Keep moving around by the bridge.  There are quite a few fish in that area.  They seem to pod up in different areas depending on the flows.  They are in faster water than you would think.  Try some micro mayflies and olive RS-2s and use a AAA weight.  Keep a mental note on where you get bites or catch fish.  My mental database has hundreds of little rocks and dropoffs where fish hang out all along the creek. 

Fishing with Bono will cut your learning curve considerably.  Once the creek gets busy the bridge area is no fun to fish, unless you enjoy people casting over your line.

Hi again all, managed to get up to Putah for a couple of hours late Sat afternoon. Scoped out #5 for a while as I'll head up there Wed morning and then headed up to the Bridge area for some more practice. It was pretty busy and I walked by 6 or so people before finding a spot that looked okay. Tossed a san juan worm with a micro may dropper to no avail for about 20 min. I adjusted depth & casts before switching to a caddis nymph with a copper john dropper.

Meanwhile another guy stopped by about 50' downstream and after making a few changes caught one in less than 10 min! After landing another 3 or so he packed up to move on and I asked im what I was doing wrong vs what he was doing right. He gave me some great tips inluding switching the dropper to a brown mayfly nymph (I think !) that I had in my box. After 5 min in his spot with a few depth adjustments I hooked and landed my first fish on a fly and I was thrilled. It was an 11" planter and I ended up with 4 to hand and 2 lost, one of which fought like a madman for a few seconds and bent the hook!

Attached is the pic of my first fish, I didn't notice the pull tab in front of the reel when I took the pic but perhaps it's appropriate for the bridge area before the clean up! I noticed that all 4 fish looked a little beaten up and each had the left pectoral fin smaller than the right and one was raw - do the planters all swim clockwise in a tight tank?

I'm so grateful to everyone here (and mystery guy - I didn't get his name) for the great advice - I'm now completely hooked on fly fishing and can't wait to fish Putah in the winter Shon42073!

congratulations! Well done, can't believe you hooked up in just two trips. Wait till you hook the big one
