Quick Summary
Penns Creek is in a good fishing window this morning. USGS showed 269 cfs and 2.19 feet at 8:00 AM, and the current local conditions update reported high-50s water with some color. Expect nymphs to keep producing through the day, then look for sulphurs, tan caddis, March Browns, and spinner activity toward evening if the forecast storms stay clear.

Weather
For Coburn, PA, the National Weather Service forecast calls for a high near 86 F with a chance of showers and thunderstorms after 4 PM. Wind should stay light from the west, but any thunderstorm can change light, clarity, and wade safety quickly. Have an exit plan if clouds build over the valley late in the day.
River Notes
The gauge is running below the long-term average but still has enough water for good dry-fly and nymph coverage. The stain is useful on Penns because it gives fish more cover in the lower flow. Start in riffle drop-offs, shaded banks, and slower buckets, then move to flats and tailouts once bugs or spinners show.
Hatch Activity
Current hatch guidance is based on today's public local conditions update, current official gauge/weather data, and seasonal May timing for Penns Creek.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 14-16 | Primary late-day mayfly target |
| Tan Caddis | 14-18 | Carry adults and pupa for riffles and edges |
| March Brown | 8-10 | Larger searching dry or active hatch option |
| Gray Fox | 12-14 | Can mix with March Browns |
| Blue Winged Olive | 18-22 | Useful if clouds or showers arrive |
| Golden Stone | 8-12 | Nymphs are worth fishing in faster lanes |
| Midges | 20-24 | Fallback for selective fish |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur dry | 14-16 | Evening risers and spinner water |
| Dry | March Brown dry | 8-10 | Searching bigger broken water |
| Dry | Tan Caddis | 14-18 | Skate or dead-drift around riffles |
| Nymph | Frenchie | 12-18 | Good searching nymph while waiting for surface activity |
| Nymph | Stonefly nymph | 8-12 | Fish near heavier riffles and ledges |
| Nymph | Zebra Midge | 16-20 | Small dropper when fish get selective |
| Streamer | Sparkle Minnow | 4-10 | Low light or stained banks |
Tactics
Start subsurface in defined lanes and adjust weight until the flies tick bottom without hanging constantly. If sulphurs, caddis, or larger mayflies bring fish up, simplify to one accurate dry or a dry with a small emerger dropper. Near sunset, watch the tailouts and softer glides for spinner falls, but leave the water immediately if thunder is close.
