Toccoa Tailwater vs the South Holston: Two Southern Tailwaters Compared

Daniel Bowman Updated November 4, 2026 10 min read

The South Holston has a big reputation among Southern fly anglers, and of the two, the Toccoa is much closer to Atlanta. If you're weighing them, the useful comparison isn't which one is "better." It's how each river is run, what kind of fish it holds because of that, and whether it fits in a day.

This guide puts the two side by side using the Tennessee Wildlife Resources Agency's management plan for the South Holston and Georgia DNR's own description of the Toccoa, checked November 4, 2026. We guide the Toccoa, so the Tennessee side here comes straight from Tennessee's documents. If the Toccoa is the trip you want, our Toccoa page has the floats.

What do the two rivers have in common?

Both are tailwaters: rivers that run cold below a dam because the water comes from deep in a reservoir. That cold water is what lets trout live through Southern summers. Our guide to tailwaters vs freestone streams explains the basic idea.

Both dams are run by the Tennessee Valley Authority, and both rivers rise and fall with power generation. Beyond that, they differ on almost every point a visiting angler cares about.

How long is each river?

Similar. Tennessee's South Holston management plan says the tailwater "extends ~22.5 km (13.7 mi.) from South Holston Dam to Boone Reservoir," with "an average width of 61 m (200 ft.)." The dam was finished in 1951 in Sullivan County, Tennessee.

On our side, the Toccoa is "14 miles of year-round trout water flowing from Blue Ridge Dam." So the two tailwaters are about the same length.

Where do the fish come from?

This is the biggest difference. The South Holston is built around wild brown trout. The Toccoa is a stocked river.

From Tennessee's plan:

• Browns are wild. "No Brown Trout have been stocked in the South Holston tailwater since 2003 because of the excellent wild Brown Trout fishery that has developed."
• Rainbows are stocked as adults. "Currently, 47,000 adult (9-10 inch) Rainbow Trout are stocked annually in the South Holston tailwater (March-September)."
• The goal is a mostly wild fishery. Tennessee's stated aim is "a high-quality, largely self-sustaining trout fishery."

From Georgia DNR's trout page:

• Both species are stocked. "Rainbow and Brown Trout are stocked annually in the Toccoa."
• Why Georgia stocks: DNR points to the state's calcium-poor soils, which make wild trout populations hard to sustain, so it stocks trout to keep catch rates up. On the Toccoa, DNR says "Rainbow and Brown Trout are stocked annually."

In plain terms, Tennessee manages the South Holston to grow wild browns, and Georgia manages the Toccoa to keep catch rates up with hatchery fish.

How big are the fish?

Different sources, different measures, so read these carefully. Georgia DNR says of the Toccoa: "The majority of trout caught will be in the 8 to 12-inch range, but anglers should be ready for a memorable trout over 20 inches."

On our Toccoa floats, we put it this way: "Rainbows average 8-14 inches with some larger. Browns run bigger—12-15 inches is common in the tailwater, with fish up to 26 inches possible."

For the South Holston, Tennessee's plan doesn't give an average size in a form we can quote. It does say a 2003 to 2004 study measured an overwintering brown trout biomass "highest among all Tennessee tailwaters," and that the rules are designed to shift "population structure toward larger fish." We won't put a catch-size number on it that the agency doesn't publish. The plan also cites studies that "documented substantial natural reproduction (particularly by Brown Trout)," which is the reason Tennessee stopped stocking browns.

What rules protect the fish?

The South Holston has its own special rules. The Toccoa tailwater falls under Georgia's general trout rules.

South Holston rules, from Tennessee's plan and the state's trout regulations:

1. A protected slot. "16–22 inch PLR on all trout," meaning fish in that range must be released.
2. A seven-fish limit. "Seven (7) trout creel limit, only one trout may be longer than 22 inches."
3. Spawning closures. Two major spawning areas are "closed to fishing during November-January," which the plan says protects "large Brown Trout during the spawning season."
4. No snagging. "All snagging was banned in 1999."
5. No bait restriction. The plan says rules include "no bait restrictions."

On the Toccoa, the delayed harvest section is a different stretch, above Lake Blue Ridge, not the tailwater. Our guide to the Toccoa's catch-and-release section covers where it is.

How does each dam run the water?

Differently, and that changes how you plan. On the South Holston, Tennessee's plan says "South Holston Dam's turbine is typically pulsed twice daily," and a weir below the dam "maintains a minimum flow of 90 ft3/s (cfs)."

On the Toccoa, the dam has a single generating unit, and the river "changes when TVA runs the dam's single generating unit and the flow rises fast." Our guide to the Toccoa generation schedule explains how to read it.

What that means for an angler:

On our trips, "guides plan the float around the release schedule, so you don't have to."

When is each river at its best?

Different calendars, because of how each is managed.

On the South Holston, from Tennessee's plan:

• Rainbow stocking runs March through September, with 47,000 adult fish a year.
• Two spawning areas close November through January to protect spawning browns.
• The rest of the river stays open under the slot and seven-fish limit.

Tennessee's plan doesn't name peak seasons or hatch timing, so we won't guess at them. If you're planning a South Holston trip, check the current fishing reports and the state's rules before you go.

On the Toccoa:

• Spring (March to May) and fall (October and November) "are peak seasons with consistent hatches and active fish."
• Winter "can be excellent for big browns with less pressure."
• Summer still fishes, because the water coming out of the dam stays cold.

Georgia's trout rules, as published on eRegulations, say "all designated trout waters are now open year round," so the Toccoa has no closed season.

How far is each from Atlanta?

The Toccoa is a day trip; the South Holston is an overnight. We ran each route through OpenStreetMap's public router on November 4, 2026, with no traffic counted:

Real trips with traffic take longer. Our Toccoa launches are "15 to 30 minutes from town depending on the section," and our water is "90 minutes from Atlanta." A South Holston trip from Atlanta means more than 11 hours of round-trip driving.

How do you read the flows on each?

Check before you go, every time. Both rivers change with releases from the dam, and a river that's perfect in the morning can be high by afternoon.

For the South Holston, Tennessee's plan describes the pattern: the turbine is "typically pulsed twice daily," and the weir below the dam holds a minimum flow of 90 cfs.

For the Toccoa, our river conditions page uses these flow bands, in cubic feet per second:

Our guide to reading a river gauge explains how to read the numbers. On a guided float, your guide checks this for you.

How do you get on the water at each?

On the South Holston, Tennessee's plan names the J. Forrest Thomas Access Area "along Rt. 44," which "provides boating access to anglers in the lower portion of the tailwater." Other access points weren't in the documents we read, so plan your own spots before you go. The plan puts the tailwater's average width at about 200 feet over its 13.7 miles.

On the Toccoa, our float launches are 15 to 30 minutes from Blue Ridge, depending on the section, and we send directions before your trip. If you're fishing on your own, check the release schedule before you step into the river.

Should you clean your gear between the two?

Yes. Tennessee's plan identifies the South Holston as a water where the parasite that causes whirling disease has been found. It also says wild-caught trout used as bait from affected waters must stay in the waters where they were caught. The same plan recommends "cleaning waders and fishing gear."

If you fish both rivers on one trip, clean and dry your waders and boots in between. Our guide to felt and rubber wading boots covers how.

What does a day of fishing cost on each?

On your own, the biggest cost of the South Holston is time. On the South Holston, you'll need a Tennessee fishing license and any trout license the state requires, your own gear, and gas and lodging for a drive of more than 11 hours round trip. We didn't look up Tennessee's license rules or prices, so check the state's page before you go.

On the Toccoa, a nonresident's one-day Georgia licenses run $10 for fishing and $10 for trout, per Georgia DNR, and the drive is about 110 minutes each way.

With a guide on the Toccoa, a half-day float is $425 per boat and a full day is $575, with gear included. Split between two anglers in one boat, that's $212.50 or $287.50 each, our arithmetic.

Who fishes the South Holston?

A lot of out-of-state anglers. Tennessee's 2019 creel survey found that "most South Holston tailwater anglers interviewed during 2019 (52%) were from outside Tennessee (primarily North Carolina and Virginia)." The same survey estimated "19,441 trips comprising 116,203 hours of effort."

What should you check before you go to either?

A short list, whichever river you pick:

1. The release schedule for the dam, the day before and the morning of.
2. The license for the state you're fishing: Tennessee's fishing license and any trout license it requires for the South Holston, Georgia fishing and trout licenses for the Toccoa.
3. The calendar: the South Holston's two spawning areas are closed November through January.
4. The rules: on the South Holston, any trout from 16 to 22 inches goes back, and only one of your seven can be longer than 22 inches.
5. Your gear, cleaned and dried if it was in another river that week.

On a guided Toccoa float, your guide handles the first one and supplies the gear for the last.

Who should pick which river?

Pick the South Holston if:

• You want wild brown trout and a river managed to grow larger fish.
• You can make it an overnight or a multi-day trip.
• You fish on your own and are comfortable planning around changing flows.

Pick the Toccoa if:

• You're coming from Atlanta for the day. It's about 110 minutes, versus about 5 hours 44 minutes to Bluff City.
• You want a guided float. Our tailwater drift boat floats are priced per boat, with one or two anglers in it. A half day is $425 and a full day $575, as listed on our rates page.

What is a Toccoa float like?

A day in a drift boat, covering water you couldn't reach on foot. "We run drift boat floats here, covering miles of water and accessing stretches you can't reach on foot."

What's included and what to know:

1. Gear: rods, reels, flies and terminal gear are provided, and no waders are needed in the boat.
2. Boat: floats are priced per boat for one or two anglers. On the Toccoa, "first-timers often prefer floats" over wading. Our drift boat page explains the boat and the day.
3. License: "Georgia fishing license and trout stamp required—purchase online at gooutdoorsgeorgia.com before your trip."
4. Seasons: "Spring (March-May) and fall (October-November) are peak seasons," and "winter can be excellent for big browns with less pressure."
5. Weather: we cancel or reschedule only for dangerous conditions like lightning or flooding.
