What the Genesee River offers and where to fish it

The Genesee River runs 144 miles from the Pennsylvania border north through western New York to Lake Ontario, and it holds smallmouth bass, walleye, channel catfish, and carp year-round. The river splits into three distinct fishing zones: the upper reaches near Wellsville are fast, rocky, and best for smallmouth in spring and fall; the middle section around Letchworth State Park offers deeper pools and slower current where walleye hold in summer; and the lower river from Mount Morris downstream to the lake is wide, slower, and productive for walleye and catfish in all seasons.

Access varies by section. The upper river has public boat launches at Wellsville and several pull-offs along Route 19. The middle section is trickier—Letchworth State Park allows fishing from shore in designated areas, but launching a boat requires permission and is limited. The lower river has better access: launches at Mount Morris, Geneseo, and several spots near Rochester. Most anglers fish from shore along the lower sections, especially near the dam pools where current concentrates fish.

Key Takeaways

  • Smallmouth bass dominate the upper Genesee from April through June and again in September and October, when water temperatures stay between 55 and 70 degrees.
  • Walleye fishing peaks in the middle and lower river during summer nights and early morning, particularly around current breaks and deeper holes.
  • Channel catfish and carp are active May through October in the lower river, especially near the Rochester area where the river widens.
  • The Genesee is a catch-and-release river for bass in most sections; check current New York regulations for size and possession limits on other species.
  • Water levels rise significantly after heavy rain, making the upper river dangerous and the lower river murky—plan trips around weather forecasts.

Smallmouth bass in the upper river

The upper Genesee from Wellsville to Letchworth is classic smallmouth water: rocky bottom, moderate current, and plenty of structure. Fish hold around boulders, fallen trees, and the inside bends of curves where current slows. Spring (April and May) is the most reliable season—water temperatures climb from the 50s into the 60s, and bass move shallow to feed before spawning. Fish the rocky banks early and late in the day with 4- to 6-inch soft plastics rigged on 1/8-ounce jigheads, or throw small crankbaits that mimic the shiners and dace the river holds.

Fall (September and October) is equally good and often less crowded. Water cools back into the 60s, and bass feed aggressively to prepare for winter. The same techniques work, but focus on slightly deeper water—2 to 6 feet—where bass stage before moving to winter holes. Summer is slow; water warms into the 70s and bass retreat to the deepest pools and shade. If you fish summer, focus on early morning and dusk, and fish the deepest bends and holes you can find.

Access the upper river at the Wellsville boat launch on Route 19 (free, public, small gravel lot) or at several pull-offs between Wellsville and Nunda. Wading is possible in low water, but the current is deceptive—wear a belt and use a wading staff. The upper river is narrow enough that you can cover a lot of water from shore with a spinning rod.

Walleye in the middle and lower sections

Walleye fishing on the Genesee is a night game, especially in summer. The middle river around Letchworth and the lower river from Mount Morris to Rochester hold walleye year-round, but they are most active from May through September when water temperatures stay between 65 and 75 degrees. Fish move to deeper holes and current breaks during the day and move shallow to feed at night. The best approach is to fish from one hour after sunset until midnight, focusing on the outside bends of curves, the tailouts of pools, and anywhere current slows.

Use live shiners or small minnows on a simple slip-sinker rig, or cast small jigs tipped with minnow heads. Fish slowly along the bottom and be patient—walleye bite softly, and you will miss strikes if you set too hard. The lower river near Rochester has several dam pools that concentrate walleye; fish the current seams where fast water meets slow water. Spring (April and May) and fall (September and October) can produce walleye during the day, especially in the deeper pools, but night fishing is still more reliable.

Access the lower river at the Mount Morris boat launch (free, public, adequate parking) or at Geneseo, about 10 miles downstream. Both are suitable for small boats and kayaks. Shore fishing is possible but limited in the lower sections; ask at local bait shops for current access points.

Catfish and carp in the lower river

Channel catfish and carp thrive in the lower Genesee, particularly in the slower, wider sections near Rochester. Catfish are active May through October and will bite during the day, though evening and night produce more consistent results. Fish with chicken liver, cut shad, or commercial catfish bait on a simple three-way rig or slip-sinker setup. Carp are present year-round but feed most actively in spring (April and May) and fall (September and October) when water temperatures are moderate. Fish for carp with corn, dough balls, or specialized carp baits, and use a rod with a sensitive tip so you can detect the subtle takes.

The lower river is wide and slow enough that you can fish from shore in many places, particularly near the Rochester area where public access is more common. Catfish and carp both prefer deeper water and slower current, so focus on holes and bends rather than fast runs. Both species are strong fighters and require heavier tackle than bass or walleye—bring a medium-heavy rod and 12- to 20-pound line.

Seasonal patterns and water conditions

Spring (April and May) is the most productive season overall. Water temperatures climb from the 40s into the 60s, and all species feed aggressively. Smallmouth are shallow and active; walleye move into the shallows at night; catfish and carp begin feeding after winter. The downside is that spring rain raises water levels, which can make the upper river dangerous and turn the lower river muddy. Check the USGS Genesee River gauge at Rochester before you go; flows above 3,000 cubic feet per second make the upper river unsafe for wading.

Summer (June through August) is slow for most species except walleye, which bite well at night. Water warms into the 70s and 80s, and smallmouth and bass retreat to deep holes. Catfish and carp remain active but are less predictable. Fall (September and October) rivals spring in productivity. Water cools back into the 50s and 60s, and all species feed heavily to prepare for winter. Flows are usually stable, and the weather is more pleasant than spring.

Winter (November through March) is difficult. Water temperatures drop into the 30s and 40s, and fish move to the deepest holes and move very little. Some walleye fishing is possible in the lower river, but success is inconsistent. The upper river is often too cold and fast to fish safely.

Regulations and what you need to know

New York requires a fishing license for anyone 16 and older. You can purchase a one-day license online through the New York Department of Environmental Conservation (DEC) website or at most bait and tackle shops. Smallmouth bass in the Genesee are catch-and-release only in most sections; check the current DEC regulations before you fish, as rules can change. Walleye, catfish, and carp have possession limits that vary by year—the DEC website lists current limits by species and region.

The Genesee is a working river with dams and industrial history. Water quality is generally good in the upper and middle sections but can be poor in the lower river near Rochester after heavy rain. Avoid fishing for 24 to 48 hours after significant rainfall, when sewage overflows are common in the Rochester area. Check local news or the DEC website for water quality alerts.

Frequently Asked Questions

Can I launch a kayak on the Genesee?

Yes, in the lower river. The Mount Morris and Geneseo launches accommodate kayaks, and the water is slow enough for paddling. The upper river is too fast and rocky for kayaks except in very low water. Avoid the middle section around Letchworth unless you have permission from the park.

What is the best time to fish for walleye?

May through September, fishing at night from one hour after sunset until midnight. Fish the deeper pools and current breaks in the lower river. Spring and fall can produce walleye during the day, but night fishing is more reliable year-round.

Is the Genesee safe to wade?

The upper river is wadeable in low water, but the current is strong and the bottom is rocky. Always wear a belt and use a wading staff. Check the USGS gauge before you go; flows above 3,000 cubic feet per second make wading dangerous. The lower river is too deep and slow to wade safely.

Where can I find current water levels?

The USGS maintains a real-time gauge for the Genesee River at Rochester. Search "USGS Genesee River Rochester" to find the current flow and water temperature. Flows above 3,000 cubic feet per second indicate high water and unsafe conditions in the upper river.

Do I need a special permit to fish Letchworth State Park?

No permit is required for shore fishing in designated areas of Letchworth State Park, but boat launching is restricted. Contact the park directly at (585) 493-3600 to ask about current boat access policies.
