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 underground 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. Clear Lake is the headwaters of the McKenzie River, which is the sole source of drinking water for Eugene.〔(【引用サイトリンク】url=http://www.mckenziewaterquality.org )〕 ==Diving== Clear Lake is reported to be one of the most exceptional freshwater dive spots in the United States.〔(【引用サイトリンク】title=Clear Lake Resort )〕 Submerged 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).〔
