Alpine Lake is a reservoir in Marin County, California. Formed by Alpine Dam, it provides water to the Marin Municipal Water District.[3] Below the dam lies Kent Lake.[4] Alpine Lake is to the west of Bon Tempe Lake. Fishing is allowed, and Largemouth Bass, Smallmouth Bass, and trout can be caught. Boats and wading are not allowed on the lake.

## Alpine Dam[edit]

Alpine Dam (national ID number: CA00204) is a gravity dam which was completed in 1917 (106 years ago) (1917). It is 524 feet (160 m) long and 143 feet (44 m) high, with 8 feet (2.4 m) of freeboard.[2]

In 1912, the Marin Municipal Water District, serving San Rafael, the Ross Valley and all of southern Marin, was the first municipal water district to be created in California. One of district's first tasks was to build Alpine Dam to provide drinking water for the county's growing population.[5]

The dam was designed with consultation provided by Michael O’Shaughnessy, who was, at the time, a board member of the district. Construction on Alpine started in the summer of 1917, but the outbreak of World War I led to shortages of labor and materials for the contractor.[5]

In January 1918 district took over the building of Alpine Dam and construction was completed a year later. When first built, the reservoir held just over a billion gallons of water, but the dam was raised in 1924 and again in 1941. The reservoir now has a capacity approaching 3 billion gallons and continues to play a vital role in supplying fresh water to thousands of people in the district.[5]
