Upper Delaware River in New York

The Upper Delaware River in New York, which refers to the 73.4 mile long stretch of the Delaware River from Hancock to Sparrowbush, isn’t as popular with anglers as the East Branch and West Branch of the River. But fly fishermen who skip this section in favor of the other branches will miss out on catching some of the feistiest rainbow trout found in the United States.

Additionally, the Upper Reaches of the River have seen a significant increase in the amount of large brown trout found there, with some recorded catches measuring above twenty inches in length. It’s safe to say that anglers who venture off the beaten path will be rewarded for their efforts.

About Upper Delaware River

Fly fishing the Upper Delaware River

The Upper Delaware River in New York is designated as a Wild and Scenic River by the National Park Service, and it’s not difficult to understand why. Just a few hours north of New York City, It is surrounded by breathtaking wooded mountains and consists of long pools and gentle riffles. It is also characterized by large boulders and steep drop offs.

Most of the land surrounding the Upper Delaware River is privately owned, so access can be tricky, but public use of the waterway is permitted . Nearby, you’ll find the Zane Gray Museum, which honors the American writer who was an angler himself (although he preferred to go for dolphins and porpoises, as opposed to trout). The river is also popular with wildlife enthusiasts, boaters, and bird watchers, who flock to see the bald eagles in the winter months. While swimming is permitted, the swift flow coupled with the slippery rocks make it a dangerous activity to attempt on the Upper Delaware River.

Further downriver, you can spot smallmouth bass, as well as American Shad. But the River is most famous for its plucky rainbow trout. In the lower and middle sections of the main stem, the rainbow trout are more migratory, and your success there will largely depend on the cold water releases of the West Branch, which change drastically from year to year.

Best Places to Fish the Upper Delaware River

As most of the shoreline is privately owned land, anglers typically tackle the Upper Delaware River by drift boat. There are boat launches available from both the Pennsylvania side of the river and New York. It is possible to wade much of the main stem, but it can be treacherous in certain sections depending on the flow conditions and depth. 

The uppermost section, located near Junction Pool, provides the best fishing. This area is safer to wade than the lower sections, but it is still recommended that you use a drift boat.

Best Time to Fish the Upper Delaware River

The River is open year round for catch and release fishing. The best time to visit the Upper Delaware River in New York is from April to June, as that is when the best hatches occur. The most common hatches you will see during this time are mayflies, caddisflies, and stoneflies.

You can also have success tackling this River in the fall when the resident brown trout get aggressive. In October, Isonychias, along with Blue Winged Olives and white flies, become increasingly important.

In the summer, the trout will migrate to the cool water in the uppermost sections and will likely respond well to terrestrials.
