This time of the season, dry fly fishing in the streams and creeks surrounding West Yellowstone is at its peak. July and August are dry fly months as there is a tremendous amount of food available to the trout, both aquatic insects and terrestrials. While we do have a lot of match the hatch fishing or trout feeding consistently on the surface to landborn insects, a lot of our best dry fly fishing is attractor fishing. Using a dry fly to cover likely water is an extremely effective way to fish our rivers, but it requires a bit different approach and fly selection than casting at rising fish.
Attractor dry fly fishing is very effective in this area for a number of reasons. First off, most of the rivers we fish in Yellowstone and Montana are simply not very deep. Trout don’t have to charge out of the depths to eat a fly on the surface. In fact, many large fish can be found in under a foot of water if not disturbed by anglers. The second reason that dry fly fishing can be a deadly method for probing the water is that many different types of trout holding water can be fished well with dries. Nymphs tend to hang up in shallow pools, get stuck in weeds, and snag logs and rocks that our trout use for cover. Dries just drift by or over this structure. This allows a dry fly fisher to fish water that others simply don’t want to bother fishing. Dries also make the least amount of disturbance when they enter the water and don’t spook fish when they land. Lastly, dry flies work great because many anglers simply won’t fish the surface unless they see fish rising, so trout get bombarded by nymphs in many places.
By following a few simple ideas, one can increase the number of fish that will be brought to the surface. First off is fly selection. Picking the “right” fly, or the only one that trout will eat is seldom a consideration. However it is a good idea to loosely match the size and color of the insects that fish are most likely to see. Fishing a fly that is visible at all times is also crucial. If you can’t follow the drift of the fly to see subtle rises, the chance of success in hooking any trout that rise decreases greatly. At times, going to large, white winged flies like Trudes or Wulffs is the only way to keep the flies in sight. Don’t worry, one will hook and land more fish casting a size 10 Trude that is visible than a #16 Beetle that is not. Seeing the fly is that important. Parachutes and ParaWulffs, Stimulators, Trudes, Wulffs and other hair wing dry flies are effective patterns because they offer realistic silhouettes to the fish, float well, and remain visible. If fish aren’t rising to the fly you are fishing, by all means change it up. Size and fly design do make a big difference. Changing from a #14 Rusty Parachute from a #14 Parachute Adams probably isn’t going to make a big difference. Tying on a #16 Royal Stimulator or Tan Elk Hair Caddis instead of the Adams can however make a drastic change in the success of the angler.
Another crucial element to attractor dry fly fishing is getting a good drift. We all know the importance of a good drag- free drift when fishing to a trout that is steadily rising. When fishing the water, the same perfect dead drift is required. Look at each line of drift you intend to fish, figure out where the flies, leader and fly line need to land in order to maximize the float of the fly and make the first cast count. Fish become MUCH less willing to rise after a fly has drug or skated over them. This is especially true on heavily fished rivers like the Madison, but applies everywhere by late in the summer.
Don’t try to fish all the water with the same angle and presentation. Most slow water on the river’s edges can be fished with an upstream cast. A reach cast that places the fly line into slower water than the fly lands in is helpful in achieving a nice long float. A rock slick fished in the same manner only results in nearly instant drag as the fast water at the bottom of the slick quickly pulls the fly line, yanking any slack in the leader and pulling the fly downstream. A down and across cast where the fly lands downstream of the fly line is much preferred when fishing this type of structure. Casting over the bank and using rocks and logs to hold the fly line off the water can also be very helpful at times. Be creative in how you fish each spot, you will learn a lot about drift and see better results.
Covering as much water as possible is the key to raising numbers of fish. Most trout cannot be induced to rise by casting over them repeatedly. They will eat the first good drift they see or not eat at all. That is good news to the angler, as he or she can make a good drift or two over a spot or feeding lane and move on. The beauty of attractor fishing is that it allows an angler to cover so much water. Keep the casts short and controlled, maximize each float and rapidly fish every likely spot. Keep moving! By fishing in this manner the angler is constantly putting the fly over fresh fish that are unaware of his presence and have yet to see a sloppy drift. If a spot proves too hard to properly drift the fly after a few attempts, just move on.
Next time you are on the river, try fishing an attractor. Fish a visible fly, get good drifts, cover a lot of water and see what happens. You may be pleasantly surprised at the results.
