What the gauge above the powerhouse actually measures
USGS 02181580 sits between Tallulah Falls Dam and the Georgia Power powerhouse at the bottom of the gorge, below a low-head dam that American Whitewater notes right above it. That puts it on the two-mile bypassed reach through Tallulah Gorge, so it reads the water Georgia Power lets fall over the dam, not the river that goes through the penstock to the turbines. From September 2 to September 23, 2026 it read 37 to 40 cfs on every ordinary day, spiked to 108 on one afternoon of rain, and never touched the releases, because there were none in that window. The Clayton gauge, 02178400, is a different river entirely, the freestone above Lake Burton, and it read 62 cfs the same evening.
Aesthetic 200s and whitewater 500s: the release calendar
Tallulah Gorge State Park describes the flow in the gorge as 35 to 40 cfs on a typical day, 200 cfs during aesthetic releases and 500 cfs on the Saturday and 700 cfs on the Sunday of whitewater weekends. The whitewater weekends are fixed: the first two weekends in April and the first three in November, when boaters carry down 592 stairs to run a mile and a third of class IV and V into Lake Tugaloo. Aesthetic releases run 8 a.m. to 8 p.m. on scheduled weekends in spring and again around Labor Day; the 2026 dates the town and park posted include May 9 and 10, May 16 and 17 and September 5 and 6, and the park's page at 706-754-7981 is where to confirm the rest. On this page, a reading near 40 is the base, 200 is an aesthetic day and 500 or more means the kayakers have the gorge.
One hundred gorge-floor permits, none on release days
Fishing the gorge floor means a free permit from the Interpretive Center, limited to 100 a day, issued first come in the morning and not after 4 p.m., or 3 p.m. during daylight saving time. They are not issued at all during water releases. The fishery down there is largemouth and redeye bass in the plunge pools at the base flow and whatever holds in Tugaloo's backwater; it is not a trout river below the dam. The state's trout-water list makes that explicit: in Rabun County every unlisted stream is trout water except the Tallulah River downstream from Lake Burton Dam, the Chattooga below Warwoman Creek and the tributaries to the Burton, Seed, Rabun, Tallulah Falls, Tugaloo and Yonah reservoirs, so from Burton Dam down through the gorge the general fishing rules apply and no trout license is needed.
The other Tallulah: Tate City, Tate Branch and Sandy Bottoms
The trout river is 30 miles upstream. From Clayton take U.S. 76 west eight miles, turn north on Persimmon Road for five, then left on Tallulah River Road, Forest Service Road 70, which follows the river past three Forest Service campgrounds, Tallulah River, Tate Branch and Sandy Bottoms, through Tate City and on to the Southern Nantahala Wilderness at the North Carolina line. DNR calls it a very popular river stocked frequently from mid-March to early September because of the pressure, and the 2026 stocking table puts both the Rabun and Towns County sections in the top tier: weekly from April through July 31, twice before Labor Day and once in September or October, with nine- to eleven-inch rainbows. The Coleman River comes in just above the Tallulah River campground through a 330-acre scenic area of old-growth timber, and from that junction up to Forest Service bridge 54 it and its tributaries are artificial lures only, with bait possession illegal; it is the place to find wild fish when the stocked water is crowded.
Eight trout, no size, all year, and a trout license
Above Lake Burton the regulations are Georgia's standard trout set: eight brook, rainbow or brown trout a day in any combination, no size limit, open year-round since the state ended seasonal streams, one handheld pole and line, no live fish for bait, and a trout license with the fishing license for anyone 16 or older. Lake Burton itself is stocked once a year. Reeves Ace Hardware and its Outdoor Center on South Main Street in Clayton is the local shop; Unicoi Outfitters in Sautee and Clarkesville publishes the weekly north Georgia report and hatch notes; the Chattooga River Fly Shop on SC 28 at Mountain Rest is the nearest full fly shop to the headwaters.
A north Georgia freestone calendar
No one publishes a chart for the Tallulah alone. Unicoi's spring reports name the Rage Cage caddis, March Brown, parachute Adams and olive dries for the Rabun County streams, and Bowman's north Georgia freestone chart, written for the Etowah headwaters 50 miles west, puts black stoneflies and midges in February and March, Quill Gordons, Hendricksons, Blue Quills and Grannoms in April, Sulphurs and March Browns in May, Light Cahills and Yellow Sallies in June, terrestrials through August and Tricos in September. The stocked rainbows in the campground water eat whatever is drifting; the wild fish up the Coleman are the ones that make the calendar matter.
