Episode Overview

In this Pennsylvania Smallmouth Report on The Articulate Fly fly fishing podcast, host Marvin Cash checks in with Captain Brian Shumaker of Susquehanna River Guides for an early summer conditions update on the Susquehanna River system in central Pennsylvania. With late spawners still working through a post-spawn funk and a stretch of volatile weather keeping temperatures yo-yoing between the 70s and the low 90s, Shumaker explains why the region hasn't fully transitioned to topwater mode — and what that means tactically for anglers on the water right now. He walks through his two-rod, split-presentation approach: one angler working poppers toward the banks to prospect for fish looking up while the other fishes streamers, Clouser Minnows and crayfish patterns off the banks for fish holding deeper. If the topside bite isn't producing, both anglers go under and adjust from there. Shumaker flags the appearance of blue damsels as his primary visual cue that the bug bite is imminent — a reliable seasonal indicator that, combined with warming temperatures, signals the topwater game is close to locking in for the summer and early fall. Forage development is tracking normally despite an unusual spring: small baitfish are present in expected numbers and crayfish are progressing on schedule, suggesting the full summer pattern is assembling without disruption. Both Shumaker and Marvin agree that early July is typically when the topwater game solidifies and runs through the end of the season, making late summer and early fall a prime window for anglers looking to get on the Susquehanna with a guide.

Key Takeaways

How to use a two-rod split approach — one angler on topwater and one subsurface — to efficiently read fish mood and adjust during early summer transition conditions on the Susquehanna.
Why the appearance of blue damsels is a reliable biological indicator that sustained topwater smallmouth fishing is imminent, even when temperatures haven't yet fully flipped.
When to expect the topwater game to solidify on Pennsylvania smallmouth rivers, with early July typically marking the turning point for consistent popper fishing through the rest of the season.
How to work bank structure simultaneously from topside and subsurface angles — poppers toward the banks, streamers and crayfish patterns perpendicular off the banks — to cover the full feeding zone.
Why forage tracking matters early in the season, and what normally developing baitfish and crayfish populations signal about the summer bite ahead.

Techniques & Gear Covered

Shumaker's early summer approach centers on a simultaneous split-presentation strategy: one angler works topwater with poppers along the banks while the other fishes streamers, Clouser Minnows and crayfish patterns subsurface off the banks. The pairing functions as a real-time fish mood check — if the topside bite isn't firing, both anglers shift below the surface and dial in from there. Shimmering Minnow patterns are also in the subsurface rotation. Bank structure is the primary focus throughout, with poppers presented tight to cover and streamer or crayfish patterns cast perpendicular to probe fish holding off the bank.

Locations & Species

The episode covers the Susquehanna River system in central Pennsylvania, which forms the backbone of Captain Brian Shumaker's Susquehanna River Guides operation. Smallmouth bass are the sole target species, with the fishery sitting in a transitional early summer window as late spawners finish shaking off post-spawn lethargy and conditions trend toward the full bug-and-topwater season. Temperatures are running below average for the time of year — mornings in the mid-50s, daytime highs in the 70s — with additional rain in the forecast, conditions that have delayed the full topwater transition but kept the subsurface bite productive. Both baitfish and crayfish forage are developing on a normal seasonal schedule, a positive signal that the Susquehanna's mid-summer smallmouth pattern should build on pace.

FAQ / Key Questions AnsweredHow should I approach Pennsylvania smallmouth fishing during the early summer transition before topwater locks in?

Shumaker recommends starting every outing with topwater to test whether fish are looking up, then shifting one or both anglers to subsurface presentations if the topside bite isn't firing. The split-rod approach — one angler on poppers, one on streamers or crayfish patterns — lets you gather mood data on the fish in real time without committing the whole boat to a single presentation.

What does it mean when blue damsels start appearing on Pennsylvania smallmouth rivers?

Blue damselfly activity is one of Shumaker's key biological indicators that the transition to sustained topwater fishing is imminent. Once damsels are showing, anglers can expect the bug-driven bite to ramp up, with the full insect-driven topwater game typically locking in by early July and continuing through the rest of the season.

When is the best time of year to book a guided trip on the Susquehanna for smallmouth bass?

While smallmouth are catchable throughout the warmer months, Shumaker and Marvin agree that late September and early October represent a particularly attractive window — fish are shade-seeking and the sun is brutal through July and August, but angler comfort improves meaningfully as temperatures cool heading into fall. Booking windows currently remain open in late July, August, September and October.

Why is forage development tracking an important check early in the smallmouth season?

An unusual spring can shift the timing of baitfish and crayfish cycles, which in turn affects when smallmouth transition between different feeding behaviors. Shumaker notes that forage on the Susquehanna is running on a normal seasonal progression — neither ahead nor behind — suggesting the full summer bite should build predictably even after a stretch of erratic weather.

How do weather and water temperature swings affect the topwater bite on Pennsylvania smallmouth water?

Cooling fronts that push temperatures back into the 70s after brief spells near 90 are enough to reset fish behavior and delay the sustained topwater bite. Precipitation that clouds the water adds another layer of suppression; under those conditions Shumaker defaults to subsurface presentations and waits for water to clear and temperatures to stabilize before committing heavily to poppers.
