S8, Ep 58: Central PA Fishing Report: George Costa's Summer Strategies for Success

Episode OverviewGeorge Costa of TCO Fly Shop returns to The Articulate Fly fly fishing podcast for another Central PA Fishing Report with host Marvin Cash, checking in on mid-summer conditions across the region's limestone streams. It's a mixed picture: recent weekend rain has pushed the Little Juniata River high and essentially unfishable for the next few days, while Spring Creek, Fishing Creek and Penns Creek remain in solid seasonal shape with manageable flows.

Costa reports classic mid-summer fishing, with mornings through late-morning and evenings producing the most consistent action. Tricos are showing sporadically, especially on Spring Creek, alongside a scattering of blue-winged olives and small quills. The terrestrial bite is picking up, with ants and beetles drawing steady interest from trout. Costa's go-to approach right now is a dry-dropper rig: a size 12 or 14 Chubby Chernobyl or beetle pattern up top with a small ant or Greenie Weenie dropped underneath, a setup that pulls fish on both the dry and the nymph.

Beyond the stream report, Costa previews TCO's free Fly Fishing and Outdoor Festival this weekend at the Boiling Springs shop on Children's Lake, plus ongoing summer sale pricing as the shop transitions its inventory toward fall. He also flags a strong smallmouth bass bite on Pennsylvania's bigger rivers, including good topwater action despite elevated flows on the West Branch and the Juniata.

Key TakeawaysHow to fish Central PA limestone streams during mid-summer high-water conditions by targeting Spring Creek, Fishing Creek and Penns Creek while avoiding a blown-out Little JuniataWhen to be on the water for the best mid-summer dry fly action, focusing on first light through 10 or 11 a.m. and again in the eveningWhy a dry-dropper rig combining a size 12 or 14 Chubby Chernobyl or beetle with a small ant or Greenie Weenie dropper is an effective search strategy right nowHow to identify a viable mid-summer smallmouth bass alternative on Pennsylvania's larger rivers when trout water runs highWhen to expect terrestrial patterns like ants and beetles to outperform sparse trico and olive hatches on Central PA streams

Techniques & Gear CoveredCosta's core mid-summer strategy centers on a dry-dropper rig built around a size 12 or 14 Chubby Chernobyl or large beetle pattern as the top fly, with a small ant or Greenie Weenie dropped off the back to cover both surface and subsurface feeders. He notes that most of the action is currently coming on the dropper rather than the top fly, though occasional risers will still take the dry. On the hatch front, sporadic tricos, a handful of blue-winged olives and small quills round out the surface options, while the terrestrial bite on ants and beetles continues to build as summer progresses. For the smallmouth side of the report, Costa points anglers toward topwater presentations on Pennsylvania's bigger rivers as an alternative when trout streams are running high.

Locations & SpeciesThis report centers on Central Pennsylvania's limestone spring creeks, with Spring Creek, Fishing Creek and Penns Creek all holding good seasonal flows and cool enough temperatures to fish through the heart of summer, while the Little Juniata River is running high and unfishable following recent weekend rain. Wild trout are the primary target across these limestone waters, with dry-dropper presentations and terrestrial patterns proving most effective during the current mid-summer conditions. Costa also highlights a secondary smallmouth bass opportunity on Pennsylvania's larger river systems, including the West Branch and the Juniata, where elevated flows haven't stopped a strong topwater bite from producing quality fish.

FAQ / Key Questions AnsweredWhat is the best time of day to fish Central PA limestone streams in mid-summer?Costa recommends targeting first light through roughly 10 or 11 a.m., along with the evening hours, as these windows have consistently produced the best action during the curr
