Randy Hamann rowed me down the river today for a fun day off.  The Lower Sac is at 20,000cfs and fishing is pretty darn good.  There is a lot of water that isn't fishable, but the higher flows open up a lot of great water that usually is high and dry.  Our morning was a little slow, but mid-day was excellent with plenty of fish coming on cheese brains and assorted mayfly nymphs.
