Green Lake is a remote fly-in destination with strong populations of rainbow trout and char

Green Lake sits in the Tikchik Lakes system of southwestern Alaska, roughly 150 air miles from Dillingham. The lake holds rainbow trout that run 16 to 24 inches on average, with fish over 28 inches possible in summer months. Arctic char are also present and often easier to catch, especially early and late in the season. The lake is shallow in many areas—depths range from 8 to 30 feet across most of the productive water—which makes it responsive to seasonal changes and weather patterns.

Access is by floatplane only. There are no lodges on Green Lake itself, but several remote lodges operate in the Tikchik system and can arrange drop-offs. Charter flights from Dillingham run roughly 45 minutes to an hour each way. The lake is open to fishing from June through September, with peak conditions typically in July and August when water temperatures stabilize and insect hatches become predictable.

Key Takeaways

  • Green Lake holds rainbow trout averaging 16 to 24 inches and Arctic char that are often more cooperative, especially in June and September.
  • Access requires a floatplane charter from Dillingham; no road access or lodges exist on the lake itself.
  • The fishing season runs June through September, with July and August offering the most stable conditions and heaviest hatches.
  • Alaska fishing licenses and a Nonresident Sportfish Tag are required; check current regulations for daily catch limits and tackle restrictions before you go.
  • Shallow water and clear conditions mean fish can be selective; bring a range of fly sizes and be prepared to sight-cast on calm days.

When to fish Green Lake and what conditions to expect

June is the earliest reliable month, but water is cold and snowmelt can cloud the lake. Fishing is possible but slower than mid-summer. Fish are more aggressive in response to the flush of insects, but visibility is reduced and water temperature hovers in the low 50s Fahrenheit. Many anglers skip June unless they have flexible dates and want to avoid crowds.

July and August are peak season. Water clears, temperatures climb into the upper 50s and low 60s, and mayfly and caddis hatches become consistent. Mornings and evenings are most productive, but overcast days can produce all day. Afternoon winds are common in August, which can make sight-casting difficult but also stir up food and trigger feeding. September offers excellent fishing as water cools again and fish feed heavily before winter, but weather becomes unpredictable and floatplane availability may tighten.

Weather changes fast in southwestern Alaska. Afternoon thunderstorms are common in July and August. Wind can pin you to camp for a day or two, especially in September. Pack layers and waterproof gear regardless of the season. Bring a headnet and insect repellent—mosquitoes are heavy in June and July.

Rainbow trout and Arctic char: what each species wants

Rainbow trout in Green Lake respond well to dry flies during hatches, particularly size 12 to 16 caddis and mayfly patterns. Stimulators and Humpies work when you cannot identify the exact hatch. Subsurface, try small nymphs (size 14 to 18) and streaks in olive, tan, and black. Fish often hold in 12 to 20 feet of water but move shallow to feed during low-light periods. Early morning and the last two hours before dark are most reliable.

Arctic char are less selective and more willing to chase. They respond to larger, flashier patterns—size 10 to 12 streamers in white, chartreuse, and orange. Char often hold slightly deeper than trout and are more active in midday. They are also more abundant in the upper end of the lake and in the inlet streams. If trout are refusing, switching to char can save a slow day.

Sight-casting is possible on calm days, especially in the shallower bays. Polarized sunglasses are essential. Fish in clear water can see your line and leader clearly, so 4X to 5X tippet is standard. Longer leaders (9 to 12 feet) help when fish are spooky.

Getting to Green Lake and arranging transport

Dillingham is the hub for floatplane charters to the Tikchik Lakes. The town has a commercial airport served by regional carriers from Anchorage (roughly 1 hour flight time). Most visitors fly into Anchorage first, then connect to Dillingham on a regional airline such as Ravn Alaska or Grant Aviation. Plan at least one full day for the Anchorage-to-Dillingham leg, including layovers.

Floatplane operators in Dillingham include Tikchik Air and other smaller charter services. A one-way flight to Green Lake typically costs between $400 and $600 per person, depending on group size and fuel prices. Round-trip charters are usually discounted. Confirm availability and weather windows before booking; flights are weather-dependent and may be delayed or rescheduled.

Most anglers book through a lodge or outfitter that arranges the floatplane as part of a package. Standalone charter flights are possible but require coordination with the pilot on pickup dates and times. Bring a satellite communicator or personal locator beacon if you are camping independently; cell service does not exist on the lake.

Regulations, licenses, and what you can keep

Alaska requires a Nonresident Sportfish License and a Nonresident Sportfish Tag for anyone 16 and older who is not an Alaska resident. Licenses are available online through the Alaska Department of Fish and Game website or at sporting goods stores in Dillingham. A 14-day license costs less than a full-year license if you are making a short trip.

Daily bag limits for rainbow trout and Arctic char vary by specific water and change year to year. Green Lake typically allows 3 to 5 trout per day, but confirm the current limit before you leave. Some waters in the Tikchik system are catch-and-release only for certain species. Check the current Alaska Sport Fishing Regulations pamphlet, available free online or at Fish and Game offices.

Tackle restrictions are minimal on Green Lake. Single-hook artificial lures and flies are standard. Bait is not permitted in most Tikchik lakes. Barbed hooks are legal but many anglers use barbless to reduce injury and aid release.

What to pack and how to prepare for remote conditions

Bring a 5-weight to 6-weight fly rod and a reel with at least 150 yards of backing. A second rod is wise in case of breakage. Pack a full range of fly sizes (10 to 18) in both dry and wet patterns. Bring extra tippet material in 3X, 4X, and 5X. A net, forceps, and a small repair kit are essential.

Clothing should include a waterproof jacket, fleece layers, and wool socks. Bring a warm hat and gloves even in July—mornings are cold. Waterproof waders are necessary; the water is cold year-round. Bring polarized sunglasses and a headnet for insects. Sunscreen and lip balm with SPF are important; sun reflection off water is intense.

If camping independently, bring a four-season tent, sleeping bag rated to 20 degrees Fahrenheit, and a camp stove. Water is available from the lake. Bring a water filter or purification tablets. Pack high-calorie food; you will burn energy in cold air and on the water. A satellite communicator is strongly recommended for safety.

Frequently Asked Questions

Can I fish Green Lake without staying at a lodge?

Yes. You can arrange a floatplane drop-off and camp independently, but you must coordinate pickup dates with the pilot and bring all camping gear and food. A satellite communicator is essential because there is no cell service. Most anglers find lodge packages simpler because meals and transport are included.

What is the best month to fish Green Lake?

July and August offer the most stable weather, clearest water, and most consistent hatches. June is possible but colder and cloudier. September has excellent fishing but unpredictable weather and shorter daylight. Choose based on your tolerance for cold and wind.

Do I need a guide to fish Green Lake?

No, but a guide is helpful if you are unfamiliar with fly-fishing or want to learn the lake quickly. Most lodges offer guided and unguided options. Unguided fishing is cheaper and gives you freedom to explore, but you will spend time learning the water.

How much does a trip to Green Lake cost?

Lodge packages typically run $3,000 to $5,000 per person for a week, including floatplane transport, meals, and lodging. Independent camping is cheaper but requires more planning. Floatplane charters alone cost $400 to $600 per person each way.

What if the weather prevents my floatplane from flying?

Weather delays are common in southwestern Alaska. Build extra days into your schedule if possible. Most charter operators will reschedule at no charge if weather is the cause. Confirm cancellation and rescheduling policies before you book.
