themselves .  The good news I had several hook themselves in the 12 to 16 inch range.  All were beautiful native rainbows.

At about 3:30,  a small caddis hatch was happening.  I went to a size 18 Elk Hair Caddis with a brown wing and a gray-brown body.  The fish were in a lane 50' from me and down stream about the same distance.  At those distances, the fish have to hook themselves.  About every 10 to 15 minutes I hooked and released a nice native rainbow from 14 to 16 inches. One brown of about 14 inches hooked itself.  The biggest rainbow at about 18 inches hooked itself in the side after it missed the fly twice.

At about 4:25, the wind shifted to the west and the cold front moved in.  As usual the woosey trout at Putah stopped striking when a cold front moves in. I called it a good day and left.
