Lake Chelan

Lake Chelan’s extraordinary length and depth create two distinct ecological zones with different wildlife communities. The south end (Chelan area) — in the rain shadow of the Cascades, receiving less than 12 inches of rain per year — supports a Columbia Basin semi-desert wildlife community: rattlesnakes, western fence lizards, California quail, coyotes, mule deer, and the abundant lake-bird community (western grebes, common loons, ospreys, and bald eagles). The north end (Stehekin area) — in the wetter, cooler North Cascades climate — supports a temperate rainforest wildlife community: black bears (abundant; proper food storage required at all campsites), mountain lions, moose (the Stehekin River valley has an excellent moose population), bald eagles, harlequin ducks, common mergansers, dippers, and the full suite of North Cascades forest birds (varied thrush, Townsend’s warbler, and Swainson’s thrush are characteristic). The ferry ride up the lake traverses this ecological transition in real time.

The ferry to Stehekin is the primary transportation; if you miss the last ferry south from Stehekin, you are staying another night (there is no road out). Know the ferry schedule and be at the dock 30 minutes before departure. The lake can develop significant waves in afternoon winds (the lake’s 55-mile fetch allows wind waves to build to 3-4 feet in strong conditions; the ferry is large and safe but small personal watercraft should be pulled from the water by early afternoon). Black bears in the Stehekin River valley are habituated to human food sources; store all food in bear boxes or bear canisters at all times. The North Cascades wilderness trails from Stehekin involve serious elevation gain (3,000-5,000 feet to reach the high passes) and require full mountain preparedness. Rattlesnakes are present on the south end of the lake near Chelan; watch where you step in the dry scrublands.

Lake Chelan’s Chelan trough was carved by the Chelan Valley Glacier during the Pleistocene ice ages and has been inhabited by the Chelan people (a Salish-speaking band of the Interior Salish people known as the Chelankees) for thousands of years; the Chelan people fished the lake’s salmon runs, gathered roots and berries in the surrounding valleys, and maintained trade connections with the Coast Salish peoples to the west and the Plateau peoples to the east. Euro-American settlers arrived in the Chelan Valley in the 1880s; the town of Chelan grew as an agricultural community (apple orchards in the lake’s warm microclimate) and as a resort destination (steamboat service on the lake to Stehekin was established in the 1890s; the journey to Stehekin has been a Washington State travel experience for more than 130 years). The Lake Chelan National Recreation Area (administered by NPS as part of the North Cascades Complex) was established in 1968; Stehekin’s unique character as a road-free, NPS-managed community has been preserved since the recreation area’s establishment.

Lake Chelan occupies a glacially overdeepened trough — one of the most dramatically overdeepened glacial valleys in North America. The Chelan Valley Glacier (a major outlet glacier from the Pleistocene Cordilleran Ice Sheet) carved the Chelan trough to a depth of 400 feet below sea level (the current lake floor depth is approximately 400 feet below sea level at its deepest point near Lucerne, despite the lake surface sitting at 1,100 feet above sea level; this is possible because the glacier’s ice weight and erosive power carved the rock far below the level of any reasonable postglacial equilibrium). The lake is now impounded at its south end by a natural moraine dam (supplemented since 1927 by the Lake Chelan Dam, which controls the lake level for power generation). The surrounding mountains are composed of the Chelan Mountains Terrane — a complex of Mesozoic metamorphic rocks and Cretaceous granodiorite intrusives, all part of the Cascades crystalline core.

Lake Chelan’s ecology is shaped by the lake’s extraordinary physical properties — its great depth (1,486 feet) creates a thermal stratification (a thermocline) that separates the warm surface layer from the permanently cold deep water; this stratification restricts nutrient mixing and makes the lake one of the most oligotrophic (nutrient-poor and thus highly clear) large lakes in the western United States. The lake’s clarity (visibility to 70+ feet in some seasons) is a function of the nutrient poverty; the water is cold, clear, and beautifully transparent in the deep mid-lake sections. Introduced lake trout and chinook salmon dominate the deep-lake fish community; the native Westslope cutthroat trout has been largely displaced by introductions. The Stehekin River delta at the lake’s north end is one of the finest examples of an active alluvial fan in the North Cascades; the river’s sediment load is gradually building the delta into the lake.

Lake Chelan occupies a singular place in Washington State’s outdoor culture — the deepest lake in Washington and the third-deepest in the United States, a 55-mile glacial fjord spanning two entirely different worlds (the sunbaked Columbia Basin resort at the south end; the remote North Cascades wilderness at the north end), the ferry journey to the road-free village of Stehekin (a journey that has been a Washington State travel experience for more than 130 years), and a wine-country resort destination of increasing national recognition. Lake Chelan’s combination of scale, depth, ecological diversity, wilderness access, and resort character makes it one of Washington’s most distinctive and most beloved natural destinations.

Lake Chelan is accessed from the town of Chelan, Washington, approximately 180 miles east of Seattle via US-2 east over Stevens Pass and WA-150, or via I-90 east and US-97 north. Chelan has full resort services (hotels, restaurants, wineries, the ferry terminal). The Lady of the Lake and Lady Express ferries to Stehekin depart from the Chelan ferry dock (reservations required; book at ladyofthelake.com months in advance for summer dates). Floatplane service to Stehekin is available from Chelan via Chelan Seaplanes. Stehekin has limited services (the Golden West Visitor Center [NPS], a bakery, a small store, a restaurant, and the NPS-operated Stehekin Landing campground and lodging; no bank, no gas station, no major retail). A Northwest Forest Pass or America the Beautiful Pass is not required for the ferry or for NPS lands in Stehekin (no entrance fee for the Lake Chelan NRA). Check ladyofthelake.com for current ferry schedule and fares before planning your trip.

The National Park Service manages the Lake Chelan National Recreation Area (the north end of the lake, including Stehekin). The most critical conservation priority is maintaining the road-free, wilderness character of the Stehekin community and the North Cascades wilderness accessible from it; the ferry visitation model (limited daily ferry capacity naturally constrains visitor numbers) has been the primary tool for managing visitation. Black-bear food storage (required at all North Cascades NPS campgrounds; use designated bear boxes at designated campgrounds; use a bear canister for dispersed camping) is the most important visitor-behavior requirement in Stehekin. The lake’s exceptional water clarity is a conservation asset; no motorized watercraft with two-stroke engines are permitted on the lake (check current regulations for clean-water requirements). Pack out all trash from Stehekin and any dispersed camping in the wilderness.

Ferry reservations required for summer dates (book at ladyofthelake.com months in advance; summer departures fill quickly). No entrance fee for Lake Chelan NRA. Backcountry permits required for overnight camping in the North Cascades Wilderness accessible from Stehekin (check NPS for current permit requirements and quotas). Black-bear food storage required at all campsites in the NRA. Clean-water regulations apply to motorized watercraft on the lake (check WDFW for current engine regulations). Washington State fishing license required for fishing in the lake. No camping at the Stehekin ferry dock area except in designated NPS campgrounds. Pack out all trash.

The town of Chelan, Washington (the south-end gateway — a full resort town with excellent lodging, restaurants, and the Lake Chelan Wine Valley AVA with 30+ wineries producing excellent Riesling, Syrah, and other varietals in the lake’s warm microclimate), Wenatchee (45 miles south — the “Apple Capital of the World” — and the Columbia River gateway city), North Cascades National Park (accessible from Stehekin via the Stehekin River Trail and shuttle bus — the Cascade Pass trailhead is accessible by shuttle from Stehekin; the finest North Cascades wilderness trail), the Methow Valley (WA-20 east — 50 miles north of Chelan via US-97 and WA-153 — with Winthrop and the Methow Valley ski trails), and the Wenatchee National Forest (surrounding the lake’s east and south shores — excellent mountain biking and hiking) define the region. Lake Chelan is the gateway between Washington’s dry, sunny east side and the North Cascades wilderness.

Book the Lady Express ferry for an overnight stay in Stehekin — the 2-3 hours provided by the day-trip schedule is genuinely insufficient to experience the Stehekin valley; an overnight at the Stehekin Valley Ranch or the NPS campground gives you a full day to hike the Agnes Gorge Trail (the finest single day hike in the Stehekin valley — 5 miles round trip through old-growth cedar and Douglas-fir to the extraordinary glacial gorge of the Agnes Creek) or the Rainbow Loop, and to take the NPS shuttle bus 23 miles up the Stehekin River valley to the Horseshoe Basin trailhead. Reserve your ferry tickets and any Stehekin lodging or camping 3-6 months in advance for July and August dates — they sell out completely. The Stehekin Pastry Company (the bakery at the Stehekin dock) makes the finest cinnamon rolls in Washington State; order them the evening before your planned departure for an early-morning pickup before the southbound ferry.
