Stay Within The Lines: Casting Angles for Nymphs and Streamer
Winter is upon us, which means I’m fully engaged in streamer tactics. It’s not because streamer tactics are the best approach this time of year -- if you want to catch fish, nymphing will likely yield better results -- it’s more because I love to work streamers, hungry for that elusive tug, even if it means going all day without a strike. I welcome that challenge! In late February/early March, when the first olive hatch occurs, I enter into a different mode, but the tug is hard-wired; I go back to it at every opportunity.
One cold April morning, trout still positioned deep in the water column and stubborn to any offering, my friend and Master nymph fisherman, John Stoyanoff said: “You can’t dictate to the trout; you take what they give you.” John noticed that I was casting my nymphs more over and across than up. The result was that drag was setting in early and my nymphs were lifting off the streambed. My presentation was too fast for the lazy trout. John’s upstream casts were more in line with the current, and his nymphs reached (and stayed) deeper in the water column. Eventually, grannom pupa began to emerge, and the trout, now active, would consider my over and across, tension cast.
The correct angle of cast made the difference. A big difference. Casting in line with the current slows down and deepens the drift. The over and across cast creates almost immediate drag and speeds up the offering. This makes for a long day of presentations to finicky trout. Tensioned casts have their uses, but they are useless to trout holding in cold, deep water. They aren’t looking up until an emergence, some activity, occurs.
These rules apply, especially in cold, winter months, to streamer tactics too. Yes, trout will run down a streamer during a polar vortex, but cold water temps often result in less active trout. So when water temps decrease, so does the speed I work streamers. This means casting more “in-line” with the current. The goal is to reduce drag and keep your patterns in likely “lanes,” where trout will position. The choice of a correctly weighted streamer, or the right sink rate for fly line are important choices, but the angle of the cast greatly influences how slow and how long a pattern remains in a trout’s ambush zone. Remember, let the trout tell you how how active you can fish your streamers. As a general rule for winter streamer tactics, slow your presentation. I tell my 8 year-old, in his frenzied, crayon sessions, to “STAY WITHIN THE LINES.” Like most parents, though, I am an infrequent listener to my own advice!
