I spent a few hours on the Lower Sac today with fellow guide DJ Spivey.  The river has been at a stable 4100cfs flow for a week now and fishing is pretty good.  The first salmon are starting to dig redds in the upper end of the river and we found a couple trout already willing to eat an egg imitation.  Most of our action was on normal flies, though.  There wasn't much of a hatch today and it seemed like the fish were open to suggestion.  We caught fish on everything from a size 6 rubberlegs down to a size 18 mayfly nymph.  Our first fish was a kype-jaw 20 inch brute.  For quality and quantity, the Lower Sac is pretty hard to beat right now!
