The Lower Sac is fishing great right now.  I just finished 3 days in a row.  The 1st day was slow, but the last two days were fantastic.  We caught lots of big fish 18-21 inches and today we lost one that was 5-6 pounds!  Some of the 20-21" fish are three pounds.  The egg grab is really good.  There are a lot of salmon spawning and the big fish really want to eat those eggs.  We also caught a lot of nice fish on dry flies in the afternoon yesterday.  Fish are looking up for big caddis dries right now.
