To fish the woolly bugger effectively in still water you should utilise the hand-twist retrieve and the count down method for finding the right depth. A strip retrieve is too fast and erratic to accurately imitate the natural flowing motion of a swimming leech. The hand-twist brings the fly in at a steady pace, just like the real creature. The leech is most effectively fished near the bottom of the lake or at the tops of the weeds, whichever comes first. To find this depth use the countdown method .
Scuds make up the other staple of trout in slow water and lakes.
These little crustaceans are often referred to as freshwater shrimp, but they are not really shrimp. Hyallela occur in both coastal and interior lakes, but the big Gammarus prefer alkaline waters and don't occur much on the raincoast. Either way, the scud is a very important food staple of trout and while there are many excellent imitations of it, the Crystal Scud is one of the easiest and best patterns I know. Wrap on tying thread and secure to the butt a length of crystal chenille. Wind thread to the head and wrap chenille to just behind the hook eye.
