Lake Willoughby
Lake Willoughby is Vermont's deepest lake and its most dramatic, a glacial fjord pinched between the sheer cliffs of Mount Pisgah and Mount Hor. Its cold, smelt-rich depths have produced state-record lake trout and support salmon, rainbows, and browns, making Willoughby the flagship stillwater of the Northeast Kingdom.
Overview
Lake Willoughby fills a glacially carved trench in the town of Westmore, its 1,687 acres squeezed into a narrow five-mile ribbon between Mount Pisgah and Mount Hor. The cliffs plunge nearly straight into the water at the south end, and the lake bottom keeps falling: at more than 300 feet, Willoughby is the deepest lake lying entirely within Vermont and one of the deepest in New England. The setting has earned it comparisons to a Norwegian fjord, and the fishery lives up to the scenery.
The story of Willoughby is a coldwater story. The lake stays frigid and well-oxygenated top to bottom, and its foundation is an abundant population of rainbow smelt. That forage base grows lake trout to exceptional size; Willoughby has produced Vermont's state-record lake trout and continues to give up fish in the double digits every season. Landlocked Atlantic salmon, rainbow trout, and brown trout round out a true two-story fishery, with salmonids working the smelt schools from ice-out into early summer.
For fly anglers, the prime window opens the moment the ice leaves, typically mid to late April. For four to six weeks, lake trout, salmon, and rainbows cruise the surface layer and shoreline shelves chasing spawning smelt. This is when a fly rod is genuinely competitive with any method on the lake: trolling or casting smelt streamers like the Grey Ghost on sinking lines along the drop-offs at the north and south ends produces the best fish of the year. As the thermocline sets up in late June, the lake trout retreat beyond practical fly range, but salmon and rainbows still show early and late in the day.
Summer fly fishing turns to the margins: chironomid emergences over the shallower northern shelf, evening midge clusters on calm water, and leech and bugger work along the weedlines at each end of the lake. Fall brings salmonids back toward the surface and toward the mouths of tributaries as temperatures drop, and October can feel like a second ice-out for streamer anglers willing to brave the Kingdom wind.
Willoughby is big, deep, and frequently windswept; a boat or kayak transforms the fishing, though the accesses at the north and south ends both offer legitimate shore and wading opportunities over gravel shelves. The Willoughby is not numbers water. It is a place to hunt a genuinely large fish in one of the most beautiful settings in the East, and every serious New England stillwater angler should make the pilgrimage at ice-out at least once.

Water Characteristics
Willoughby is a cold, deep, oligotrophic glacial lake with remarkable water clarity; visibility of 20 feet or more is common. The basin is a steep-sided trench, with the bottom dropping quickly from narrow shoreline shelves into very deep water, especially along the cliff faces of Pisgah and Hor at the south end. The broader, shallower shelves at the extreme north and south ends hold most of the weed growth and insect life.
The forage base is dominated by rainbow smelt, which drive the behavior of every gamefish in the lake. Chironomids are the most important insect, with midge activity spring through fall; the shallow ends also hold damselflies, dragonflies, and leeches. Wind funnels down the lake's north-south axis almost daily, and conditions can change from flat calm to whitecaps in minutes.

Seasonal Fishing Guide
Spring
Ice-out (mid to late April) through early June is the prime fly window. Lake trout, salmon, and rainbows follow spawning smelt into the top 15 feet of water and along shoreline shelves. Cast or troll Grey Ghosts and other smelt streamers on full-sinking or fast-sink-tip lines along the drop-offs at the north and south ends. Cold, windy days are often best; work the wind-blown shorelines where smelt stack up.
Summer
Once the thermocline forms in late June, lake trout drop beyond fly range. Shift to early-morning and evening chironomid fishing over the northern shelf, midge clusters on flat calm evenings, and leech patterns along weed edges. Salmon and rainbows still take streamers at first light before recreational boat traffic builds.
Fall
September and October bring salmonids back up in the water column. Streamer fishing improves steadily as surface temperatures fall through the 50s, and fish concentrate off tributary mouths and gravel shorelines ahead of spawning. October on Willoughby is cold, windy, and frequently outstanding.
Winter
Ice fishing for lake trout is a Willoughby tradition, with jigging spoons and smelt-imitating jigs over 60-150 feet of water. The lake's depth means late ice-in; verify safe ice and current season dates before venturing out.
Access & Boats
Public boat launch and beach at the north end in Westmore off Route 5A, and a second access with launch at the south end. Route 5A parallels the eastern shore with several pulloffs. Shore and wade fishing possible over the gravel shelves at both ends; a boat is a major advantage on this large, deep lake.
Ice Fishing
Willoughby is one of Vermont's premier ice fisheries for lake trout, with jigging over deep structure producing fish through the winter season. Deep water and wind keep ice conditions variable near the cliffs; the north end sets up first. Check current ice fishing season dates for trout and salmon.
Fishing Pressure & Local Tips
Moderate overall, and light for fly anglers specifically. Willoughby sees steady troller traffic at ice-out and a busy summer recreation season, but the fly fishing pressure is minimal compared to Vermont's name rivers. Ice fishing season draws a dedicated lake trout crowd. Weekday mornings at ice-out, an angler casting streamers from a boat or the shelves often has the water to themselves.
Local Knowledge
Time your trip to ice-out. Call local shops or watch NEK ice-out reports in April; the two to three weeks after the ice leaves are worth more than the entire rest of the summer for a fly angler chasing lake trout and salmon. Fish smelt patterns 3 to 5 inches long, and do not be shy about a fast retrieve; salmon in particular respond to a stripped fly moving with purpose.
Respect the wind. The fjord topography accelerates any breeze down the lake's axis, and small craft should stay close to the ends rather than attempting the mid-lake cliff sections. When the wind is up, fish the wind-blown north or south shore; smelt and baitfish get pushed against those shelves and the predators follow.
Species Present

Lake Trout
The lake trout is the largest member of the char family and the signature deep-water gamefish of northern New England's coldest, cleanest glacial lakes. A native coldwater char of the northern tier of North America, the lake trout reaches the southern edge of its natural range in the deep, oligotrophic lakes carved by Pleistocene glaciers across northern New England, including Vermont's Lake Champlain and the remote glacial lakes of the Northeast Kingdom. Unlike the stream-dwelling brook trout to which it is related, the lake trout is a true creature of the depths, spending most of the year in the cold, dark, well-oxygenated water far below the surface. Lake trout are long-lived, slow-growing fish that can survive for decades in the frigid depths of their home lakes. Average fish run 18 to 24 inches, but trophy specimens exceeding 30 inches and 15 pounds are taken each season from the best Vermont waters, and the state record approaches 35 pounds. Their size and strength, combined with the challenge of reaching them in deep water, make lake trout a prized quarry for anglers willing to adapt their tactics to the fish's coldwater lifestyle. For fly anglers, the lake trout presents a unique seasonal opportunity. Through most of the year these fish hold too deep for practical fly fishing, but during the narrow windows of ice-out in spring and the fall turnover, lake trout move into the shallows to feed and spawn, bringing them within reach of a well-presented streamer. Casting large baitfish patterns near rocky shorelines and drop-offs during these periods can produce the fish of a lifetime, connecting the angler to the deep glacial history of Vermont's finest coldwater lakes.

Rainbow Trout
The rainbow trout is Montana's most widespread and popular gamefish, celebrated for its explosive surface strikes, aerial acrobatics, and willingness to take a well-presented dry fly. Native to Pacific Coast drainages from Alaska to Mexico, rainbows were first introduced to Montana's waters in the late 1800s and have since established thriving populations in nearly every major river system in the state. On legendary waters like the Madison, Missouri, and Bighorn, wild rainbow trout grow fat on prolific insect hatches and provide some of the finest dry-fly fishing in North America. Rainbow trout in Montana display remarkable variation depending on their home water. Fish in nutrient-rich tailwaters like the Missouri River below Holter Dam can exceed 20 inches with regularity, their deep bodies and broad tails reflecting the abundant food supply. Freestone river rainbows, such as those in the upper Madison and Gallatin, tend to be leaner and more athletic, shaped by faster currents and colder water temperatures. In many Montana rivers, rainbows spawn in the spring from March through June, and anglers should be mindful of spawning redds during this period to protect future generations of fish. Rainbows are arguably the most versatile trout species for fly anglers. They respond well to dry flies during hatches, aggressively chase streamers, and feed heavily on nymphs subsurface throughout the year. Their fighting ability is legendary: a hooked rainbow will often launch itself completely out of the water multiple times during a battle. Montana's catch-and-release regulations on many blue-ribbon streams have produced exceptional rainbow trout fisheries with high densities of large, healthy fish that continue to draw anglers from around the world.

Landlocked Atlantic Salmon
The landlocked Atlantic salmon is one of New England's most prized gamefish, a freshwater-resident form of the Atlantic salmon that spends its entire life in lakes and rivers rather than migrating to the ocean. Found primarily in the lakes and rivers of Maine, New Hampshire, Vermont, and New York, landlocked salmon are genetically identical to their sea-run counterparts but have adapted to a completely freshwater life cycle, using large, cold lakes as their ocean substitute and tributary rivers as spawning habitat. Landlocked salmon are the signature gamefish of Maine's sporting camp tradition, where generations of anglers have gathered at remote wilderness lodges to fish for salmon in the Rangeley Lakes, Moosehead Lake, Sebago Lake, and the rivers that connect them. The fish combine the acrobatic fighting ability of their anadromous relatives with the accessibility of a freshwater species, leaping repeatedly when hooked and running with the kind of power and endurance that makes them one of the most exciting fish available on a fly rod in the northeastern United States. In rivers, landlocked salmon behave much like large resident trout, holding in classic lies and feeding on aquatic insects during hatches. They are particularly responsive to caddis and mayfly emergers, and the sight of a 3-pound landlocked salmon rising to a dry fly in a New England river is one of the defining experiences of northeastern fly fishing. In lakes, salmon are targeted with streamers that imitate smelt, their primary forage fish, trolled or cast from boats during the spring and fall when salmon cruise near the surface in cold-water conditions.

Brown Trout
The brown trout is the most cunning and elusive trout species swimming in Montana's rivers, and it rewards patient, skilled anglers with some of the state's most memorable catches. Originally native to Europe and western Asia, brown trout were first introduced to North American waters in 1883 and arrived in Montana shortly thereafter. They have since established robust, self-sustaining populations in virtually every major trout stream in the state, from the legendary spring creeks of the Paradise Valley to the sweeping runs of the lower Madison and the deep pools of the Bighorn. Brown trout grow larger than any other trout species in Montana, and fish exceeding 24 inches are caught with regularity on premium waters. The lower Madison River, the Missouri River below Holter Dam, and the Bighorn River are particularly renowned for producing trophy-class browns. Unlike rainbows, brown trout spawn in the fall (October through November), and their aggressive pre-spawn behavior creates an exciting window for streamer fishing as large males become territorial and attack anything that enters their domain. Browns are notably more nocturnal than other trout species, and many of the biggest fish are caught during low-light conditions. What sets brown trout apart from other species is their wariness and selectivity. Large browns are notoriously difficult to fool, often refusing flies that are even slightly off in size, color, or presentation. They tend to establish and defend prime feeding lies (undercut banks, logjams, deep pools, and boulder gardens), and an angler who learns to read water and identify these holding spots will consistently catch more and larger fish. This combination of difficulty, size potential, and intelligence makes the brown trout the most prized quarry for many serious Montana fly fishers.

Access Points & Boat Launches
Willoughby North Beach & Boat Launch
Boat LaunchEasyPublic beach and boat launch at the north end of the lake in Westmore village off Route 5A. The broad northern shelf here is the lake's best shore-casting water at ice-out, with gravel flats dropping to the first break within casting range. Primary launch for boats working the smelt run.
Willoughby South End Access
Boat LaunchEasyAccess and small beach at the south end beneath the cliffs of Mount Pisgah and Mount Hor. The southern shelf concentrates smelt and cruising salmonids in spring and fall, and the dramatic fjord scenery is unmatched. Cartop and small trailer boats launch here; wind funnels hard down the lake, so plan around the forecast.
Route 5A Shoreline Pulloffs
Wade AccessEasy to ModerateMultiple pulloffs along Route 5A on the eastern shore providing bank-casting access to drop-offs that plunge quickly to deep water. Streamer anglers reach cruising fish from shore at ice-out and in October where the shelf narrows. Watch traffic and use established pulloffs only.
