Clouser shares the extensive knowledge he has developed over a quarter-century of guiding for smallmouth bass on the Susquehanna River. Beyond his native waters, the lessons Bob offers in this book can be directly applied to smallmouth fisheries across the country, from creeks to large rivers. An experienced teacher, Bob anticipates the questions and challenges faced by anglers when they first encounter a smallmouth stream. He explains the natural history of smallmouth - their range, spawning behaviour, feeding habits, and seasonal movement patterns - and then introduces the specific flies and techniques he uses when fly-fishing for bass. In sections on casting and presentations, he discusses intermediate to advanced methods of casting with weighted flies and lines as well as various surface and subsurface tactics, with dramatic colour photos of the author demonstrating how it's done. It includes advice from well-known anglers, among them Lefty Kreh, John Randolph, and Mike O'Brien, on the greatest bass waters from California to Ontario.
