The MFC (Montana Fly Company) Sheep Creek Special is a classic, all-purpose Western stillwater nymph pattern created for high mountain lakes and reservoirs. Although its exact imitation is debated, it is extremely effective as an attractor, suggesting a variety of food sources like a leech, aquatic snail, scud, or water boatman. This versatile fly is typically fished with a slow, deliberate retrieve on a floating or intermediate line to entice selective trout in still or slow-moving water.
