I had a really fun day on the Lower Sac today with Mike from Sacramento.  The nymphing started out a little slow, but by lunchtime the fish were eating egg patterns, rubberlegs, and various mayfly nymph patterns regularly.  From 1 to 3pm we had some excellent dry fly fishing.  We rose about a dozen fish from 10 to 16" on dries.  The main hatch was a PMD size 16, but there were also good numbers of caddis on the water.
