What Becharof Lake Offers

Becharof Lake is a 154,000-acre wilderness lake in southwestern Alaska, roughly 200 miles southwest of Anchorage, where rainbow trout and Arctic char are the primary draw. The lake sits within Becharof Lake National Wildlife Refuge, a protected area that limits development and keeps the fishery intact. Access is by floatplane only—there are no roads, no lodges on the water, and no services within miles. This isolation is the point: you get a genuinely remote Alaskan experience with reliable fish populations and minimal pressure from other anglers.

The lake is long and narrow, roughly 35 miles end to end, with numerous tributary streams and a complex shoreline that creates good holding water for both species. Rainbow trout here run 16 to 24 inches on average, with fish to 28 inches possible. Arctic char are smaller, typically 12 to 18 inches, but abundant and aggressive on flies and small spinners. The season is short—mid-June through September—because the lake freezes solid in winter and spring runoff keeps water levels high and turbid through early summer.

Key Takeaways

  • Becharof Lake is accessible only by floatplane, and you must arrange transport through a charter service based in Dillingham or King Salmon before you book your trip.
  • Rainbow trout and Arctic char are present year-round in the lake, but the fishing season runs mid-June through September when water temperatures and access are reliable.
  • The lake lies within a National Wildlife Refuge, so you must follow refuge regulations including a 3-fish daily limit for rainbow trout and a prohibition on motors in certain tributary streams.
  • Camping is permitted on refuge lands, but you must pack out all waste and bring all your own food, fuel, and shelter—no resupply is available on the lake.
  • Weather can change rapidly, and the lake is large enough to generate rough water; plan for wind delays and bring extra food and fuel in case your floatplane pickup is delayed.

Getting There and Floatplane Logistics

Becharof Lake has no road access. Your only option is a floatplane charter from either Dillingham or King Salmon, both of which have commercial airports with jet service from Anchorage. The flight from Dillingham takes roughly 45 minutes to an hour; from King Salmon, about 90 minutes. Expect to pay between $600 and $1,200 per person for a round-trip charter, depending on the operator, the number of passengers, and fuel costs at the time you book.

Charter operators typically require a minimum group size—often four to six people—or will charge a higher per-person rate if you are traveling solo or as a pair. Book your floatplane at least four to six weeks before your intended trip, especially if you are traveling in July or August. Weather delays are common in southwestern Alaska; the charter company will reschedule your pickup if wind or visibility makes landing unsafe, but you need to budget extra food and fuel for a potential extra day or two on the lake.

Bring your floatplane operator's contact information and confirm pickup details the day before your flight. Cell service does not exist at Becharof Lake, so you cannot call to reschedule once you are on the ground. Some anglers carry a satellite messenger device (such as a Garmin InReach) to communicate with the outside world in case of emergency or extended delay.

Fish Species, Seasons, and What to Expect

Rainbow trout are the primary target. They spawn in tributary streams in spring and early summer, then move into the main lake body by mid-June. Peak fishing for rainbows is late June through August, when fish are actively feeding in the shallows and around stream mouths. Fish average 16 to 24 inches; a 28-inch rainbow is a genuine prize but not rare. They respond well to small streamers, nymphs, and dry flies during low-light periods.

Arctic char are present in high numbers and available throughout the season. They are smaller than rainbows—typically 12 to 18 inches—but they hit aggressively and are less selective about fly choice. Char tend to school in deeper water during the day and move to shallows to feed in early morning and evening. They are excellent on small spinners, spoons, and bright flies.

Water temperature is cold year-round. Even in August, the lake rarely exceeds 55 degrees Fahrenheit. Fish are active, but they move slowly and do not chase flies far. Expect to cast close to structure—rocky points, stream mouths, and drop-offs—and to fish slowly. Midges and small mayflies hatch throughout the season; carry a range of sizes from 14 to 20.

Regulations and Refuge Rules

Becharof Lake lies within Becharof Lake National Wildlife Refuge. You do not need a special permit to fish, but you must follow Alaska state fishing regulations plus refuge-specific rules. The daily limit for rainbow trout is 3 fish; for Arctic char, the limit is 10 fish. Possession limits are twice the daily limit. Bait fishing is allowed, but many anglers prefer flies and spinners because they are more effective in the cold, clear water.

Motors are prohibited in all tributary streams and in a designated buffer zone around stream mouths. This protects spawning habitat and keeps the refuge quiet. You can use a motor on the main lake body, but many anglers use oars or drift to avoid fuel weight and noise. Check current refuge regulations before you go; rules can change, and the refuge publishes updates on its website.

Camping is permitted on refuge lands, but you must camp above the high-water line and pack out all waste, including human waste. Burn pans are recommended for food scraps. Do not leave any gear or supplies behind, and do not disturb wildlife or vegetation. Bears are present in the area; store food in bear canisters or hang it well away from your camp.

What to Bring and How to Prepare

Pack as if you are going to be stranded for a week. Your floatplane can be delayed by weather for several days, and there is no resupply on the lake. Bring all your food, fuel for cooking, and any medications you need. A lightweight camp stove (white gas or canister fuel) is essential; driftwood is scarce and often wet. Bring a tent rated for wind and rain, a sleeping bag rated to at least 40 degrees Fahrenheit, and a sleeping pad for insulation from the cold ground.

For fishing, bring a 5- to 7-weight fly rod and a 4- to 6-weight rod if you want to fish for char with lighter gear. Pack a range of streamers (Woolly Buggers, Sculpins, Zonkers) in sizes 2 to 6, nymphs (Hare's Ears, Prince Nymphs) in sizes 12 to 16, and dry flies (Adams, Stimulators, Caddis) in sizes 12 to 18. Bring a spinning rod and small spoons (1/8 to 1/4 ounce) as a backup. Waders, a wading jacket, and a hat are essential; the weather is cool and changeable, and you will spend long hours in the water.

Bring a headlamp, a first-aid kit, sunscreen, and insect repellent. Mosquitoes can be heavy in July and early August. A map and compass (or GPS device with fresh batteries) are wise, though most anglers stay close to camp and the main lake body. Binoculars are useful for spotting fish and wildlife. A satellite communicator is optional but recommended if you are traveling solo or as a pair.

Best Times to Fish and Weather Considerations

Late June through mid-August is the peak season. Water temperatures are warmest (still cold, but fishable), daylight is nearly continuous, and weather is most stable. July is often the most reliable month, with fewer wind delays and consistent fishing. Early June can be excellent if you can get there, but water levels are often high from snowmelt, and the lake may still have ice in protected bays. September is possible but weather deteriorates rapidly, and the first freeze can come without warning.

Weather in southwestern Alaska is unpredictable. Expect wind, rain, and fog. The lake is large enough to generate 2- to 3-foot waves in a moderate wind, making it unsafe for small boats. Plan to fish from shore or from a protected bay when wind is high. Bring extra food and fuel in case your floatplane is delayed; a two- or three-day delay is not uncommon. Dress in layers and bring waterproof outer gear. The sun does not set in June and July, so you can fish around the clock, but the light is low in early morning and late evening, which is often the best time to fish.

Alternatives and Similar Fisheries

If Becharof Lake feels too remote or expensive, consider Lake Clark National Park, which is also in southwestern Alaska and offers similar rainbow trout and char fishing. Lake Clark has more lodge options and slightly easier access, though it is still floatplane-only. The trade-off is that lodges are pricier and the experience is less wild.

Naknek Lake, in the same region, is another option with good rainbow trout fishing and more developed infrastructure. It is closer to King Salmon and has several lodges, making it easier to book a trip with meals and guides included.

If you want to stay in Alaska but prefer road access, the Kenai Peninsula offers excellent rainbow trout and salmon fishing on rivers like the Kenai and Russian, though the experience is busier and less remote. The trade-off is convenience: you can drive there, resupply easily, and fish without the logistics of floatplane travel.

Frequently Asked Questions

Do I need a fishing license to fish Becharof Lake?

Yes, you need a valid Alaska fishing license. You can purchase a non-resident license online through the Alaska Department of Fish and Game website before you travel. A 14-day non-resident license costs roughly $65; an annual license is higher. Licenses are required for anyone 16 and older.

Can I fish Becharof Lake solo, or do I need a group?

You can fish solo, but floatplane charters often require a minimum group size (typically four to six people) or charge a higher per-person rate for small groups. Solo travel is possible but more expensive. Consider joining an organized trip or finding other anglers to share the charter cost.

What is the water temperature, and do I need neoprene waders?

The lake rarely exceeds 55 degrees Fahrenheit even in August. Neoprene waders (3 to 5 millimeters) are strongly recommended. Breathable waders will work if you wear heavy fleece underneath, but neoprene is warmer and more forgiving if you take a dunking in cold water.

How many fish can I keep, and can I keep char and rainbows on the same day?

Yes, the limits are separate: 3 rainbow trout per day and 10 Arctic char per day. You can keep both species on the same day as long as you stay within each limit. Possession limits are twice the daily limit (6 rainbows, 20 char).

What if my floatplane is delayed and I run out of food?

This is why you bring extra food and fuel. A two- to three-day delay is not uncommon. Pack for a week even if you plan to stay only four days. If you truly run out of food, you can catch and eat fish, but this defeats the purpose of the trip. Bring a satellite communicator so you can contact your charter operator if the delay extends beyond a few days.
