When it comes to casting topwater flies for summer smallmouths, remember these words: Go. Slow. That’s the advice of guide Nate Sipple of the Tight Lines Fly Fishing Co. (tight lines fly shop.com) in DePere, Wis. “If there’s one thing I have to remind my clients to do, it’s to slow down,” Sipple says. “Let the fly hit the water and sit for several seconds, then give it a single sharp, definitive pop. Let it sit, pop it sharply again, and so on. The lower and clearer the water, the less you should move the fly.” —T.D.
