Complete your fly box with having a couple of Muddler Minnows in it. These are extremely popular and is a known pattern to catch just about any fish that wants a meal. It has been my favorite streamer since I was a young boy and it is my American Express Card... I never leave home without it. It perfectly imitates a Sculpin. And even if you don't have Sculpins in your water try this pattern. Fish can't resist it. All streamers are lead weighted to get your fly into the water column quickly.
