Island Lake (Nevada)

Island Lake is a glacial tarn in the Ruby Mountains of Elko County, Nevada, United States. It is within the Ruby Mountains Ranger District of the Humboldt-Toiyabe National Forest. The lake is a hanging valley at the end of a 2 mi trail that begins at a parking lot at the end of Lamoille Canyon Road. The lake surface is 9665 ft above sea level, about 910 ft above the parking lot.

Island Lake has an area of approximately 7.5 acre and a depth of up to 22 ft. It is a popular site for day trips, fishing, and camping.

Island Lake is a minor source of flow for Lamoille Creek, which after exiting the mountains passes through the town of Lamoille, meanders down Lamoille Valley, and then merges with the main branch of the Humboldt River.
