Fly Fishing the Chattahoochee River

The most important fly on the Chattahoochee tailwater. Full stop. Midges hatch every month of the year and trout key on them consistently. Size 18–22 in black/silver are the standard. Fish it under an indicator in the seams or dead-drift in the film during active hatches. If you only carry one pattern on this river, carry the zebra midge in three sizes.

Sizes: 18, 20, 22 — Colors: Black/Silver, Red/Silver

The RS2 imitates midge and BWO emergers in the film — the transitional stage where trout are most focused and most vulnerable. When fish are visibly sipping in the surface film but refusing your dry fly, tie on an RS2 and fish it just subsurface. One of the most effective and underused patterns on this water.

Sizes: 20, 22, 24 — Colors: Gray, Olive

BWOs hatch year-round on the tailwater but are most significant in fall and winter when overcast skies trigger afternoon hatches that put fish visibly rising across the river. A size 18–20 parachute pattern in olive/gray is essential. Fish it drag-free in the feeding lanes during the hatch window, typically 1–4pm on overcast days.

Sizes: 18, 20 — Colors: Olive/Gray

Caddis become a significant food source from May through October. The elk hair caddis is the standard attractor dry that covers most situations. Fish it in the riffles and pocket water where caddis concentrate. A size 14–16 in tan or olive covers most Chattahoochee caddis situations.

Sizes: 14, 16 — Colors: Tan, Olive

The most versatile pattern in your box. Fish it as a streamer to cover water and trigger reaction strikes, or dead-drift it like a large nymph through deep pools. Black and olive are the standards. Most effective in low light — early morning, late evening, and overcast days. On the generation schedule, fish a heavy bugger on the drop as water recedes and trout move shallow to feed.

Sizes: 6, 8, 10 — Colors: Black, Olive, Brown

For big brown trout in fall, nothing moves fish like a large articulated streamer stripped aggressively through holding water. Sex dungeons, double bunnies, and similar patterns in black, olive, or white are the go-to options. Target structure — boulders, undercut banks, deep seams — and vary your retrieve until you find the trigger. This is the play when you want the biggest fish in the river.

Sizes: 2, 4 — Colors: Black, Olive, White

Scuds are abundant in the Chattahoochee tailwater and provide a reliable subsurface food source throughout the year. Fish a size 14–16 scud in olive or pink under an indicator through the deeper pools and slower runs. When nothing is actively hatching and fish are holding deep, a scud is often the right call.

Sizes: 14, 16 — Colors: Olive, Pink, Orange

Terrestrials become important on the tailwater from June through September when insects fall from bankside vegetation. A foam beetle or ant pattern fished tight to undercut banks and overhanging trees can produce explosive surface takes on summer afternoons when hatch activity is otherwise slow. Often overlooked, consistently effective.

Sizes: 14, 16 — Colors: Black, Cinnamon

The Quill Gordon is the first significant dry fly hatch of the year on the upper Chattahoochee. It hatches on cool afternoons in March and April, typically when water temperatures reach the mid-50s. Fish a size 14 parachute version in the slower runs and pool tails where trout are rising. This hatch marks the true beginning of spring fishing on the upper river.

Sizes: 14, 16 — Colors: Gray/Brown

The most versatile nymph for the upper river. Imitates a wide range of mayfly nymphs present throughout the year. Fish it on a short leader under an indicator through the deeper runs or high-stick it through pocket water. A size 14–16 covers most situations. Add a bead head version for faster, deeper water.

Sizes: 14, 16, 18 — Colors: Natural Pheasant

Caddis are abundant on the upper Chattahoochee and a size 14–16 elk hair caddis is effective from April through October. Fish it in the riffles and around the rocky pocket water where caddis concentrate. The upper river's wild fish are less selective than tailwater trout and often eat an elk hair caddis with minimal hesitation.

Sizes: 14, 16 — Colors: Tan, Olive

The stimulator is a high-floating attractor dry that imitates stoneflies and large caddis. Extremely effective on the upper river's faster pocket water where fish need to make quick decisions. Fish it in the broken water above and below boulders, through the chutes between ledge rock, and anywhere water is moving quickly. A reliable summer pattern when nothing specific is hatching.

Sizes: 10, 12, 14 — Colors: Orange, Yellow

A heavily weighted attractor nymph that gets down fast in the plunge pools and runs of the upper river. The Copper John is a search pattern — use it when you're covering water rather than matching a specific hatch. Extremely effective as a dropper below a dry fly in the pocket water approach that works well throughout the upper river.

Sizes: 14, 16 — Colors: Red, Green, Natural

Terrestrial patterns are highly effective on the upper river in summer. Grasshoppers, beetles, and ants fall from the streamside vegetation throughout the warm months and trout key on them. Fish terrestrials tight to the banks — within inches of overhanging grass and tree roots — where they fall naturally. The takes are often aggressive and the fishing can be explosive on a good summer afternoon.

Sizes: 10–16 — Colors: Black, Yellow, Tan
