What the Susquehanna River offers anglers

The Susquehanna River is Pennsylvania's largest river and one of the most productive fisheries in the Northeast. It runs 464 miles from New York through Pennsylvania and into Maryland, but the Pennsylvania stretch—especially the middle section through Lycoming County—holds some of the region's best smallmouth bass, walleye, and American shad. The river's size and current create distinct zones where different species thrive, and knowing which dam pool you're fishing matters more than knowing the whole river.

The Susquehanna is dam-controlled, which means the water level and current change throughout the day based on power generation at Conowingo, Holtwood, and Safe Harbor dams downstream. This creates predictable feeding windows and concentrates fish in specific areas. Unlike a free-flowing river, you can plan your trip around generation schedules and know where to find active fish.

Key Takeaways

  • Smallmouth bass are the most abundant species; they hold around rocky structure and current breaks year-round, with spring and fall offering the most consistent action.
  • The river's dam pools create distinct fishing zones, and water generation schedules determine when fish feed and where they concentrate.
  • American shad run upstream in spring (April through early June), and the lower pools near the dams are the most reliable spots to intercept them.
  • Walleye fishing peaks in fall and winter in the deeper pools, particularly around the dam tailraces where current and depth concentrate them.
  • Public boat launches exist at multiple locations, but water levels and current can change rapidly, so check generation schedules before launching.

Smallmouth bass: the year-round foundation

Smallmouth bass are the backbone of Susquehanna fishing. The river holds a strong population of 12- to 16-inch fish, with plenty of 17- to 20-inch specimens if you fish the right structure and timing. Spring (April through May) and fall (September through October) are peak seasons when water temperatures sit in the 55- to 70-degree range and bass feed aggressively throughout the day.

Target rocky shorelines, current breaks behind islands, and the deeper edges of the main channel. Crayfish patterns work year-round—throw 3- to 4-inch crankbaits in crawdad colors, or work soft plastics along the bottom in 8 to 15 feet of water. In summer, fish early morning and evening when the water warms; in winter, focus on the deeper pools and slower current areas where bass conserve energy.

The middle Susquehanna (Lycoming County area) around Muncy Island and the Shikellamy Dam pool holds consistent numbers. Launch at Muncy Island Park or the Shikellamy State Park boat ramp and fish the rocky banks and current seams. The river is wide here, so a boat gives you access to more productive water, but shore anglers can find success along the public access areas on both banks.

American shad: spring migration and timing

American shad migrate upstream through the Susquehanna each spring, typically from mid-April through early June. They're a seasonal opportunity that draws anglers specifically for the run. Shad are fast, acrobatic, and fight hard on light tackle—a 4- to 5-pound shad on a 6-weight fly rod or ultralight spinning gear is a memorable experience.

The lower pools near the dams are where shad concentrate as they move upstream. Conowingo Dam (in Maryland, just below the Pennsylvania border) is the most famous shad spot, but the Holtwood and Safe Harbor pools also hold migrating fish. Shad respond to small shad darts (1/4 to 1/2 ounce) in white, chartreuse, or silver, or small spoons cast and retrieved quickly. Fly anglers use small shad patterns and bright streamers.

The shad run is weather-dependent; water temperature and flow rates trigger the migration. A warm spell in April can bring fish in quickly, while a cold snap can delay them. Local tackle shops and the Pennsylvania Fish and Boat Commission website post run updates during spring. Plan your trip for mid-May if you're uncertain—that's typically the peak window.

Walleye in fall and winter

Walleye fishing on the Susquehanna is a fall and winter game. The deeper pools and tailraces below the dams hold walleye year-round, but they're most active and concentrated from September through March when water temperatures drop. Walleye prefer low-light conditions, so dawn, dusk, and overcast days are prime time.

Fish the tailrace areas below Holtwood and Safe Harbor dams with live shiners or shad, or work jigs tipped with soft plastics along the bottom in 15 to 30 feet of water. The current and depth in these zones concentrate walleye, and the dam's structure creates feeding opportunities. Night fishing under lights can be productive if you have a boat equipped for it.

Walleye fishing requires patience and precision. You're working specific depth zones and current breaks, not covering water like you would for smallmouth. Bring a fish finder if you have a boat; it cuts the learning curve significantly. Shore anglers can fish the public areas near the dams, but boat access to the deeper pools is more reliable.

Water generation schedules and safety

The Susquehanna's water level changes throughout the day based on power generation at the dams. Generation typically increases during morning and evening peak-demand hours and decreases at night and midday. This affects water depth, current speed, and where fish hold. Check the generation schedule before you fish—it's posted on the PPL (Pennsylvania Power and Light) website and updated daily.

Rising water can push fish into shallower areas and increase feeding activity. Falling water concentrates fish in deeper pools and current breaks. If you're wading or launching a boat, be aware that water can rise quickly and unexpectedly. Never wade in the tailrace areas below dams; the current and sudden releases are dangerous. Stay off the water during heavy generation periods if you're in a small boat.

Check generation schedules at pplweb.com/generation or call the dam operators directly. The Conowingo Dam hotline and Holtwood Dam information line provide real-time updates. Planning your trip around low-generation windows gives you safer, more predictable conditions.

Public boat launches and access

Several public boat launches provide access to the Susquehanna in the Lycoming County area. Muncy Island Park (near Muncy) has a ramp and parking; it's a good starting point for fishing the middle river. Shikellamy State Park (near Sunbury) offers a larger facility with multiple ramps, parking, and amenities. Both are maintained by the Pennsylvania Fish and Boat Commission.

Shore access exists along both banks in public areas, though much of the river is private. Shikellamy State Park has shoreline access, and several public fishing areas are marked along Route 15 and local roads. Ask at local tackle shops for current access points; they change based on landowner permissions and seasonal closures.

Boat rentals are available at some marinas, but they're not common on the middle Susquehanna. Bring your own boat or fish from shore if you don't have one. The river is navigable for small to medium boats, but respect the current and generation schedules.

Tackle and seasonal patterns

Smallmouth fishing calls for medium-power spinning or baitcasting rods with 6- to 10-pound line. Crankbaits, soft plastics, and live crayfish all work. Shad fishing uses ultralight to light tackle—6-pound line on a spinning rod is ideal. Walleye fishing benefits from a 6- to 7-foot medium-power rod with 8- to 10-pound line and a sensitive tip to feel bottom structure.

Spring (April–May) is shad season and good smallmouth fishing. Summer (June–August) is slower for most species due to heat and low water; fish early and late. Fall (September–October) is excellent for smallmouth and the start of walleye season. Winter (November–March) is walleye-focused, with occasional smallmouth in deeper pools.

Local tackle shops in Lycoming County—check Muncy, Williamsport, and Sunbury—stock river-specific lures and can provide current conditions and access information. They're worth a visit before your first trip.

Frequently Asked Questions

Do I need a boat to fish the Susquehanna?

No. Shore access exists at public areas, and you can catch smallmouth and shad from the banks. A boat gives you access to more water and deeper pools, but it's not required. Shikellamy State Park and Muncy Island Park both have shore access.

What's the best time to fish for shad?

Mid-April through early June, with peak activity typically in mid-May. Shad respond to water temperature and flow; warm springs bring them earlier. Check local reports before planning a shad-specific trip.

Can I fish the tailrace below the dams?

You can fish from shore in designated public areas, but do not wade into the tailrace. The current is dangerous and water levels change rapidly during generation. Boat anglers should stay clear of the immediate dam area and respect all posted warnings.

What happens if water generation increases while I'm fishing?

Water level and current rise quickly. If you're wading, move to shore immediately. If you're in a boat, head to deeper water away from the main channel and be prepared to leave the water. Check generation schedules before launching and monitor conditions throughout the day.

Are there walleye in the upper pools?

Walleye are present throughout the river, but they're most concentrated and active in the deeper pools near the dams during fall and winter. The upper pools hold fewer walleye and are better for smallmouth year-round.
