Floating Alaska's Wild Rivers
These are not managed put-and-take fisheries. They are genuine wilderness rivers running through federal refuge and preserve land, accessible only by floatplane, with wild fish that have never been stocked.
Fishing on our float trips varies by river, season, and species — but the overall approach remains the same: cover water, fish proven techniques, and adapt to conditions daily. Because we float downstream each day, anglers fish genuinely new water constantly rather than returning to the same runs. Many days we fish water that may not see another angler all season.
Alaska Rainbow Adventures has operated float trips on Southwest Alaska rivers since 1993. Our focus is the Kanektok, Alagnak, Togiak, Arolik, and Goodnews Rivers — each a distinct fishery with its own character, its own peak seasons, and its own fish. Our guides adjust techniques daily depending on river conditions, fish behavior, and seasonal patterns, drawing on decades of experience on these specific rivers.
Every one of these rivers offers all five species of Pacific salmon — King (Chinook), Sockeye (Red), Chum (Dog/Keta), Pink (Humpy), and Silver (Coho) — along with resident rainbow trout, Dolly Varden, and Arctic grayling. Most guests fly fish, but conventional tackle is equally welcome and effective depending on species and conditions. These rivers hold wild rainbow trout, Arctic char, Dolly Varden, Arctic grayling, and all five species of Pacific salmon. See our Fly or Spin page for detailed recommendations and our Flies & Tackle page for specific patterns and lures.
We operate under USFWS commercial use permits for the Togiak National Wildlife Refuge (Kanektok, Goodnews, Arolik, Togiak) and NPS permits for Katmai National Preserve (Alagnak, Moraine Creek). Trip dates and group sizes are fixed by permit. Prime dates fill a year or more in advance. Contact us early if a specific river or window matters to you.
The Kanektok River
Our flagship river. A true multi-species system with some of the finest mouse fishing for rainbow trout anywhere in the world — and a season that runs from early Kings in June to Coho silver mania in August.
| Species | Prime Window | Notes |
|---|---|---|
| King Salmon (Chinook) | Mid-June to mid-July | Powerful early-season target. Heavy gear required. |
| Chum Salmon (Dog/Keta) | Mid-June to late August | Prolific throughout. Consistent action on multiple methods. |
| Sockeye Salmon (Red) | Late June through July | Strong fighters. Known for quality as table fare. |
| Pink Salmon (Humpy) | Late July to early August | Even-numbered years only. Can flood the river. |
| Silver Salmon (Coho) | August to early September | “Silver mania” on the Kanektok. Acrobatic topwater action. |
| Rainbow Trout | All season; peak July (mousing) & late Aug (eggs) | Trophy-class fish all season. July mouse fishing is exceptional. Late August trout gorge on salmon eggs. |
| Dolly Varden & Arctic Grayling | All season | Consistent throughout. Grayling on light gear are outstanding. |
Kings: 9–12 wt, sink-tip (Teeny T-400 or SA Wet Tip V) + floating line for shallows.
Chum, Coho, Sockeye + Large Rainbows: 7–9 wt (9 ft 8 wt preferred). 150+ yds 20 lb backing. Floating + sink-tip.
Mouse Fishing: 6–7 wt floating line. Waking mouse patterns in early to mid-July are one of the most exciting presentations on any river we float.
Pinks, Grayling + Small Rainbows: 4–6 wt. Dry flies, nymphs, small streamers.
Egg Patterns & Flesh Flies: Dead-drifted beads and flesh flies become the dominant trout and Dolly trigger when salmon spawn.
General Salmon: Medium-weight, 10–15 lb line, lures 3/8–3/4 oz. Blue Fox Pixies (chrome/red or pink), Mepps spinners, T-spoons.
Kings: Heavy action, 20–30 lb. Large spoons and wobblers.
Grayling, Dollies + Small Rainbows: Ultra-light with small spinners.
All setups: Replace treble hooks with barbless single hooks one to two sizes larger. Required on some waters.
The Alagnak River
A federally designated National Wild and Scenic River with clear water, extensive sandbars, and one of the world’s largest sockeye salmon runs. Trophy rainbow trout with late-August fish reaching exceptional size.
| Species | Prime Window | Notes |
|---|---|---|
| King Salmon | Early July | Kings arrive slightly later here than on Togiak refuge rivers. |
| Sockeye Salmon | Weeks 1–3 of July | One of the world’s largest sockeye runs. Sockeye aggressively pursue streamers in tidewater sections. |
| Chum Salmon | Mid-July through August | Consistent action on the Alagnak’s extensive sand and gravel bars. |
| Pink Salmon | Late July through August (even years) | Can be present in extraordinary numbers on even-numbered years. |
| Silver Salmon (Coho) | August through September | Exciting late-season fishing. Silvers on the Alagnak are aggressive. |
| Rainbow Trout | All season; trophy fish late August | 20–25 inch fish typical late season. Egg patterns and flesh flies behind spawning salmon are the key approach. |
| Dolly Varden & Arctic Grayling | All season | Abundant throughout. Grayling particularly active on dry flies in upper reaches. |
Salmon: 8–9 wt with floating or light sink-tip. The Alagnak’s extensive sandbars make floating lines more versatile here than on most rivers. Sockeye aggressively pursue streamers.
Rainbow Trout: Dry flies, nymphs, egg patterns, flesh flies, egg-sucking leeches, and mouse patterns. Late season, egg patterns behind spawning salmon are the primary approach.
Arctic Grayling: Dry flies in the upper reaches. A 4–5 wt is ideal.
Versatile medium-weight setup covers salmon and trout. Heavy gear for Kings. Lures mimicking salmon eggs, baitfish, and insects are effective depending on timing. Barbless single hooks only.
The Togiak River
Larger and shorter than the Goodnews or Kanektok, the Togiak is a highly productive system that doesn’t receive the attention it deserves. Particularly strong for Coho, Dolly Varden, and trophy rainbows. Limited to four guests and two guides per trip.
| Species | Prime Window | Notes |
|---|---|---|
| King Salmon | June through July | Available earlier than on some other systems. |
| Sockeye Salmon | Early July to mid-August; peak late July | Strong run with consistent numbers through late July. |
| Chum & Pink Salmon | July (Chum); July–Aug (Pink, even years) | Overlapping runs provide continuous salmon action. |
| Silver Salmon (Coho) | August through September | Coho are a highlight of the Togiak. Aggressive and hard-fighting. |
| Rainbow Trout | All season; trophy fish late August | Excellent numbers of resident fish following salmon throughout the season. |
| Dolly Varden & Sea-Run Dolly (Arctic Char) | All season; sea-run fish mid-summer | Both resident and sea-run Dollies present. Sea-run fish are a distinctive feature here. |
| Arctic Grayling | All season | Present throughout, particularly in upper sections. |
Adaptable setups as on the Kanektok and Alagnak — streamers for salmon, egg patterns and flesh flies for trout and char, dry flies for grayling. Given the potential for large fish, robust gear is always the right call on the Togiak.
Spinners and spoons in various sizes for salmon and char. Smaller and lighter lures for trout and grayling. Standard barbless single hook rule applies.
The Arolik River
Celebrated for its gin-clear water and exceptional “Leopard Rainbows” — bold, well-conditioned fish with distinctive markings. A smaller, expedition-style river. We run limited trips annually to protect the fishery.
| Species | Prime Window | Notes |
|---|---|---|
| Leopard Rainbow Trout | All season | The primary draw. Aggressive, well-conditioned fish. Sight-casting in clear water is a frequent option. |
| All Five Pacific Salmon | Seasonal runs similar to Kanektok | All five species run the Arolik, but most guests are here for the trout fishing. |
| Dolly Varden & Arctic Grayling | All season | Good numbers throughout. 4-weight dry fly fishing for grayling in the upper reaches is exceptional. |
Leopard Rainbows: Sight-casting common in clear water. Mouse patterns, leeches, egg patterns during salmon spawns, flesh flies. A 6-weight is a good all-around choice.
Arctic Grayling: 4-weight rod for dry fly fishing in the upper reaches — Humpy patterns, muddlers, smolt imitations.
Silver Salmon (lower river): Floating lines with fast-sinking leaders and weighted marabou leech patterns stripped quickly through the lower 15 miles.
Egg Patterns: Pegged TroutBeads dead-drifted under a strike indicator during salmon spawning periods are highly effective.
Primarily a fly-focused river, but small spinners and spoons mimicking baitfish or eggs are effective for trout and char. Single barbless hooks only.
The Goodnews River
One of the few rivers where landing all five species of Pacific salmon on the fly in a single day is a realistic goal. Chrome Coho arrive continuously from mid-July through mid-September — one of the longest and strongest silver runs we fish.
| Species | Prime Window | Notes |
|---|---|---|
| King Salmon | Late June to mid-July | Clients regularly report Kings over 30 lbs on the Goodnews. |
| Chum & Sockeye Salmon | Early July onward | Thousands of chrome-bright fish arriving from the Bering Sea in early July. |
| Sea-Run Dolly Varden | Mid-July onward | Impressive fish reaching 30 inches. A distinctive feature of the Goodnews. |
| Pink Salmon | Mid-July (even years) | Can flood the river by the thousands on even-numbered years. |
| Silver Salmon (Coho) | Mid-July through mid-September | First Silvers mid-July, chrome fish arriving continuously through mid-September. One of our strongest late-season Coho runs. |
| Rainbow Trout & Dolly Varden | All season; best August | Abundant as fish follow salmon upstream to feed on eggs. August is the sweet spot. |
| Arctic Grayling | All season | Consistently present. Dry fly fishing reliable throughout. |
Kings: 10–12 wt with sinking lines to present large flies effectively.
Chum, Sockeye, Pink, Silver: 7–9 wt. For Silvers, topwater flies and aggressive stripping of streamers can be highly productive — Coho on the surface is a special experience.
Rainbow Trout & Dolly Varden: Egg patterns when salmon spawn. Streamers, nymphs, and mouse patterns also work well.
Arctic Grayling: Dry flies provide consistent action all season.
Salmon: Spinners, spoons, and wobblers in bright colors for chrome fish. Heavier gear for Kings.
Rainbow Trout & Dollies: Smaller spinners and spoons. Egg-imitating lures during spawning periods.
The Goodnews Grand Slam — all five salmon species on fly in one day — is a realistic goal in mid-July.
