Since Jim "Coz" Costolnick began his guiding career on the Upper Delaware he has logged tens of thousands of hours guiding this river system. Coz was the original a host of ESPN's "In Search of Fly Water" and traveled the globe to bring the world of fly fishing into the living rooms of millions. Coz is currently a fly fishing field staff advisor for the Pennsylvania Outdoor Life television series. Coz is a certified casting instructor and Pro Staff advisor for the Clacka Craft Boat Company. Coz's love of sharing his secrets and techniques is what makes him a highly sought after teacher, speaker and personality in the fly fishing industry. When he's not on the water he can usually be found at his fly shop, Border Waters in Hancock, NY. Coz also hosts our annual Steelhead Camp on the Great Lakes tributaries. His dedication to the river is displayed through his work on the board of directors of Friends of the Upper Delaware River.
