The temperature has really dropped here in northern California.  The weather turned cold today, with high winds and highs in the 60s.  That didn't stop our fishing, though.  I guided Jerry and Kevin, a father and son team from central California the last two days at Clearwater Lodge.  We started with a day on Fall River, where Kevin landed a couple of really nice rainbows.  We had good dry fly action on a black caddis size 14 in the morning.  We switched to nymphs when the wind came up right after lunch.  Action wasn't red hot, but we caught numerous small fish and our two big fish on a size 16 beadhead pheasant tail under an indicator.  Today we fished Hat Creek and Baum Lake.  With the cooler temps there weren't any bugs on the water on Hat Creek until about 10:45am.  We had a one hour feeding frenzy during the trico spinner fall, and then the wind really came up.  Jerry landed some good Hat Creek fish on trico spinner patterns.  We finished off the day at Baum Lake, where the rainbows and browns were chowing various mayflies on the surface.  We say PMDs and callibaetis, but the fish really wanted the incredibly small baetis that were hatching.  A size 20 parachute adams did the trick.  FYI, Baum Lake is a little high and Hat Creek is a little off color because the Hat Powerhouse #2 is off-line.  The water is being shunted down the steep emergency chute next to the powerhouse, so there is quite a bit of debris coming down through the powerhouse riffle.  PG&E seems to be working frantically, but I don't know when things will be back to normal.  Hat Creek is plenty clear enough to fish, though.
