Named after George Washington, this beautiful freshwater lake covering a surface area of 33.8 square miles is Washington’s second-largest natural lake as well as the biggest lake in King County. The lake is surrounded by the cities of Kenmore on the north, Renton on the south, Kirkland and Bellevue on the east, and Seattle on the west. Lake Washington receives its primary inflows from several rivers and small creeks, including the Sammamish River, Cedar River, Coal creek, Juanita Creek, Kelsey Creek, Ravenna Creek, Thornton Creek, and many more. The Lake Washington Ship Canal links the freshwaters of the lake with the saline waters of Puget Sound.

Created by the Vashon Glaciation, this long, narrow, finger-shaped lake has a maximum length of 22 miles and holds a water volume of 2,842,069 acre-ft. The lake reaches an average depth of 108 ft and a maximum depth of 214 ft. Many fish species are found in the lake, such as coastal cutthroat trout, largemouth bass, yellow perch, black crappie, and rainbow trout.

Nestled on the western slopes of The Enchantments in Washington’s Chelan County is one of the most beautiful alpine lakes in the state. This freshwater reservoir lake is located on the Icicle Creek subbasin’s southeastern corner, about 15 miles from Leavenworth. Depending on the fluctuation of its depth, Colchuck lake covers a surface area of 87.8 acres and reaches a maximum surface elevation of 5,570 ft. The lake’s tributary basin covers 941 acres and has an average storage capacity of 1,570 acre-ft.

In the late 1930s, a masonry dam with a central spillway opening was built to enclose Colchuck Lake and manage the overflow. The dam’s low-level outlet pipeline and slide gate allows controlled release of stored water into an unnamed brook and finally into Mountaineer Creek. This beautiful turquoise-blue lake can be accessed by the Colchuck Lake Trail, which is one of the Pacific Northwest’s most iconic hikes.

Created by the construction of the Diablo Dam on the Skagit River as a part of the Skagit River Hydroelectric Project, Diablo Lake is a popular reservoir lake. This artificial lake is placed at an elevation of 1,201 ft between Ross Lake and George Lake in the Ross Lake Recreation Area within the North Cascades National Park. The distinctive turquoise color of the lake’s water is due to the surrounding glaciers that have grinded rocks into fine rock particles called glacial flour, which reach the lake via creeks. The glacial flour remains suspended and refracts sunlight, giving the lake waters its brilliant hue that looks stunning against the background of magnificent snow-capped mountains.

The Diablo Lake is home to several fish species, including bull trout, brook trout, rainbow trout, and coastal cutthroat trout. The Diablo Lake Trail is a moderate-level hike surrounding the Diablo Lake, and provides hikers with a 7.2 mile round trip experience that gains 1,512 ft in elevation. During the hike to the trailhead, visitors can get amazing views of many minor North Cascades peaks, such as Jack Mountain, Davis Peak, and Pyramid Peak.

This 50.5-mile-long, narrow fjord-like lake is situated in Chelan County in the state’s north-central portion. Covering a surface area of 52.1 square miles, this over-deepened lake has an average width of 1.3 miles and is placed at an elevation of 1,100 ft. Lake Chelan is North America’s third-deepest lake having an average depth of 474 ft and reaching a maximum depth of 1,486 ft. The lake comprises two basins: the lower Wapato Basin and the upper Lucerne Basin. The shallower Wapato Basin covers approximately one-fourth of the total length of the lake, while the much deeper Lucerne Basin occupies the remaining portion. A sill separates the two basins at the narrows, where the lake is only 0.35 miles wide.

The Stehekin River feeds the lake at its northwestern end, while a low dam impounds the lake on its southeastern end, from where a short channel leads to the Columbia River. Several fish species are found in Lake Chelan, including bull trout, longnose sucker, northern pikeminnow, mountain whitefish, Yellowstone cutthroat trout, lake trout, brook trout, chinook salmon, and many more. A significant portion of the lake is situated within the Wenatchee National Forest.

This deep, glacially-carved lake is one of Olympic National Park’s most scenic destinations.

Lake Crescent is Washington’s second-deepest lake having an average depth of 300 ft and a maximum depth of 624 ft.

The lake is well-known for its crystal-clear blue waters, which is mainly attributed to the absence of nitrogen in the water body that inhibits algal growth.

Two endemic fish species are found in Lake Crescent: Beardslee trout and Crescenti Cutthroat Trout.
