Fly fishermen know that one of the top warm-water fish to fly fish for is non-other than the smallmouth bass. Summertime Smallies can cruise shallow and especially feed around shallow water rocks and weeds.
Pete Leduc who lives in the Sudbury, ON region knows this well and alternates from fly fishing for Brook Trout to fly fishing for Smallmouth Bass. Top flies to fish when water is a little colder and smallies are feeding sub-surface are leech patterns and minnow imitating streamers. When smallies are shallow and the water is warmer fly-poppers, frog and mouse patterns fished on the surface produces amazing action!
