The Lower Sac is fishing red-hot right now.  We had a wide-open nymph grab all day long.  We fished up in Redding today.  My clients Rich and Kathleen caught tons of 14-17" rainbows and landed a couple up to 19".  There were lots of boats around, but the fish didn't seem to mind.  Yesterday we fished closer to Red Bluff and didn't see another boat all day.  Fishing was slower and the fish were smaller down there, but the solitude was really nice, too.
