What Big Spring Creek offers and when to fish it

Big Spring Creek is a limestone spring creek in Cumberland County, Pennsylvania, flowing roughly 12 miles from its source near Newville south to the Conodoguinet Creek. The creek is known for stable water temperatures year-round—typically 50 to 55 degrees Fahrenheit even in summer—because it originates from limestone springs. This cold, clear water supports a wild brown trout population and a put-and-take fishery managed by the Pennsylvania Fish and Boat Commission.

The creek is best fished from April through October. Spring (April and May) brings higher flows and active feeding as water temperatures climb from the 40s into the 50s. Summer (June through August) can be productive early and late in the day when temperatures stay coolest. Fall (September and October) offers excellent conditions as water cools again and trout feed more aggressively. Winter is open but flows are lower and trout are less active.

Big Spring Creek draws both fly fishers and conventional anglers. The upper sections near the source are smaller and more technical, favoring light tackle and small flies. The middle and lower sections widen and deepen, holding larger trout and allowing a wider range of techniques. Access is limited to specific public areas and private land with permission, so knowing where you can fish matters before you go.

Key Takeaways

  • Big Spring Creek holds wild brown trout year-round in cold limestone spring water, with the best fishing from April through October.
  • Public access is restricted to a few specific areas; most of the creek flows through private land, and trespassing is not permitted.
  • The upper creek near Newville is narrow and technical, while the middle and lower sections are wider and hold larger trout.
  • Pennsylvania Fish and Boat Commission stocks the creek with put-and-take trout in spring, supplementing the wild population.
  • A valid Pennsylvania fishing license is required; no special permit is needed for Big Spring Creek specifically.

Public access points and where to fish

Public access to Big Spring Creek is limited. The most reliable public access is at Big Spring State Park, located near Newville in Cumberland County. The park has a small parking area and a short walk to the creek. This is the upper section of the creek, where the water is narrower and flows are lighter. The trout here are smaller on average, but the water is clear and technical, making it a good choice for fly fishers practicing with small nymphs and dry flies.

Another public access point is along Orrstown Road (also called Old Orrstown Road) in the middle section of the creek. A small pull-off allows access to a wider, deeper section that holds larger trout. This area is more forgiving for conventional anglers and those new to the creek. Parking is limited and informal; arrive early on weekends.

The lower section of Big Spring Creek, as it approaches the Conodoguinet, flows through private land. Permission from landowners is required to fish here. Some local fly shops and guides have relationships with landowners and can arrange access; calling ahead to a shop in Newville or Mechanicsburg is worth the effort if you want to explore the lower creek.

Always check current access conditions with the Pennsylvania Fish and Boat Commission or a local fly shop before driving out. Flooding, maintenance, or changes in landowner permission can close areas without notice.

What species live in Big Spring Creek and what to expect

Brown trout are the primary species. The wild population consists mostly of fish in the 8- to 14-inch range, though fish to 18 inches are caught regularly in the deeper middle and lower sections. The Pennsylvania Fish and Boat Commission stocks the creek with put-and-take brown trout in spring (typically March and April), adding larger fish that are catchable for several weeks after stocking.

The creek also holds a small population of brook trout, particularly in the upper sections and in small tributaries. These are typically smaller than the browns and less numerous, but they are present. Rainbow trout are not stocked in Big Spring Creek.

Insect life is abundant because of the stable, cold water and limestone geology. Mayflies (especially Baetis and Ephemerella species), caddisflies, and stoneflies are present throughout the season. Midges hatch year-round, even in winter, making the creek fishable on mild winter days. Aquatic worms and small crustaceans are also part of the trout diet.

Regulations and licensing requirements

A valid Pennsylvania fishing license is required to fish Big Spring Creek. Licenses are sold by the Pennsylvania Fish and Boat Commission and are available online, by phone, or at authorized vendors (bait and tackle shops, sporting goods stores, and some convenience stores). A one-day license costs less than a full-year license if you plan only a single trip.

Big Spring Creek has no special regulations beyond the statewide rules. The general trout season runs from the first Saturday in April through Labor Day for most of Pennsylvania, though Big Spring Creek is open year-round. Creel limits are five trout per day during the regular season. Check the current Pennsylvania Fish and Boat Commission regulations before you fish, as rules can change.

Bait fishing is permitted. Live baitfish (shiners, chubs) and worms are commonly used. Fly fishing and spinning with artificial lures are also allowed. Some anglers practice catch-and-release to preserve the wild population, though it is not required.

Seasons and water conditions

Spring (April and May) is the most popular season. Water temperatures rise from the low 40s into the 50s, and the Pennsylvania Fish and Boat Commission stocks the creek in March and April. Flows are higher due to spring runoff, but the water remains clear. Nymphs and small streamers work well. Expect crowds at the public access points on weekends.

Summer (June through August) requires attention to time of day. Water temperatures peak in the mid-50s Fahrenheit, which is still cold by most standards but warm enough that trout are less active during midday. Fish early (dawn to mid-morning) and late (late afternoon into dusk). Midges and small dry flies work during low-light periods. Flows are lower, making the creek easier to wade.

Fall (September and October) is excellent. Water temperatures drop back into the 50s and low 40s, and trout feed more aggressively. Flows remain moderate. Mayflies and caddisflies are still active. This is a good time for both fly and conventional anglers. Crowds are lighter than in spring.

Winter (November through March) is open but challenging. Water temperatures drop into the 40s and below. Trout are less active, but they do feed on midges and small aquatic worms. Flows are lower and clearer. Winter is best for experienced anglers willing to fish small nymphs and spend time on the water. Mild days after a cold spell can produce good fishing.

Gear and tactics for Big Spring Creek

For fly fishing, a 9-foot rod for 4- to 5-weight line is standard. The upper creek near Big Spring State Park is narrow and requires accurate casting to small pockets; a 4-weight is ideal. The middle and lower sections are wider and can handle a 5-weight. Bring a variety of nymphs: Baetis nymphs (size 16 to 20), Pheasant Tail nymphs, small Hare's Ear nymphs, and midge pupae (size 18 to 22). Dry flies include small Baetis duns (size 18 to 20), Caddis patterns (size 16 to 18), and Griffith's Gnats for midges. Small streamers (size 12 to 16) work in deeper pools, especially in fall.

For conventional spinning, light spinning rods (5 to 6 feet) with 4- to 6-pound test line are appropriate. Small spinners (size 0 to 1), inline spinners, and small spoons work well. Worms under a small split shot or bobber are effective, especially in spring after stocking. Panfish-sized jigs tipped with worms also produce.

Wading is necessary on most of Big Spring Creek. The creek is shallow in many places but has deeper pools. Felt-soled wading boots or wading shoes with good grip are important because the limestone bottom can be slippery. Water temperatures are cold year-round, so neoprene waders are recommended even in summer for comfort and safety.
