Flies
Early in the season, the fly rodder fishing a lake at inflowing stream mouths might use a dark nymph, size 12, or a black woolly worm. A sinking head line will be most effective in getting to the fish near the bottom when they are lethargic. A size eight black woolly bugger marabou fly is an effective pattern. [n smaller headwater streams try a weighted stonefly nymph.
As the season progresses, try the black leech or black marabou streamer when fishing deep, or an Adams, or Irresistible dry fly, or a Blue Winged Olive when fishing ,mall brooks. If the brook passes through a grassed meadow, try a deer hair black ant, a black cricket, or a grasshopper pattern. Caddis fly patterns, whether dry fly or emerger, are deadly in small waters because these insects have an affinity for slightly acid waters like those draining from a beaver pond. For larger fish holding near a structure in a pool, a streamer fly imitating a minnow might do wonders.
Effective wet flies are many, but the bright colorful ones like the yellow Sally, Paramachene Belle, and the scarlet Iris were developed in North America especially to take brook trout. However, dark-colored flies like the hare's ear and muskrat wet work better in some situations.
