Lake Alpine, reservoir in Alpine County, California, United States

Lake Alpine is a reservoir in Alpine County, California, located at about 7,300 feet (2,200 meters) elevation in the Sierra Nevada. The lake covers roughly 179 acres and was created by a dam on Silver Creek, with several small islands dotting its surface.

Originally called Silver Valley Reservoir, the lake was created in 1892 when the Utica Mining Company dammed Silver Creek to supply water for mining operations in Angels Camp. The area later developed into a recreation destination as summer homes and mountain cabins appeared throughout the 20th century.

The reservoir takes its name from its setting in the Sierra Nevada, and the surrounding community along California State Route 4 shares the name Lake Alpine. In summer the water draws boaters and hikers, while winter brings snowmobilers and skiers; snow can block access at times.

The lake is easily accessible via California State Route 4, roughly 50 miles east of Angels Camp. A two-mile paved trail circles the lake and is wheelchair accessible, while restrooms are available on-site but visitors should bring their own drinking water.

California State Route 4 runs north of the reservoir between Bear Valley and Pacific Grade Summit, passing through the unincorporated community also called Lake Alpine. The reservoir sits at 7,303 feet (2,227 m) above sea level, and snow can block access at times. Silvertip Campground is one of several campgrounds around the shore.
