The Hiwassee below the Apalachia Powerhouse is one of the South's big scenic tailwaters — wide, boulder-strewn pocket water running through a wooded gorge inside the Cherokee National Forest near Reliance. What sets it apart is a plumbing quirk: Apalachia Dam doesn't dump into its own riverbed. It runs the whole flow through an 11-mile mountain tunnel to the Apalachia Powerhouse downstream, and the trout water starts there, at Big Bend. So the flow that governs your day isn't a dam gate — it's how many generators are spinning at the powerhouse, which is what the TVA release reading tells you. Cold, stable tailrace temperatures keep the river fishing year-round over stocked rainbows in the 10-12 inch class and wild and holdover browns that push well past that for anyone willing to throw streamers or hunt the Isonychia window. The bug life is the draw — locals call it the most diverse of any Tennessee tailwater, and it's genuine dry-fly country by reputation.

You read this river by the generation schedule. At base flow — no generators, roughly 100-150 CFS — it's a broad, forgiving wade; you can cross in a lot of places and pick apart the pockets, shoals, and seams with dries and light nymph rigs. Bring one generator online (~1,200-1,500 CFS) and it jumps to pushy drift-boat water and gets unsafe to wade in most spots; two generators (~3,000 CFS) is a full float flow. The pulse takes about 2.5-3 hours to travel from the powerhouse down to Reliance, so on a rising day you can chase the low water downstream and buy yourself extra wading time. The Hiwassee also runs the most dependable schedule of any TVA trout tailwater: the classic summer pattern (Memorial Day to Labor Day) is roughly one generator around 10 a.m., a second at 11, held until at least 7 p.m., while spring lake-refill often runs a pulse schedule (one generator on for an hour, off for three) that opens wading almost anywhere. Check it before you commit — TVA lake info at 1-800-238-2264, option 22 for Apalachia.

The signature events are the spring grannom caddis blizzards and the May-into-summer sulphur show — the two hatches people plan trips around — with big swimming Isonychia nymphs, fished like minnows, drawing browns through the summer, and October caddis and small winter BWOs and midges keeping the year-round dry-fly reputation honest. The powerhouse-to-Reliance float (about six miles, a full day) is one of the more popular drift-boat trips in the region. The downside is baked into the name tailwater: a wading plan can evaporate when the generators come on, and summer weekends bring recreational tubers and paddlers on top of the anglers. Reliance itself is barely a wide spot in the road — one country store/fly shop, a couple of outfitters — with Cleveland the nearest real town and Chattanooga about 90 minutes out.

Species

  • Rainbow Trout
    Primary · Year-round; spring · 10-12"

    TWRA stocks the tailwater and rainbows are the backbone of the fishery, mostly in the 10-12 inch class. The delayed-harvest management on the upper reach improves carryover, so better 12-16 inch fish hold through the catch-and-release months. Come to dries in the caddis and sulphur windows, and to light nymph rigs the rest of the year.

  • Brown Trout
    Secondary · Fall; winter streamer · 12-20"+

    Wild and holdover browns, with some genuinely large fish for anyone willing to work for them. Targeted on streamers, big Isonychia nymphs swung and stripped like minnows, and October caddis. Fall is the window as pre-spawn fish move and feed harder. Only 2 browns of the 7-trout creel may be kept in the regular season.

  • Striped Bass
    Seasonal · Mid-Jun-Sep · 15-20 lb (to 30 lb)

    A summer run pushes up from Chickamauga into the lower, warmer reaches. This is 8-weight big-game work on heavy gear, not trout fishing, but it's a real seasonal fishery for anglers who want to swing big flies for fish that can top 20 pounds.

  • Walleye
    Occasional · Late winter-spring ·

    Present and part of what local shops mean by the river's diverse fishery, most active late winter into spring. Not a fly-rod mainstay, but a bonus fish.

Ideal wading flow100150 CFS
Blow-out>3,000 CFS
Ideal water temp4862°F

Spring (grannom caddis blizzards and early sulphurs, with lake-refill pulse schedules opening up great wading) and early summer (sulphurs plus Isonychia) are prime. Fall brings October caddis, fall BWOs, and pre-spawn browns. Winter fishes on midges and small BWOs thanks to stable tailrace temperatures, and Oct 1 through February is the delayed-harvest catch-and-release window with lighter traffic and shad-kill streamer fishing. Everything keys off the generation schedule: base flow (~100-150 CFS, no generation) is prime wading, one generator (~1,200-1,500 CFS) already floats but is too pushy to wade safely, and two generators (~3,000 CFS) is float-only. The pulse takes ~2.5-3 hours to reach Reliance, so on a rising day you can chase low water downstream. Overcast days extend the BWO and sulphur activity.

Sections

3 sections on this river

Lower — U.S. 411 Bridge to Patty Bridge

FloatRainbow Trout

Lower gradient as the river opens toward the valley, and it warms faster than the upper reaches in summer. Primarily a float — put in at the U.S. 411 bridge, take out at Patty Bridge on river-left (about a 6-mile day; Gee Creek to Patty is an alternate). Wade access is thinner here. It fishes best in the cooler months on huge March-through-early-May caddis hatches and drops off in mid-summer heat, but it's also where the summer striped-bass run pushes up from below.

Best for: Early-season caddis for trout and, in summer, the striped-bass run on heavy gear.

Middle — Reliance to U.S. 411 Bridge

Wade & FloatBrown Trout

The easiest wading water on the river — gentler gradient and more even riffle-and-run than the gorge above. Access comes from roadside picnic areas and Taylor's Island, the state-owned ramp at Reliance by the railroad trestle, and a takeout under the U.S. 411 bridge with ample parking. It fishes best April through June on heavy spring caddis and is floatable on one generator (Reliance or Gee Creek down). A beginner-to-intermediate reach and the best bet for wade anglers when the schedule cooperates.

Best for: Wade anglers and early-season caddis for rainbows and browns; a common one-generator float.

Upper — Apalachia Powerhouse to Reliance (Big Bend)

Wade & FloatBrown Trout · Rainbow Trout

The signature Hiwassee reach and the guides' favorite — big, classic pocket water of boulders, ledge shoals, and long riffle-runs in a wooded gorge. Access is the powerhouse boat launch at the top plus roadside wading along River Road and the John Muir Trail, which parallels the river for about three miles past well-known shoals like Fox's Cabin. This is the head of the delayed-harvest, quality-trout water (Big Bend down to the L&N Railroad Bridge) and carries the most consistent bug activity on the river — grannom caddis blizzards, the May sulphur hatch, and summer Isonychia. Wade at base flow (~100-150 CFS); the powerhouse-to-Reliance float (6 miles, a full day) is the marquee drift-boat trip and needs one-to-two generators (~1,500-3,000 CFS). Big water, slick boulders, and generation risk make it an intermediate wade.

Best for: Dry-fly and nymph fishing for stocked rainbows and wild browns — grannom and cream caddis, sulphurs, Isonychia, and October caddis; streamers and big swimming Iso nymphs for the better browns.

Regulations

Current fishing rules and restrictions

The upper Hiwassee is managed as a Delayed-Harvest tailwater. From the Apalachia Powerhouse down to the L&N Railroad Bridge at Reliance, the river fishes catch-and-release, artificial lures only, from October 1 through the last day of February; the regular season runs March 1 through September 30 with a 7-trout daily creel, only 2 of which may be brown trout. A Tennessee fishing license plus a trout stamp are required.

  • Delayed-Harvest reach: Apalachia Powerhouse downstream to the L&N Railroad Bridge at Reliance
  • Catch-and-release, artificial lures only (bait use or possession prohibited) Oct 1 through the last day of February
  • Regular season Mar 1 - Sep 30: 7-trout daily creel, only 2 of which may be brown trout
  • A ~3-mile stretch between Big Bend and the L&N Railroad Bridge is designated quality trout water
  • Tennessee fishing license plus a trout stamp/permit required

Far more consequential to a trip than the creel limit is the generation schedule out of the Apalachia Powerhouse. Base flow (~100-150 CFS, no generators) wades almost anywhere; one generator (~1,200-1,500 CFS) is too pushy to wade safely, and two (~3,000 CFS) is float-only. The pulse takes about 2.5-3 hours to travel down to Reliance, so a rising day lets you chase the low water downstream. Check TVA lake info at 1-800-238-2264, option 22 for Apalachia, before committing. Verify creel, size, and season dates against the current TWRA trout regulations, which are updated annually.

~1.5 hrs from Chattanooga; ~2.5 hrs from Knoxville and Atlanta; Cleveland, TN is the nearest full-service town (~30-40 min)

Fly Shops

Camping & Lodging

Cherokee NF Gee Creek Campground; Reliance Fly & Tackle campsites and bunkhouse on Childers Creek; dispersed National Forest sites and Quinn Springs. Cleveland, TN has full services about 30-40 minutes out.

The powerhouse boat launch sits at the top of the tailwater; roadside wading follows River Road and the John Muir Trail, which parallels the river for about three miles past well-known shoals (Fox's Cabin fishes the sulphur hatch). State-owned ramp at Reliance by the railroad trestle, with a takeout under the U.S. 411 bridge and plenty of parking. Reliance is a tiny river hamlet — one fly shop/country store and a couple of outfitters. The Ocoee (whitewater, some fishing) and the Tellico freestone are minutes away, and several Hiwassee outfitters run them too. Because releases can turn a wade into a float in a couple of hours, always check the generation schedule before you go.

Caney Fork RiverTN

Nashville's trout river — a cold Army Corps bottom-release tailwater running out of Center Hill Dam and, above all, a midge factory. Center Hill is a hydro-peaking dam, and TVA reports its release on the Lake Info feed, so the whole trip revolves around the generation schedule: wade the gravel flats only on zero generation, float through one or two units. When the turbines spin up the river rises several feet in minutes, so check the release before you go and give it a couple hours to drain after they cut water.

Clinch RiverTN

The Clinch below Norris Dam is Tennessee's oldest trout tailwater and, on the right day, the best shot at a genuinely huge brown in the eastern half of the country — this is the river that gave up the 28-pound-12-ounce state record in 1988, and fish in the high-20s still turn up on TWRA electrofishing runs. Day to day it's a technical, gin-clear midge fishery: the anglers who catch the most are drifting a size-18-or-smaller midge larva or pupa on light tippet, with a 14–20-inch protected slot keeping the big browns in the system. Everything keys off the Norris generation schedule — wade the flats around Miller Island and the weir when the turbines are off, and get well clear before a one- or two-unit release turns 13 miles of tailwater into an unwadeable torrent.

Little Pigeon RiverTN

Three rivers under one name on the Tennessee side of the Smokies — the West Prong and Greenbrier (Middle Prong) tumble down out of the national park as wild-trout freestone pocket water with native brook trout up high, then the same water rolls into Gatlinburg's stocked town reach and out to a warm lowland mainstem. Wild specks and a family stocked stream inside fifteen road minutes of each other.

Little RiverTN

The Smokies' signature roadside freestone — the East Prong drops off the high country below Clingmans Dome, runs a boulder-choked gorge of plunge pools and pocket water past Elkmont and the Sinks, and hits the Townsend "Y" before leaving the park. One watershed stacks warm smallmouth and rock bass at the Y, wild rainbows through the gorge, the park's largest wild browns between Metcalf Bottoms and Elkmont, and native Southern Appalachian brook trout in the headwaters and upper prongs. Short-line, tight-quarters fishing on a 3- or 4-weight; April is the peak with overlapping Quill Gordon, Blue Quill, Hendrickson and caddis hatches.

Nolichucky RiverTN

The big freestone that drains the west slope of the Unaka and Bald mountains and punches through the deepest gorge in the Southeast before it spills out at Erwin. Be honest about what the "Chucky" is: first a smallmouth river, second a whitewater river, and only in the cold months and only up top a trout river. From Chestoa and Erwin down it's rock gardens, ledges, and boulder pockets you work with a 6- or 7-weight and Clousers, crawfish patterns, and dawn poppers for river-wide smallmouth, big muskie in the slow lower reaches, and a seasonal put-and-take stocked-rainbow reach near the Erwin hatchery that warms out of trout tolerance by May.

South Holston RiverTN

The "SoHo" is the tailwater that put Tennessee trout on the map — cold, limestone-rich water from the base of South Holston Dam holding one of the densest wild brown trout populations in the East and a year-round sulphur hatch that makes for some of the most technical dry-fly fishing in the country. A single-generator dam and a re-oxygenating weir dam mean everything keys off the TVA generation schedule: wade the flats before the afternoon release, float when the water's up.
