You live in a similar area to mine. Life is good....

For smallmouths, don't use little flies. They like a mouth-full. Try using a brown and orange Clouser Minnow, or Wooley Booger (tie with the hook-up). Just work them over the bottom in short hops, and hang on. If you have any Crawfish Smelly Jelly (or similar product), place a drop on the head of the fly every 20 or 30 casts. Black Woolley Boogers do a good job imitating a hellgramite, another favorite food of SM bass. If all else fails, tie on a# 4 purple Bunny Leech (with Clouser eyes).

For bluegills, nothing beats Richard Komar's Black Widow. Also, any Gorilla Glue Bugs, or Pom-Pom Spiders will trigger murderous strikes from these little scrappers. When the water gets below 65 degrees, they slow down a lot, and won't move very far to take a fly, and they will hit light, so use a strike indicator. Scale-down the fly size to small nymphs, and midges. Buzzers are especially good for bluegills in the winter. Same goes for suckers, darters, log perch, etc....
