PA Rivers Prime Up for Smallmouth, Catfish, and Walleye as Early Summer Arrives

What's Biting

What's Next

With the new moon on June 15, the next two to three days offer some of the most favorable low-light feeding conditions of the lunar cycle for PA river anglers. New moon phases historically produce stronger feeding windows for walleye and catfish — both species that key heavily on darkness and current. Dawn and dusk windows near current breaks, bridge pilings, and the downstream edges of river islands are worth prioritizing on both the Susquehanna and Allegheny through the weekend.

No USGS gauge data came through in this report cycle, so river stage is unknown heading into the forecast window. If recent rains have elevated flows, expect fish to tuck into slower-water eddies and slack pockets downstream of structure — a useful adjustment on any medium to high-water outing. As flows settle and clarity improves, smallmouth bass should become increasingly approachable on rocky runs and shoals. Tactical Bassin's content on Great Lakes smallmouth highlights swing jigs and soft-plastic swimbaits as effective early-summer weapons in river systems — techniques that translate well to Susquehanna smallmouth holding in moderate current over gravel and cobble bottom.

Bob Jensen at Fishing the Midwest advises working weed edges and current seams as a key early-summer strategy, noting that versatile anglers willing to target structure will consistently outperform those locked into a single technique. On the Susquehanna and Allegheny, this means fishing the transition zones between faster riffle water and deeper slow pools — exactly where bass and walleye stack as summer progresses and baitfish concentrate near backwater vegetation.

For catfish anglers, the stretch from now through early July is typically among the most productive of the year on both rivers. Channel cats and flatheads respond well to nighttime drifts with cut bait and live bait fished in deep holes below dams and at river confluences. Expect peak catfish action in the hours around dusk through the coming days.

PA Sea Grant's upcoming HABs webinar on June 25 is worth bookmarking: water quality on both systems can shift quickly during summer warm spells, and anglers should watch for unusual surface discoloration or foam in slower backwater sections before wading in. If you spot a bloom, move upstream or seek another access point.

Context

Mid-June on the Susquehanna and Allegheny typically represents a clear seasonal turning point. By this date in a normal year, post-spawn smallmouth bass have completed their recovery period and are transitioning away from shallow bedding areas toward summer structure — submerged rock ledges, current seams, and deeper pool margins. Both rivers carry historically strong warmwater populations, with the Susquehanna in particular regarded as one of the premier smallmouth rivers in the eastern United States.

No comparative angler reports surfaced in this cycle that directly address how the 2026 season is tracking on these specific systems relative to prior years. The PA Fish & Boat Commission's biologist reports page was present in the data feed but returned only site navigation — no current field reports were available. That page remains the best public source for in-season PA river comparisons and stocking updates, and anglers planning trips should check it directly.

Fishing the Midwest's seasonal content offers a broader pattern worth applying here: summer river fishing often outperforms lake fishing as warmwater species lock onto predictable current features, and anglers who shift from lake patterns to river structure tend to find more consistent action through the hottest months. That dynamic holds well for both the Susquehanna and Allegheny, where current-oriented species like smallmouth, walleye, and catfish reach peak vulnerability to structure-targeting presentations right about now.

Barring any unusual drought or flood conditions that may have affected river levels this season — information that would require current gauge data to confirm — mid-June conditions appear to be tracking on a typical seasonal schedule for both systems. Should USGS gauge data become available in a future report cycle, we will be able to speak more precisely to whether flows are running above or below seasonal norms and adjust species outlooks accordingly.
