I just spent two days on Lewiston Lake with Al and Emil from Sacramento.  They both caught a lot of fish.  The fish are fairly dispersed right now, but we were able to find some really concentrated pods as well.  Today was pretty incredible with plenty of sight-fishing.  We used indicator nymph and dry/dropper techniques all day.  Al hooked about five fish on dries and most of our grabs came on small black midge patterns.  We didn't find a lot of really big fish, but we more than made up for it with incredible numbers of hookups.
