What You'll Find in Loyalsock Creek

Loyalsock Creek runs 64 miles from its headwaters in Sullivan County down to the Susquehanna River near Montoursville, and it holds three fish that make the trip worth planning: smallmouth bass, walleye, and flathead catfish. The creek splits into two distinct sections—the upper reaches above Forks are fast, rocky, and cold enough for trout in spring, while the lower half from Forks down to the Susquehanna is slower, warmer, and where the walleye and flatheads live year-round. Most anglers fish the lower section, which is also where access is easiest and parking is more reliable.

The creek's character changes with the season. Spring brings high water and strong current, which pushes smallmouth into slack water behind rocks and fallen trees. Summer lows expose gravel bars and create defined pools where walleye hold during the day and hunt at dawn and dusk. Fall is when flathead catfish are most active and most catchable, though they feed year-round. Winter slows everything down, but the lower creek rarely freezes solid, and walleye will bite on live shiners fished near deeper holes.

Key Takeaways

  • The lower Loyalsock from Forks to the Susquehanna holds walleye and flathead catfish; the upper creek above Forks is smaller and better for smallmouth and spring trout.
  • Public access exists at Forks, Loyalsockville, and near the mouth, but parking is limited and some pulloffs are informal—arrive early or fish weekdays.
  • Walleye bite best at dawn and dusk on live shiners or small crankbaits; flatheads hunt at night and respond to live bluegill or shad fished on the bottom.
  • The creek is open year-round for warmwater species, but water levels and current vary sharply with rain and dam releases upstream.
  • No special permit is required beyond a Pennsylvania fishing license; check current regulations for size and creel limits before you fish.

Access Points and Where to Park

The most reliable public access is at Forks, where Route 87 crosses the creek and a small parking area sits on the north side of the road. This is the de facto launch point for most anglers and is where the lower creek really begins to hold walleye. The parking fills on weekends, especially in fall, so arrive by mid-morning or fish on a weekday. From Forks, you can wade or float downstream toward Loyalsockville, a distance of about 8 miles.

Loyalsockville itself has informal pulloffs along Route 87, but parking is tight and not all spots are legal year-round. The area near the old mill is popular with locals and offers good access to a slower, deeper section that holds walleye. If you're floating, Loyalsockville is a common takeout point; a few local landowners allow parking for a small fee, but ask before you leave your vehicle.

The mouth of Loyalsock, where it meets the Susquehanna near Montoursville, has a state-owned access area with a small parking lot and a boat ramp. This is the best option if you want to fish the lowest mile or two of the creek or if you plan to fish the Susquehanna itself. The ramp is free and maintained by the state, though it can be crowded on weekends during walleye season.

Private land borders most of the creek, so do not trespass. Stick to public access points and ask permission if you see a house or barn near the water. Many landowners are friendly to anglers who ask, but assuming access is how access gets closed.

Seasonal Patterns and What to Fish

Spring (March through May) brings high water and cold temperatures. Smallmouth move into the upper creek and feed aggressively on crawfish and small baitfish. Fish rocky runs and behind large boulders where current breaks. Walleye in the lower creek are active but scattered; live shiners fished near the bottom in deeper holes produce best. Water levels drop through late May, and by June the creek settles into summer patterns.

Summer (June through August) is when the lower creek becomes most fishable. Walleye move into defined pools and deeper runs; fish live shiners at dawn and dusk, or throw small crankbaits (2 to 3 inches) along drop-offs and near submerged logs. Flathead catfish are present but less active in the heat; they feed more reliably at night. Smallmouth in the upper creek are still catchable but slower; focus on early morning and late evening. Water levels are low and clear, so use lighter line and smaller lures.

Fall (September through November) is prime time for flathead catfish. They feed aggressively as water cools, and live bluegill or shad fished on the bottom at night will produce fish in the 30- to 50-pound range. Walleye also bite well in fall, especially in October and early November. Smallmouth in the upper creek are active again as water cools. This is the busiest season on the creek, and parking at Forks fills early.

Winter (December through February) slows the bite but does not stop it. Walleye move into the deepest holes and feed during midday when light is strongest. Live shiners fished slowly near the bottom work best. Flatheads are less active but will still eat live bait at night. The upper creek can be difficult to access if snow is heavy, but the lower creek is usually fishable.

Tackle and Techniques for Each Species

Walleye respond to live shiners (3 to 4 inches) fished on a simple slip-sinker rig or a three-way rig with a dropper. Cast near structure—logs, rocks, drop-offs—and work the bait slowly along the bottom. Small crankbaits (2 to 3 inches) in natural colors also work, especially at dawn and dusk. Use 6- to 8-pound monofilament or fluorocarbon; walleye have good eyesight in clear water. Fish the deeper pools and runs, not the shallow flats.

Flathead catfish are night feeders and require live bait. Bluegill, shad, and herring all work; use fish 4 to 6 inches long and fish them on the bottom with a simple sinker rig. Use 20- to 30-pound braided line and a 3/0 to 5/0 circle hook. Fish from dusk through midnight, and be patient—flatheads often take 20 to 30 minutes to eat. Bring a headlamp and a net; these fish are strong and will run into logs.

Smallmouth bass in the upper creek respond to crawfish imitations, small jigs (1/8 to 1/4 ounce), and topwater lures in low light. Fish rocky runs and behind boulders. Use 6- to 8-pound monofilament and cast upstream, letting the current work your lure. Smallmouth in the lower creek are less common but will eat live shiners and small crankbaits.

Water Levels and Current Conditions

Loyalsock Creek is dam-free, so water levels respond directly to rainfall and snowmelt. Heavy rain can raise the creek 2 to 3 feet in a few hours, making it unfishable. Check the USGS stream gauge for Loyalsock near Montoursville before you drive out; the gauge is online and updates every 15 minutes. A level of 3 to 4 feet is ideal for wading and fishing. Below 2.5 feet, the creek is low and clear, which can make walleye spooky. Above 5 feet, current is strong and fishing is difficult.

The creek is coldest in spring and early summer, when snowmelt and groundwater keep temperatures in the 50s. By July, water warms to the mid-60s, and by August it can reach 70 degrees or higher. Flathead catfish prefer warmer water and are most active when the creek is above 65 degrees. Walleye bite year-round but are most aggressive in spring and fall when water is cooler.

Regulations and What You Need

You need a valid Pennsylvania fishing license to fish Loyalsock Creek. A one-day license costs less than a full-year license and is available online or at any sporting goods store. The creek is open year-round for warmwater species (walleye, catfish, smallmouth). Size and creel limits change, so check the current Pennsylvania Fish and Boat Commission regulations before you fish. As of recent years, walleye have a 15-inch minimum and a 6-fish daily limit, but verify this online because limits are adjusted based on population surveys.

The creek is catch-and-release only for trout in the upper section during certain months; check the PFBC website for exact dates and boundaries. Flathead catfish have no size or creel limit in most of Pennsylvania, and anglers are encouraged to keep them because they compete with native species. Always check current rules before you go.

When to Fish and What to Expect

Weekdays are quieter than weekends, especially in fall. If you fish Friday through Sunday from September through November, expect to see other anglers at Forks and Loyalsockville. Early morning (before 7 a.m.) is best for walleye and smallmouth; if you're fishing for flatheads, plan to be on the water at dusk and stay until midnight or later. Summer is slower than spring and fall, but the creek is more comfortable to fish and parking is easier.

Loyalsock Creek is not a trophy fishery, but it is a reliable one. Walleye average 12 to 16 inches, with occasional fish to 20 inches. Flatheads run larger—30 to 50 pounds is common in fall—and a 60-pound fish is possible. Smallmouth in the upper creek average 10 to 14 inches. The lower creek is more crowded and more productive than the upper creek, but both sections have fish and both are worth exploring.

Frequently Asked Questions

Can I float Loyalsock Creek in a kayak or canoe?

Yes, and it's a popular way to fish the lower creek from Forks to Loyalsockville. The current is gentle in summer and fall, and you can fish as you drift or pull over to wade. Bring a small anchor or a rope to hold position in deeper pools. Spring water levels can be fast and dangerous for inexperienced paddlers, so float only when water is below 4 feet.

Are there any outfitters or guides on Loyalsock Creek?

A few local guides fish Loyalsock, but the creek is not as heavily guided as larger rivers. Contact the Lycoming County tourism office or search online for "Loyalsock Creek guide" to find current options. Many anglers fish it on their own because access is straightforward and the creek is not difficult to learn.

What's the difference between the upper and lower creek?

The upper creek above Forks is smaller, faster, and colder; it holds smallmouth and trout. The lower creek from Forks to the Susquehanna is slower, warmer, and holds walleye and flathead catfish. Most anglers fish the lower creek because it's more accessible and holds larger fish, but the upper creek is worth exploring if you want smallmouth and a quieter experience.

Do I need a boat to fish Loyalsock Creek?

No. You can wade most of the lower creek in summer and fall, and wading is often more productive than floating because you can cover more ground and fish specific spots thoroughly. A kayak or canoe is helpful if you want to cover distance, but not required.

What's the best time of year to catch flathead catfish?

Fall (September through November) is best, when water cools and flatheads feed aggressively. They're catchable year-round, but summer heat makes them sluggish and winter cold slows their feeding. Fish at night with live bait, and expect to catch fish in the 30- to 50-pound range during fall.
