What a difference two days makes!  The water color on the Lower Sac has gone from clear a few weeks ago to a nice steelhead green to a very bad brown today.  The speculation is that Lake Shasta is browning up either from the ash flow coming down the McCloud or from erosion from the exposed banks of the extremely low reservoir.  We'll keep you posted on the water conditions but for the time being I would steer clear of the Lower Sac.
