Slippery Rock Creek can be divided into several sections, each offering unique fishing experiences. The upper reaches near Hilliards are narrower with faster currents, suitable for wading. As the creek flows through McConnells Mill State Park, it widens and deepens, featuring the Slippery Rock Gorge with its rugged terrain and large boulders. Downstream from the gorge, the creek broadens further, providing ample space for various fishing techniques.

Trout in Slippery Rock Creek feed on a variety of aquatic insects, including mayflies, caddisflies, and midges. Spring hatches of Quill Gordons and Blue-Winged Olives are particularly significant.

Effective fly fishing methods vary by season. In spring, nymphing with patterns like Pheasant Tails and Hare's Ears can be productive for trout. During summer, dry fly fishing with terrestrial patterns such as ants and hoppers appeals to both trout and bass. Streamer fishing with woolly buggers can entice larger fish year-round.
