Clear Lake is a mountain lake 86 mi (138 km) northeast of Eugene, Oregon, United States in Linn County. It has two main bodies connected by a bottleneck. The lake is primarily fed by snow runoff from nearby Mount Washington and the surrounding areas. The runoff filters through caverns for more than 20 years before emptying into Clear Lake. The lake is also fed by two small creeks, which may dry up seasonally, along with Great Spring, the source of the McKenzie River.

Clear Lake is the headwaters of the McKenzie River, which is the sole source of drinking water for Eugene.[1]

Diving

Clear Lake is reported to be one of the most exceptional freshwater dive spots in Oregon.[2] Submerged 100 feet (30 m) deep in the lake is a stand of upright trees that were killed approximately 3,000 years ago when volcanic activity created the lake. The trees are remarkably preserved due to the cold year-round water temperatures of between 35–43 °F (1.6–6 °C).[2]

Hiking

Clear Lake is circled by Clear Lake Loop Trail,[3] a hike loop made up of Clear Lake Trail and McKenzie River Trail that is 5 miles (8.0 km) long. An accompanying trail guide prepared by Willamette National Forest tells visitors about Clear Lake and the neighboring lava field and forest.[4]

Le lac Clear est un lac de montagne situé à 138 km d'Eugene, dans l'État de l'Oregon aux États-Unis. Il est composé de deux bassins principaux reliés par un goulot d'étranglement. Le lac est principalement alimenté par les eaux de ruissellement de la neige à proximité du Mont Washington et les zones environnantes. Les eaux s'infiltrent et ruissellent à travers des cavernes souterraines pendant plus de 20 ans avant de se jeter dans le lac. Le lac est également alimenté par deux petits ruisseaux qui peuvent se tarir suivant la saison.
