Adams Lake is a striking deep-water lake in south-central British Columbia, Canada. This natural marvel lies between the Thompson and Shuswap regions, within the Thompson–Nicola and Columbia–Shuswap regional districts. The lake’s extensive surface area of 137.9 km² and impressive depth of up to 457 meters make it one of the deepest lakes in British Columbia and the world.
The northern stretches of Adams Lake lie within the rugged terrain of the Monashee Mountains, while its southern reaches penetrate the Shuswap Highlands. The lake is easily accessible by Provincial Road 309, located about 79 kilometers northeast of Kamloops. Historically significant, the name “Adams Lake” pays homage to Chief Adam of the Secwepemc people, who was a prominent leader in the mid-19th century and was baptized with the name Adam by Father Nobli. The lake is also known for the rich cultural history of the Secwepemc people, with archaeological evidence of their presence, including winter village sites and pictographs.
Adams Lake was first mentioned in Walter Moberly’s journal in 1865 and appeared in maps produced by George Mercer Dawson in the late 19th century. The lake has remained relatively pristine, maintaining its clear, cold waters fed by tributaries such as the Momich River and Bush Creek. These conditions create an ideal environment for salmon spawning, which is crucial for the region’s ecosystem.
The lake’s basin exhibits a unique and varied geological profile, surrounded by dramatic landscapes of granite igneous intrusions and altered volcanic materials. This unique topography, combined with the lake’s pristine water quality, supports a diverse range of aquatic life, making it a popular spot for fishing, particularly for species like sockeye salmon and rainbow trout.
Adams Lake’s weather is characterized by over 2,000 hours of sunshine annually, moderate rainfall, and significant snowfall in the winter months, making it a year-round destination for outdoor enthusiasts. The area around the lake is known for its mild summers, with average maximum temperatures reaching 28.4°C (84°F), and cold winters, with minimum temperatures dropping to -8.8°C (16°F). Whether you’re a fan of summer hikes or winter sports, Adams Lake has something to offer all year round.
