What You'll Find at Lake Harriet

Lake Harriet sits about 30 miles north of Ketchikan and holds both saltwater and freshwater fishing depending on where you fish and the tide. The lake connects to saltwater through a narrow channel, so the upper portions stay fresh while the lower end and tidal areas mix. You can fish for Dolly Varden char, cutthroat trout, and pink salmon in the freshwater sections, and halibut, lingcod, and rockfish in the saltwater portions when tides are right.

The lake is accessible by floatplane or boat from Ketchikan, and most anglers charter a flight or arrange water taxi service rather than attempt the overland route. The setting is typical Southeast Alaska — forested shoreline, rocky points, and shallow bays that hold fish in different seasons. Summer brings the most consistent fishing and the easiest travel conditions, though spring and fall can be productive if you're willing to deal with weather.

Key Takeaways

  • Lake Harriet holds Dolly Varden and cutthroat trout year-round in freshwater sections, with pink salmon runs in summer and early fall.
  • The lower lake and tidal channels hold saltwater species including halibut and lingcod, accessible at high tide or by boat.
  • Floatplane or water taxi from Ketchikan is the standard way to reach the lake; no road access exists.
  • Summer offers the most reliable fishing and weather, but spring and fall can produce good results with proper planning.
  • Bring saltwater and freshwater tackle, as the same trip often involves both depending on tide and location.

Freshwater Fishing for Char and Trout

The upper lake and inlet streams hold Dolly Varden year-round, with the best fishing in spring and fall when water temperatures drop and fish move into shallower areas. Dolly Varden at Lake Harriet run small to medium — most fish fall between 8 and 14 inches — but they're aggressive and willing to take small spoons, spinners, and flies. Fish the rocky points and current breaks where the inlet feeds the lake, especially during the first two hours of an incoming tide.

Cutthroat trout are present but less abundant than Dolly Varden. They prefer the quieter bays and the mouths of small streams that feed the lake. A 5 or 6-weight fly rod works well for both species, and small streamers in black, olive, or white imitate the baitfish both species hunt. If you're spinning, use 1/8 to 1/4 ounce spoons in silver or gold, and work them slowly along drop-offs and structure.

Pink Salmon Runs and Timing

Pink salmon enter Lake Harriet in mid-summer, typically peaking in July and August. The run is not as heavy as some Southeast Alaska systems, but fish are present and willing to take small spoons and flies. Most pinks run 3 to 5 pounds, making them fun on light tackle and a good target if you want action rather than trophy size.

Time your trip for late June through August if pink salmon are your main target. The fish move through the lower lake and inlet quickly, so location matters — focus on the channel connecting the lake to saltwater and the areas where streams enter the main basin. Early morning and evening produce better than midday, and overcast days often see more activity than bright sun.

Saltwater Fishing in the Lower Lake and Tidal Channels

The lower portions of Lake Harriet and the channel connecting to open water hold halibut, lingcod, and various rockfish species. Halibut fishing is best at slack tide or during the first hour of an incoming tide, when fish move into shallower water to feed. Jigs in the 2 to 4-pound range work well, and you can also fish live herring if you bring bait with you or catch it locally.

Lingcod are aggressive and abundant in rocky areas and around kelp beds near the mouth. They'll take jigs, live bait, and even small swimbaits. Rockfish species including yelloweye, quillback, and canary are common in deeper water and around structure. All three species require saltwater tackle — bring a medium-action spinning rod or light jigging rod rated for 15 to 30-pound line, and plan to fish deeper water (40 to 100 feet) where these fish hold.

Getting There and Planning Your Trip

Floatplane is the most common way to reach Lake Harriet from Ketchikan. Several air services operate from Ketchikan International Airport, and flights typically take 20 to 30 minutes depending on weather and exact landing spot. Water taxi services also run from Ketchikan, though they take longer and depend on tide and sea conditions. Expect to pay between $300 and $500 for a round-trip floatplane charter for one or two anglers, or $150 to $250 per person on a shared water taxi.

Plan for at least two full days of fishing to make the trip worthwhile. Many anglers book a lodge or cabin near the lake rather than day-tripping, which gives you flexibility to fish different areas and adjust to weather. Bring rain gear, warm layers, and bug spray — Southeast Alaska weather changes fast, and mosquitoes can be heavy in summer. If you're fishing both freshwater and saltwater, pack two complete rod setups rather than trying to swap tackle between trips.

Seasons and Weather Considerations

Summer (June through August) offers the most stable weather and the longest daylight, making it the easiest time to fish. Water temperatures are warmer, fish are more active, and floatplane service is most reliable. July and August are peak season, so book your charter early if you're planning a specific date.

Spring (April and May) can produce excellent fishing for Dolly Varden and cutthroat, but weather is unpredictable and floatplane service may be delayed by fog or wind. Fall (September and October) brings cooler water and active fish, but daylight shortens quickly and storms become more frequent. Winter fishing is possible but rarely attempted by visiting anglers due to weather and limited daylight.

What to Bring and Local Regulations

Alaska fishing regulations require a valid Alaska fishing license for all anglers 16 and older. You can purchase a non-resident license online through the Alaska Department of Fish and Game website before you travel, or buy one in Ketchikan. Bring your license with you — enforcement is active in Southeast Alaska, and fines for fishing without a license are substantial.

Pack freshwater and saltwater tackle separately, as you'll likely fish both during a trip. Bring more flies and spoons than you think you'll need — snags on rocks and kelp are common, and resupply options don't exist at the lake. A net is helpful for landing fish, especially if you're fishing from a boat. Bring polarized sunglasses to spot fish in shallow water, and a headlamp for early morning or evening fishing during summer when darkness is brief.

Frequently Asked Questions

Can I fish Lake Harriet without a guide?

Yes, but you'll need to arrange your own floatplane or water taxi to reach the lake. Once there, you can fish on your own. Many anglers hire a local guide for the first day to learn productive areas and techniques, then fish independently afterward. A guide typically costs $300 to $500 per day.

What's the best time to catch halibut at Lake Harriet?

Slack tide and the first hour of an incoming tide are most productive. Halibut move into shallower water to feed during these windows. Fish the lower lake and the channel connecting to saltwater, focusing on depths between 40 and 80 feet.

Do I need to bring my own tackle or can I rent it in Ketchikan?

Tackle rental is available in Ketchikan, but selection is limited and prices are high. Bringing your own gear is more practical. If you fly in without tackle, several shops in Ketchikan can rent rods and reels or sell basic supplies before your floatplane departs.

How many fish can I keep from Lake Harriet?

Bag limits vary by species and change annually. Check the Alaska Department of Fish and Game website or your current fishing regulations pamphlet before you go. Generally, Dolly Varden and cutthroat have daily limits of 5 fish, pink salmon limits are 6 fish, and halibut has a possession limit but no daily bag limit. Lingcod and rockfish have daily limits as well.

What if weather cancels my floatplane?

Floatplane cancellations due to weather are common in Southeast Alaska. Most air services will reschedule your flight at no charge, but you may lose a day of fishing. Book your trip with extra days built in if possible, and purchase trip insurance if you're concerned about weather delays.
