What Lake McDonald offers anglers

Lake McDonald sits in the Tongass National Forest near Hyder, Alaska, and holds cutthroat trout and Dolly Varden in cold, glacial water. The lake runs roughly three miles long and sits at about 200 feet elevation, making it accessible during the short Southeast Alaska summer. Water clarity varies with glacial melt — milky and gray during peak runoff in June and July, clearer by August and September when the streams feeding it settle.

The fishery here is modest compared to Southeast's famous salmon rivers, but that modesty is part of the draw. You will encounter fewer anglers than you would on the Unuk or Salmon rivers near Hyder, and the cutthroat and Dolly Varden respond to small flies and spinners without the crowds. The lake sits in bear country, so preparation and awareness matter as much as tackle.

Key Takeaways

  • Lake McDonald holds cutthroat trout and Dolly Varden in glacial water that clears from August onward, making late summer and early fall the most productive seasons.
  • Access is by foot from the Hyder area or by floatplane, and no developed boat launch exists, so you need either a packraft or floatplane charter to fish effectively.
  • The lake sits in active bear habitat, so you must carry bear spray, make noise while moving, and store food and garbage in bear-resistant containers or hang them properly.
  • Cutthroat and Dolly Varden respond to small dry flies, nymphs, and spinners in the 1/8- to 1/4-ounce range, with best results near inlet streams and drop-offs.
  • Fishing season runs roughly June through September, with clearer water and more stable conditions from August onward.

Getting to Lake McDonald

The most practical route is a floatplane charter from Ketchikan or Juneau. Several operators in Southeast Alaska run charters to remote lakes, and Lake McDonald is a known destination. A round-trip charter typically takes three to four hours total (including flight time and drop-off), and you can arrange a pickup for the same day or camp overnight and return the next day. Floatplane operators know the lake and can advise on current conditions and bear activity.

If you want to hike in, the approach is longer and less direct. From Hyder, trails lead into the Tongass, but Lake McDonald is not on a maintained trail system. Hiking distance and route-finding difficulty depend on which approach you take, and conditions change seasonally. Most anglers who hike in do so as part of a longer backcountry trip rather than a day outing. Talk to the Hyder ranger district or local outfitters about current trail conditions and water crossings before committing to a hiking approach.

Tackle and technique for cutthroat and Dolly Varden

Both species in Lake McDonald are small to medium — cutthroat typically 8 to 14 inches, Dolly Varden 6 to 12 inches — so light tackle works well and matches the forage they eat. A 4- to 6-weight fly rod with a floating line covers most situations. Cutthroat respond to small dry flies (size 14 to 18) during evening rises, and nymphs (size 12 to 16) work throughout the day near structure. Dolly Varden are more aggressive and will chase small streamers and spinners.

Spinners in 1/8- to 1/4-ounce sizes cast well from shore and cover water quickly if you do not have a boat. Fish them along drop-offs and near the inlet streams where the water is cooler and food concentrates. Early morning and evening produce better than midday, especially in clear water. The glacial melt that clouds the lake in early summer actually can improve fishing because the fish move shallower and are less spooky, but you will need darker flies and spinners to be visible.

When to fish Lake McDonald

The window for Lake McDonald runs June through September, but timing matters. June and early July bring high water and glacial melt that cloud the lake, making sight-fishing difficult but concentrating fish in clearer pockets near inlet streams. Water temperature is coldest then, which can slow feeding. August and September offer clearer water, more stable conditions, and warmer temperatures that trigger more consistent rises and feeding activity.

September is often the best month — water is clear, air temperatures are mild, and the fish have settled into predictable patterns. October is possible but weather becomes unpredictable, and floatplane charters become less reliable. Plan your trip for August or September if you have flexibility, and expect to adjust your technique and fly selection based on water clarity when you arrive.

Bear safety and food storage

Lake McDonald sits in the heart of Southeast Alaska bear country, and brown bears and black bears both use the area. You must carry bear spray in a holster accessible while walking, and practice drawing it before you arrive. Make noise constantly — talk, use a bear bell, or clap — especially when moving between fishing spots or along the shoreline. Never fish alone if possible, and keep your partner in sight.

Store all food, garbage, and scented items (sunscreen, insect repellent, toothpaste) in bear-resistant containers if you are camping, or hang them at least 12 feet high and 6 feet out from tree trunks using a proper bear hang. Do not cook near your camp if you can avoid it, and never leave fish scraps or bait on the shore. If you encounter a bear, do not run — back away slowly while facing the bear, and use bear spray only if it charges or approaches within 30 feet.

Gear and logistics for a Lake McDonald trip

If you are flying in, weight and space are limited, so pack efficiently. Bring a packraft or inflatable pontoon boat if you want to fish the deeper water and inlets — these pack small and weigh little, and they let you cover more water than shore fishing alone. A small anchor or drift sock helps hold position in wind. Waders and wading boots are essential because the shoreline is rocky and the water is cold year-round.

Bring a headlamp, map, and compass or GPS unit. Cell service is nonexistent. Weather can change rapidly, so pack rain gear and a warm layer even in summer. If you are camping, a lightweight tent rated for wind and a sleeping bag rated for 40 degrees Fahrenheit will handle most nights. Bring a camp stove and fuel — no fires are permitted in many areas of the Tongass, and gathering wood is difficult in wet Southeast climate.

Regulations and permits

Alaska Department of Fish and Game manages the fishery. You need a valid Alaska fishing license, which you can purchase online or at sporting goods stores in Ketchikan or Juneau before you travel. Nonresident licenses are available for 1 day, 3 days, 7 days, or a full year. Check current regulations for bag and possession limits on cutthroat and Dolly Varden — these can change year to year, and some waters have special restrictions.

Lake McDonald itself has no special closures or restrictions that differ from general Southeast Alaska regulations, but always verify current rules with the Alaska Department of Fish and Game or a local ranger station before you go. If you are camping on National Forest land, no permit is required for dispersed camping, but you must follow Leave No Trace principles and pack out all garbage.

Frequently Asked Questions

Can I fish Lake McDonald without a floatplane?

Yes, but hiking in is longer and more difficult than flying. The lake is not on a maintained trail, so route-finding is required and conditions vary seasonally. Most anglers who hike in do so as part of a longer backcountry trip. Contact the Hyder ranger district for current trail information and water crossing conditions before you plan a hiking approach.

What is the best time to visit for clear water?

August and September offer the clearest water and most stable weather. June and July bring glacial melt that clouds the lake, though this can concentrate fish in clearer pockets. September is often ideal — water is clear, temperatures are mild, and fish are feeding predictably.

Do I need a boat to fish Lake McDonald?

A packraft or small inflatable boat lets you reach deeper water and inlet streams, but shore fishing is possible. A boat covers more water and lets you fish drop-offs and structure that are hard to reach from shore. If you fly in, a packraft packs small and weighs little.

What should I do if I see a bear while fishing?

Back away slowly while facing the bear — do not run. Use bear spray only if the bear charges or approaches within 30 feet. Make noise while walking to avoid surprising bears in the first place. Carry bear spray in a holster accessible while fishing, and practice drawing it before your trip.

Are there outfitters or guides who fish Lake McDonald?

Some Southeast Alaska outfitters and floatplane operators know Lake McDonald and can arrange trips, but it is not a heavily guided destination like the Unuk or Salmon rivers near Hyder. Ask floatplane charters based in Ketchikan or Juneau whether they have experience with the lake and can recommend tackle and techniques based on current conditions.
