Native Southern Appalachian brook trout in the Cohutta Wilderness. Small-stream backcountry fishing — the southernmost native brook trout water in the country.
Hatch timing varies week to week with water temperature and weather. Cross-reference this calendar with Georgia DNR or another local fly shop before planning a trip.

Spring emergence
Bars span the typical emergence window for each hatch on Conasauga River. The peak month is outlined and the current month is shaded gold. Mobile users see a month-card view below — a horizontal timeline at 375px is unreadable.

Tap a species for the full profile — water temp triggers, fly patterns, and which other rivers run this hatch.
Chironomids · Snowflies
Year-round food source — the only consistent option on tailwaters in winter. On cold sunny days look for noses sipping clusters in slow water.
BWO · Olive · Little Olive
Most reliable Eastern hatch. Two emergences — spring (March-April) and fall (September-October). Best on overcast, drizzly days.
QG
Classic Catskill spring hatch. First major mayfly of the year on many freestone streams. Emerges underwater — wet flies often outperform dries.
Red Quill · Dark Hendrickson
First substantial mayfly hatch on most Eastern rivers. Spinner falls in evening can be as productive as the dun emergence.
Apple Caddis · Mother's Day Caddis (East)
First major caddis emergence of the year. Look for clouds of small dark caddis above riffles in late afternoon.
Grey Fox · American March Brown
Sporadic emergence rather than a heavy hatch — but trout key on individual large duns drifting through. Freestone-river specialty.
Pale Watery · Little Yellow May
The most important mayfly hatch on Eastern rivers. Reliable emergence + spinner fall every evening for 4-6 weeks. Match the spinners with rusty-bodied patterns.
Cahill
Pale yellow-cream mayfly. Less intense hatch than Sulphur but reliable across many Eastern rivers in late spring through early summer.
Little Yellow Stone
Common on freestone rivers. Adults flutter back to lay eggs on warm afternoons — trout target the egg-laying females.
Spotted Sedge · Cinnamon Caddis
Workhorse summer caddis. Heavy emergences and egg-laying flights at dusk through summer. Drop a soft hackle on the swing during the evening.
Iso · Mahogany Dun (spinner)
Long-running hatch from June into October. Nymphs are strong swimmers and crawl out of the water to emerge — fish a swung wet fly through riffles.
Hoppers · Ants · Beetles
Not a hatch but the most important summer trout food in many Eastern systems. Fish tight to grassy banks and overhanging trees. Hopper-dropper rigs are deadly July through September.
Fall Caddis · Great Brown Sedge
Large orange-bodied caddis. The big fall food source on cold freestone rivers. Trout eat them all day in October but the egg-laying flight at dusk is the most explosive feeding.

Bield: Fish ties USGS gauge data to hatch triggers and alerts you when Conasauga Riverhits the temperature window for the hatch you're waiting on. Plan trips around peak emergence, not the calendar.
