DIY Guide to Fly Fishing Slippery Rock Creek in Northwest Pennsylvania

Slippery Rock Creek is one of the most popular trout stream in northwest Pennsylvania but is dangerous. 

Every year, people lose their lives to its waters. As the name indicates, its rocks are deceptively slippery, and create hazardous currents. 

That said, if you’re careful, the Creek can yield plenty of trout and smallmouth bass to the talented angler.

Be sure to check out the rest of our guide so you can stay safe while enjoying this alluring fishery.

Fly fishing Slippery Rock Creek in northwest Pennsylvania

Slippery Rock Creek is a 50 mile tributary of Connoquenessing Creek in Northwest Pennsylvania. Its source is found in Hilliards in Butler County and joins Connoquenessing in Ellwood City. 

The Creek flows through McConnells Mill State Park. It is fed by many tributaries, with the most notable being Seaton Creek, Blacks Creek, and Hell Run. If you are feeling extra adventurous, Hell Run has Class A Waters with an excellent population of wild brown trout. Access to Hell Run, however, is difficult. It requires following the trails found near the parking area on Shaffer Road or hiking from the bridge on Mountville Road. This is a very strenuous hike, make sure you are in good shape before you attempt it!

Slippery Rock Creek is very popular with paddlers and white water rafting. The Creek is known for early season trout fishing and its smallmouth bass population, with bass here ranging from 9 to 16 inches. 

Slippery Rock has another drawback as an angling location, in addition to the dangerous conditions. The Creek flows through agricultural land, making the water muddy quickly after rains. Keep an eye on weather conditions leading up to your trip, so you can ensure good fishing when you get there.

Best Spots to Fish Slippery Rock Creek

For ease of approach, it is recommended that you use a canoe or kayak, as road access is limited. Good launching areas include the public access points on Studebaker Road and Stoughton Road. You can pull out at the bridge on Old Butler Road near Rose Point Park. 

The Creek widens downstream from the gorge, and is about 80 to 100 feet wide in places. You’ll find warm water species here like smallmouth bass, musky and walleye.

Three areas of the stream are stocked with trout. The 15 mile long section from Slippery Rock Road to the property line of Heinz Camp has one preseason stocking and two inseason stockings. The half-mile long section from Heinz Camp to the area below the State Route 2022 Bridge is Catch and Release Fly-Fishing Only. 

Stream Flow and Current Conditions

Be sure to check the stream conditions before heading out to fish Slippery Rock Creek. The USGS stream gauge near Wurtemburg, PA provides a good indication of current conditions.

The graph below shows the stream flow (discharge) for the past 7-days. If flows are considerably above or below historical norms (yellow triangles on the chart) then fishing conditions ma not be ideal.

Best Time to Fish Slippery Rock Creek

The season for Slippery Rock Creek is standard Pennsylvania trout season. Spring is the best time to visit for trout fishing. By late June, the temperature of the stream is too warm to support trout, and they seek refuge in cooler tributaries. Fishing for smallmouth bass is excellent throughout the summery.

Slippery Rock Creek has a decent aquatic insect population. In the spring, you will find Quill Gordons, Blue-Winged Olives, and Light Cahills. Caddis are more prevalent than mayflies and are a staple food source for trout and bass alike. August supports a prolific White Fly hatch that provides for hot top water action for smallmouth bass.
