DIY Guide to Fly Fishing Slate Run in North-Central Pennsylvania

Pine Creek Valley has a secret. You see, Pine Creek Valley is home to Slate Run, a Class A wild trout stream with over seven miles of crystal clear water to explore.

Located near the southwestern side of Tioga county, Slate Run flows downstream through the northwestern side of Lycoming County.

Slate Run is a freestone stream that is a tributary of Pine Creek.

Deep undercuts, spring seeps, and heavy tree canopy, provide for excellent fly fishing for wild brown and brook trout amidst spectacular scenery. 

Fly fishing in Slate Run in north-central Pennsylvania

Slate Run is approximately seven miles long. The headwaters are around three to eight feet wide, with a good pool to riffle ratio. The headwaters originate from the Francis and Cushman branches, with both branches carrying a small population of wild brook trout and wild brown trout.

You’re more likely to find wild brown trout in the lower section of Slate Run, but a small population of wild brown trout can be found in the upper section too. It’s best to fish for wild brown trout early in the morning or late in the day. 

Once you approach Manor Falls, Slate Run begins to change. The pools get deeper and there are more cliffs. Morris Run and Manor Fork add their water not far below the Francis and Cushman branches.

Situated high above Slate Run is Slate Run Road, which runs along the course of the stream. The lower section of Slate Run, located near Pine Creek, is the most popular place on the stream to fly fish. Nearby is another popular Pennsylvania trout stream, Cedar Run, that is also worth exploring. 

Slate Run can be a challenging location for fly fishermen due to the rugged terrain in Tiadaghton State Forest through which it flows. The stream holds many large pools, riffles, and runs that provide excellent trout habitat. With a large amount of coverage provided by fallen timber, Slate Run can be a bit of a workout to fish but its well worth the effort.

Best Spots to Fish Slate Run

Slate Run has only a few access points near the road. You can access Slate Run by pulling off of Slate Run Road, and following one of the angler-made trails to reach the stream. Be prepared for a bit of a hike up and down steep inclines, as Slate Run is located in rugged mountain terrain.

The lower section of Slate Run is the best place to find wild brown trout. While you won’t require a boat, you should stay out of the water as much as possible. Keep an eye out for rattlesnakes in the warm summer months.

Best Time to Fish Slate Run

You can tackle Slate Run all year round. The best trout fishing would be in mid to late spring, but if you are looking to avoid the crowds, you can take on Slate Run in pre and post season.

Your strategy and findings will change with the seasons. In the winter, it is best to go on a warmer day when the water temperature is in the mid forties.

Winter fly fishing can be dangerous though, given the rugged terrain. Trout tend can be found in the larger pools and slower runs during this time of year. Make sure that you check on the safety of the road conditions before venturing out.

Fly fishing in early spring depends entirely on melting snow and stream flow, but May is likely the best month for results. In April, you will be able to find Little Black Stoneflies, Blue Quills, and Early Brown Stoneflies.

May into early June brings the usual March brown, gray fox, sulphur, and green drakes hatches.

In late summer, low water conditions can make fly fishing difficult. Come fall the scenery is breathtaking and the brown trout are spawning.
