S8, Ep 55: Summer Secrets: George Costa's Central PA Fishing Report

Episode Overview

In this Central PA Fishing Report on The Articulate Fly fly fishing podcast, host Marvin Cash checks in with George Costa of TCO Fly Shop in State College, Pennsylvania, for an end-of-July conditions update. Costa reports Central Pennsylvania's trout streams running a touch above seasonal averages after a recent shot of rain, with solid dry fly and terrestrial action across the region.

Water levels are in good shape for late summer, and while overnight temps have cooled into the 50s, Costa reminds anglers to keep checking midday stream temperatures on the region's bigger waters, where readings can still creep into the high 60s. On the bug front, Tricos are producing strong morning dry fly action on Spring Creek, with the prime window running roughly 8 a.m. to noon. Terrestrials are working well everywhere, with beetles and ants producing across the board and the season's first hoppers now showing up in the more meadowy stream stretches. Fish are readily eating Chubbies and small hoppers, and dry-dropper rigs — a Chubby up top with a nymph dropper underneath — are working well. For anglers looking to move bigger fish, Costa points to streamer fishing in low light, early and late, as water temperatures cool.

Beyond the stream report, Costa previews TCO's Outdoor Fly Fishing Festival at the shop's Boiling Springs location on Children's Lake, coming up August 8th and 9th, and recaps a strong showing at the shop's recent Bass Thumb smallmouth tournament, which saw high, dirty water but plenty of big fish caught.

Key Takeaways

• How to time the Trico hatch on Spring Creek for peak morning dry fly action, roughly 8 a.m. to noon.
• Why terrestrial patterns like beetles and ants are producing well everywhere right now, with the season's first hoppers now showing up in meadowy stream stretches.
• When to switch to streamer fishing for a better shot at moving bigger fish, ideally during low light in the early morning or evening.
• Why checking midday water temperatures still matters on bigger Central PA streams even when overall levels and clarity are favorable.
• When to plan a visit to TCO's Outdoor Fly Fishing Festival in Boiling Springs, running August 8th and 9th at Children's Lake.

Techniques & Gear Covered

Costa's report centers on a classic late-July technique mix for Central Pennsylvania's trout streams: morning Trico dry fly fishing, terrestrial presentations through the day and streamer fishing during low light. Beetles and ants are producing well across the board, while the season's first hoppers are emerging specifically in meadowy stream stretches. Dry-dropper rigs — running a Chubby as the top fly with a nymph dropper underneath — are producing consistent results. For low-light streamer fishing, Costa notes that slightly cooler water temperatures in the early morning and evening make fish more willing to chase.

Locations & Species

This report covers Central Pennsylvania's trout streams generally, with Spring Creek specifically called out as producing strong morning Trico activity. Wild and stocked trout are the primary target throughout the region. Seasonally, this is a slightly atypical late-July window: stream levels running a little above seasonal averages and on the clear side following recent rain, overnight temperatures in the 50s, and daytime highs in the mid-70s to low 80s making midday water temperatures a point of attention on the region's bigger streams.

FAQ / Key Questions AnsweredWhat are current stream conditions in Central PA in late July?

Costa reports levels running a little above seasonal averages and on the clear side following a recent rain event. Overnight temperatures have been in the 50s with daytime highs in the mid-70s to low 80s, keeping overall stream temperatures favorable, though bigger streams can still creep into the high 60s by midday.

When is the best time to fish Tricos on Spring Creek?

Costa identifies roughly 8 a.m. to noon as the prime window for Trico dry fly action on Spring Creek, when hatch activity is strongest.

What terrestrial patterns are working best right now in Central PA?

Beetles and ants are producing well everywhere, and the season's first hoppers are starting to show up specifically in meadowy stream stretches. Costa notes fish are readily eating Chubbies and small hoppers, and dry-dropper rigs — a Chubby up top with a nymph dropper underneath — are working well.

When should anglers switch to streamer fishing during summer trout season?

Costa recommends streamer fishing during low light, early morning or evening, when slightly cooler water temperatures tend to make trout more willing to chase a moving fly.

What TCO Fly Shop events are coming up this August?

TCO's Outdoor Fly Fishing Festival takes place August 8th and 9th at the shop's Boiling Springs location on Children's Lake. Costa also recapped a strong turnout at the shop's recent Bass Thumb smallmouth tournament, where high, dirty water didn't stop anglers from catching some larger fish.
