Fly Fishing the Delaware River

The Upper Delaware system on the New York–Pennsylvania line is the East's premier wild-trout dry-fly fishery, anchored by the cold West Branch below Cannonsville Reservoir, the East Branch below Pepacton, and the larger main stem below Hancock. The West Branch at Hale Eddy runs cold and clear, sustaining self-reproducing wild brown and rainbow trout that key selectively on hatches. These are technical, often big-water fish that reward long leaders and accurate casts during prolific mayfly emergences. The river is famous for its Hendrickson, March Brown, sulphur, and Blue-winged Olive hatches from spring into fall.
