Tennessee Hatch Calendar — Quick Reference
Identifying the hatch is vital, but most days require versatile patterns that trigger strikes even when the water looks quiet. For a curated list of high-percentage patterns that belong in your box year-round, see our guide to the best trout flies in Tennessee, featuring our top 5 essential picks for these waters.
Tennessee Streams
South Holston · Clinch · Hiwassee · Watauga
Cold dam releases from Holston, Norris, Apalachia, and Watauga reservoirs create year-round trout habitat with consistent temperatures. Midge and BWO hatches fire even in January. The South Holston is famous for its dense summer Sulphur hatches, while the Clinch delivers a legendary August Trico spinner fall. These tailwaters are the most technical and most rewarding dry fly fishing in the South.
Little River · Abrams Creek · Tellico River
Wild brook and rainbow trout in a stunning national park setting. These freestone streams track air temperatures closely — best fishing runs April through October. Quill Gordons kick off spring, followed by Yellow Sallies, Light Cahills, and summer terrestrials. Abrams Creek holds wild brook trout at higher elevations. All park streams are catch-and-release with barbless hooks required.
Nolichucky · Ocoee · Buffalo River
Larger freestone rivers with seasonal hatches tied to air temps and snowmelt. The Nolichucky offers excellent spring hatches including March Browns and early Caddis. The Ocoee is a dynamic river with strong Caddis and Yellow Sally hatches in spring and early summer. The Buffalo in Middle Tennessee provides excellent smallmouth bass fishing and limited trout water in its upper reaches.
The Why Behind the Chart
Ephemerella dorothea
Tennessee's signature tailwater hatch and the reason fly anglers plan pilgrimages to the South Holston. Dense, reliable evening rises from May through August bring large brown and rainbow trout to the surface in gin-clear water. The hatch typically fires around 7pm and intensifies at dusk. Trout become highly selective during dense Sulphur hatches — presentation and fly size matter more than almost anywhere else in the state. Fish the #16–18 Sulphur Sparkle Dun in the film for best results.
Recommended: #16–18 Sulphur Sparkle Dun, Parachute Adams
Chironomidae
The foundation of Tennessee tailwater fishing and the only hatch that never truly stops. On the South Holston, Clinch, Hiwassee, and Watauga rivers, midges hatch throughout the year — making winter fly fishing productive even in the coldest months. The Clinch River below Norris Dam is particularly famous for winter midge hatches with large surface-feeding trout. Fish #22–26 Zebra Midges and Griffith's Gnats on 6X or 7X tippet under an indicator or dead-drifted near surface risers.
Recommended: #22–26 Zebra Midge, Griffith's Gnat, Mercury Midge
Baetis sp.
Tennessee's most versatile hatch — present on tailwaters and mountain streams alike, in spring and fall, and reliably triggered by overcast skies and drizzle. BWOs provide the first meaningful dry fly opportunity of the year on all Tennessee rivers in March and April. Fall brings a second strong window from September through November. On cloudy days when nothing seems to be happening, tie on a #18–22 Sparkle Dun and look for subtle sipping rises in the flat water downstream of riffles.
Recommended: #18–22 Sparkle Dun, RS2 Emerger, CDC Dun
Isoperla sp.
Known locally as the Yellow Sally, this early-season stonefly hatch is one of the most reliable indicators that spring fishing has arrived on Tennessee rivers. It's particularly strong on the Hiwassee, Watauga, and Smoky Mountains streams in April and May. Stoneflies don't emerge in the water column like mayflies — they crawl to shore and hatch on rocks, then return to the water to lay eggs. Focus on adult Yellow Sally dry flies and egg-laying patterns in the afternoon when activity is highest.
Recommended: #14–16 Yellow Sally, Stimulator, Yellow Humpy
Tricorythodes sp.
The Clinch River's legendary summer morning ritual. Trico spinner falls from July through September draw trout to the surface in flat, clear water — with the spinner fall often over by 9am. This is technical fishing at its finest: tiny spent spinners on 6X or 7X tippet, low careful approaches, and individual target fish. The Clinch's Trico hatch is considered one of the finest in the eastern United States, with spinner falls that can last for hours and trout feeding in spring-clear water all morning.
Recommended: #22–26 Trico Spinner, CDC Trico, Black-and-White Parachute
Neophylax sp.
Tennessee's fall caddis hatch extends the dry fly season well into November on all the state's major tailwaters. The Autumn Sedge — also called the October Caddis — emerges in the afternoon on cool fall days, bringing fish to the surface even as temperatures drop. It's a large, orange-bodied caddis (#14) that trout take aggressively, making it one of the more forgiving hatches to fish. Fall BWOs often coincide with Autumn Sedge activity, giving anglers two options for rising fish on good fall days.
Recommended: #14 October Caddis, Elk Hair Caddis, Stimulator
Tennessee is home to some of the finest tailwater trout fisheries in the eastern United States. The South Holston and Clinch Rivers below Holston and Norris dams maintain cold water year-round, supporting prolific midge and Blue-Winged Olive hatches even in the depths of winter — making them among the best cold-weather dry fly fisheries in the South.
The South Holston is particularly famous for its Sulphur hatches from May through August — long, reliable evening rises with massive numbers of trout sipping small Sulphur emergers in flat, gin-clear water. The Trico hatch on the Clinch River in August is equally legendary — spinner falls can last for hours with trout feeding all morning. The Watauga and Hiwassee offer excellent Yellow Sally and Sulphur hatches in spring and early summer.
The wild streams of Great Smoky Mountains National Park — including Little River, Abrams Creek, and Tellico River — fish best from April through October with Quill Gordons, Light Cahills, Yellow Sallies, and terrestrials, producing wild rainbow and brook trout in one of America's most beautiful landscapes. Fall brings Autumn Sedge and BWOs through November on all Tennessee waters. Use FlyFishFinder for dam release schedules and real-time flow data to plan your visits.

The South Holston fishes year-round as a tailwater, but peak dry fly action occurs May through August during the legendary Sulphur hatch. Evening rises from 6–9pm with dense Sulphur emergers bring up large brown and rainbow trout. Midge and BWO fishing is excellent in winter and early spring when other streams are cold.
The Clinch is a midge and BWO tailwater that rewards small fly presentations year-round. Winter through spring: #22–26 Zebra Midge and Griffith's Gnat. Summer: #16–18 Sulphur Parachute for evening hatches. August brings an outstanding Trico spinner fall — use #22–26 Trico Spinners on 6X or 7X tippet in the morning. Fall BWOs on #18–22 Sparkle Duns are reliable through November.
The Smokies streams (Little River, Abrams Creek, Tellico) offer wild native brook and rainbow trout in a spectacular national park setting. They're freestone streams that fish best April through October with traditional dry flies like Elk Hair Caddis, Quill Gordons, and Yellow Sallies. Tailwaters like the South Holston and Clinch fish year-round but require more technical presentations to selective trout.
Sulphur hatches run May through August on the South Holston, Clinch, Hiwassee, and Watauga rivers, with peak activity in June and July. The South Holston is particularly famous for dense, reliable evening Sulphur hatches — fish the #16–18 Sulphur Sparkle Dun or Parachute during the 7–9pm window for the best results.
The Hiwassee is a classic Tennessee tailwater with excellent Midge and BWO action in early spring. April and May bring Little Black Caddis and Yellow Sally hatches. Sulphurs peak in June. Summer offers Trico spinner falls and terrestrial fishing. October brings Autumn Sedge action. A well-rounded box includes Zebra Midges, Elk Hair Caddis, Yellow Sally (#14–16), Sulphur Parachute, and an October Caddis pattern.
Yes — GSMNP has hundreds of miles of public trout water open to fly fishing, including Little River, Abrams Creek, and Tellico River. A Tennessee fishing license is required, and all streams in the park are catch-and-release for wild trout. The park streams support native brook trout at higher elevations and wild rainbow trout throughout. Best fishing is April through October, with summer terrestrial fishing being especially productive.
