It can be tough fishing for Smallies here when the water's this cold (about 52F on Saturday, probably colder this week with the cold front --- we've got a chance for snow tomorrow night!).

I'd recommend the following: sinktip or full-sinking line, BIG, heavy flies (Sculpin or Crayfish topping the list), fish slowly in the big pools around structure. You won't catch many this way, but you might hang a really BIG smallie. If the sun comes out and the water warms up some before you get here, you might try some other tactics, but big, deep, and slow are my usual early-Spring tactics for Smallmouth (well, that and tying flies and waiting for April )

Good luck!
