My brother and I will be fishing Putah Creek in late March.  I've fished the creek once before with Jordan Romney about 2 years ago.  We plan to fish on our own this trip.  We both fly fish quite a bit, and call the White and Little Red River our home waters here in Arkansas.  I'm looking for any advice as far as catching fish, but also staying on the right side of the law/ethics.  I'm aware the spawn has been on but by that time should be mostly wound down.  Of course we'll still keep an eye out for any redds.  We deal with the same issues on the Little Red at home, at Cow Shoals with regard to our wild brown population.  I'm not familiar with California regs, so any advice regarding setups would be welcome.  Our typical rig is a two fly rig with split shot above the point fly and an indicator, which is what I recall fishing with Jordan.  I saw where dropshotting may not be legal, and if there's any other techniques or specifics I'm all ears.  As far as flies I've studied the forum, and feel comfortable with the usual assortment of smaller 18 and less mayfly/caddis and even midge patterns.  Any specifics are welcomed, though I know we all have our secrets!  From what I remember the road runs the length of most of the creek, and we can just stop at the turn outs and hike in to the creek.  We didn't fish up by the dam, or in the resort property, mostly down below.  That would be my idea, but again if there are better ideas throw 'em at me.  Thank you in advance for any advice, and thanks for being such strong ambassadors for a neat little creek.  I wish we could have this kind of passion on the Little Red!
