Weekly AI Outlook as of 06/05/26
Flows running at 113 cfs — slightly below normal but still fishable — with water temps hitting the sweet spot at 63.7°F. Yellow Sally stoneflies are peaking right now and trout are eagerly taking dry flies according to Little River Outfitters. Clear skies through Friday before weekend rain freshens streams. Focus on Yellow Sally patterns during midday warming windows when these golden stones are most active.
- Flow: 113 cfs, below the 172 cfs normal but good fishable levels. Weekend rain should freshen flows without blowing out smaller tributaries.
- Hatches: Yellow Sally stoneflies peaking — trout are eager for dry flies. Try Yellow Sally #14, Yellow Stimulator, or Yellow Elk Hair Caddis patterns.
- Water Temp: 63.7°F — ideal for active feeding and surface activity. High elevation streams staying cool while bugs stay active through midday.
- Best Window: Late morning through early afternoon when Yellow Sallies are most active. Focus 11am-3pm for peak dry fly action before evening cooldown.

About this Water
- Freestone
- Best months: Apr–Oct, peak Apr–June and Sept–Oct
The Great Smoky Mountains National Park holds over 700 miles of trout streams — the most extensive wild trout system in the eastern United States. Native southern Appalachian brook trout (specks) hold the highest-elevation headwaters; rainbow and brown trout dominate middle elevations. Little River, Abrams Creek, Hazel Creek, and Deep Creek are the classic Smokies streams. The fishery is wild — no stocking inside park boundaries — and the fish are small but plentiful. Pocket water character throughout demands accurate roll casts and short drifts.
The Smokies hold the largest wild brook trout population in the southern Appalachians — the only place in the southern range where native specks remain widespread, protected by a century of wild-fish-only park management.
January Outlook
January in Great Smoky Mountains National Park is the off-season. Mountain streams are at their coldest. Wild brook trout enter a dormant phase in high-elevation headwaters. Fishing is possible on mild days in lower-elevation streams.
Productive Patterns
- Planning season — lower elevations fishable on mild days
- Midge Nymph
- Small Pheasant Tail
- Hare's Ear
Tips
If you fish the Smokies in January, focus on lower-elevation sections of the Little River below Elkmont and Abrams Creek near the campground. Temperatures below 38°F in upper streams make fish nearly inactive. Midday fishing on sunny days above 45°F can produce.
Water Notes
Low winter flows 30–150 cfs. Water 34–44°F in high-elevation streams. Lower sections fishable on mild days. No license required inside GSMNP.
February Outlook
February remains deep winter in the Smokies. Some years bring early warming trends that can trigger midge activity in lower-elevation streams. The park is uncrowded and beautiful — fishing limited to mild windows and lower sections.
Productive Patterns
- Midge Nymph #20-22
- Small Soft Hackle
- Pheasant Tail Nymph
- Hare's Ear Nymph
Tips
February rewards patience — watch for warming trends. Two to three consecutive days above 45°F will bring fish to life. Little River below Sugarlands Visitor Center and lower Deep Creek are the best February options. Wild brookies in headwaters remain dormant.
Water Notes
30–120 cfs. Water 36–46°F in lower sections. Higher elevation streams near freezing. Pick mild afternoons above 45°F for best results.
March Outlook
March is the transition month in the Smokies. Lower-elevation streams begin warming and early Quill Gordon and BWO hatches appear on mild afternoons. Wild rainbow trout begin feeding more actively. Park roads open and crowds are minimal.
Productive Patterns
- Quill Gordon #14-16
- Blue Winged Olive
- Hare's Ear Nymph
- Soft Hackle Wet
Tips
The first Quill Gordon hatch is one of the most anticipated events in Smoky Mountains fishing. These early-season dries appear when afternoon water temps reach 50°F — usually in lower sections first. Fish Little River between Elkmont and the Townsend Wye for the earliest spring action.
Water Notes
50–300 cfs. Water 42–52°F. Snowmelt possible after cold snaps. Lower sections warming first. Quill Gordon conditions emerging by late March.
April Outlook
Great Smoky Mountains National Park offers exceptional wild brook and rainbow trout fishing in scenic mountain streams. No license required within GSMNP.
Productive Patterns
- Elk Hair Caddis
- Royal Wulff
- Parachute Adams
- Yellow Sally
Tips
The Smokies' mountain streams are best accessed on foot — no motorized access. The Little River and Hazel Creek are the most productive. Wild brook trout in the upper headwaters are a special experience.
Water Notes
Variable 100–500 cfs. Water 46–54°F in April. Clear and cold mountain streams.
May Outlook
Prime time in the Smokies. Caddis and Sulphur hatches produce dry fly action throughout the national park.
Productive Patterns
- Elk Hair Caddis
- Sulphur
- Yellow Sally
- Royal Wulff
Tips
The spring wildflowers and consistent dry fly fishing make May the most popular time. Fish the Deep Creek area for excellent access to productive water.
Water Notes
200–600 cfs. Water 50–58°F. Beautiful spring conditions in the national park.
June Outlook
Early summer on Smokies streams. The elevation keeps water cool and productive when lowland rivers warm.
Productive Patterns
- Elk Hair Caddis
- Yellow Sally
- Parachute Adams
- Stimulator
Tips
The higher elevation streams (above 3,000 feet) stay productive all summer. The Ramsey Prong and other tributary streams hold brook trout throughout.
Water Notes
150–500 cfs. Water 52–60°F. Elevation moderates summer temps.
July Outlook
July in the Smokies means summer crowds and warm valley air — but high-elevation streams remain surprisingly cool. Streams above 3,500 feet stay below 65°F even in the hottest weeks. Terrestrials and caddis produce well in the early morning.
Productive Patterns
- Elk Hair Caddis
- Stimulator
- Yellow Sally
- Beetle
Tips
Fish high — go above 3,000 feet elevation to find cool water in July. The Ramsey Prong, Porters Creek, and upper Middle Prong of the Little River hold brook trout in summer cold. Fish before 10am for best activity. Avoid heavily trafficked areas near Elkmont in summer.
Water Notes
100–300 cfs. Water 54–64°F in mid-elevation streams, 48–56°F above 3,500 feet. High-elevation headwaters remain comfortable all summer.
August Outlook
Peak summer in the Smokies. The national park is at maximum capacity with visitors but remote headwater streams offer solitude and cold water. Wild brook trout above 4,000 feet elevation are a summer treasure.
Productive Patterns
- Elk Hair Caddis
- Stimulator
- Terrestrial (ant, beetle)
- Yellow Sally
Tips
August means hiking to find good fishing. High-elevation streams accessible only by trail — Hazel Creek, Forney Creek, upper Noland Creek — are worth the effort for wild Southern Appalachian brook trout. Fish the first two miles above major trailhead parking for the best solitude.
Water Notes
80–250 cfs. Water 52–62°F at mid-elevations, 46–54°F in high headwaters. Beat summer crowds by going remote.
September Outlook
Excellent fall fishing in the Smokies. Rainbow and brook trout become aggressive before spawning. Fall color is spectacular.
Productive Patterns
- Blue Winged Olive
- Elk Hair Caddis
- Stimulator
- Terrestrial
Tips
September and October are the Smokies' finest months. Large brook trout in spawning colors are spectacular. Fish the headwater streams for the full fall experience.
Water Notes
150–400 cfs. Water 50–58°F. Outstanding fall mountain stream conditions.
October Outlook
October is the Smokies' finest month. Brook trout in full spawning colors, spectacular fall foliage, cool temperatures, and reliable BWO hatches combine for the year's best conditions. The backcountry streams are at their most beautiful.
Productive Patterns
- Blue Winged Olive #18-20
- Elk Hair Caddis
- Mahogany Dun
- Soft Hackle Wet
Tips
Plan an overnight backpacking trip to Hazel Creek or the Appalachian Trail corridor streams in October — a bucket-list experience. Southern Appalachian brook trout in spawning colors are among fly fishing's most beautiful fish. BWO hatches on overcast afternoons produce excellent dry fly fishing.
Water Notes
100–350 cfs. Water 46–56°F. The park's finest fishing month. Wild brook trout spawning colors are spectacular.
November Outlook
November brings the last of the brook trout spawn and the beginning of quiet season in the Smokies. Crowds disappear after the first cold snap and the streams are all yours. Late BWO hatches on mild afternoons.
Productive Patterns
- Blue Winged Olive
- Midge Nymph
- Soft Hackle Wet
- Small Elk Hair Caddis
Tips
November is underrated on Smokies streams. The leaf drop opens the forest and you can see more water and more fish. Rising trout on a mild November afternoon with a BWO hatch and no other anglers in sight — this is what the Smokies are really about.
Water Notes
80–300 cfs. Cooling 42–52°F. Late season but fish are still active on mild days. No license required.
December Outlook
December closes the active fishing season in Great Smoky Mountains National Park. The streams are beautiful in winter but fish activity drops significantly in cold weather. Occasional mild days allow midge nymphing in lower-elevation sections.
Productive Patterns
- Planning season — occasional mild day nymph fishing possible
- Midge Nymph
- Small Pheasant Tail
- Hare's Ear
Tips
December fishing in the Smokies is possible on mild days in lower-elevation sections but generally not productive. Plan next season's trips instead. The park trail system is excellent for winter walks. Spring fishing begins in March.
Water Notes
30–150 cfs. Water 34–44°F. Near-dormant conditions for cold-blooded fish. Park roads to Clingmans Dome close December 1.
