The Lower Sac fished well for us today.  My clients Tom and Barry from Bakersfield caught fish on nymphs and dries.  Tom started the day off with a 20" rainbow on his 2nd cast.  The dry fly fishing wasn't red hot, but it was pretty good.  There is a mixed hatch of caddisflies and PMDs.  We also saw some callibaetis later in the day.  Barry landed a 16" rainbow on a dry.  We even hooked four fish side-drifting dries Montana style.  With the low flows we have right now, it's not a long trip up to the top for the fish.  When they're looking up, you can do fairly well blind fishing dries.
