Re: Effective small pond fishing
Your floating line should work fine, especially during the spring- bass and bluegill are spring spawners, and tend to stay shallow and close to the bank until the heat of the summer. They're also structure-oriented fish- brushpiles, beds of submerged or emergent vegetation, docks, buoys, overhanging brush or vegetation, standing timber, rock piles or riprap, boulders, and other features tend to concentrate them. Focusing on any of those areas (if they're present) will help. Cast your fly, let it sink a few seconds (watch your line and leader, fish will often grab the fly as it's sinking). Then begin stripping it in- vary the speed and retrieve until you find the pattern which the fish best respond to.
As far as patterns to use, wooly buggers and mohair leeches take plenty of bass. Soft hackles work well, too. Surface poppers and sliders can be a lot of fun in the warmer months. Flies which imitate damselfly and dragonfly nymphs, crayfish, and minnows tend to be very effective- the Carey Special, Whitlock's near-nuff sculpin, zonkers, clousers, marabou muddlers, and others work well.
