About the Susquehanna

The Susquehanna is the longest river on the East Coast. It starts in Cooperstown, New York, and runs about 774 miles to the Chesapeake Bay. In Pennsylvania it is wide, shallow and full of rocky riffles and long runs. That makes it prime smallmouth habitat.

Smallmouth bass are the main draw, and the river also holds rock bass, bluegill, crappie, yellow perch, walleye, northern pike, muskellunge, common carp, channel catfish and fallfish. Harrisburg has some of the best known smallmouth water in the state. Sidney offers good wading spots on the New York side.

Most fly anglers float the river from Sunbury down toward Harrisburg. Wade anglers have plenty of public access, but the river can be dangerous at high water. A boat access like Fort Hunter helps, though wading is not an option at some ramps.

Spring is the season in our records. Water temperature and flow shape the bite more than anything. Crawfish patterns and Dungeons are classics. Check the current Pennsylvania Fish and Boat Commission regulations for the section you plan to fish.

Tips for fishing the Susquehanna

  • Watch the river level

    The Harrisburg gage is the number most local anglers watch. High water makes wading dangerous.

  • Float from Sunbury

    Longer floats between Sunbury and Harrisburg cover a lot of smallmouth water.

  • Fish crayfish patterns

    Smallmouth eat crayfish all year. A crawfish pattern is a safe starting point.

  • Wade with a buddy

    The river is wide and the current can be strong. Wear a wading belt.

  • Use the app for access

    The FlyFishFinder app maps public access points and live gages along the Susquehanna so you can plan a float.
