California is experiencing its worst drought in decades.

Where do we get our water from?
Woodside, Atherton, Portola Valley and portions of Menlo Park and Atherton are in the Bear Gulch District of California Water Service. CalWater uses both local surface water and surface water purchased from SFPUC. The local surface water, which is about 11% of total water supply, comes from the 1,200-acre watershed in the Woodside hills and is treated at the treatment plant in Atherton.

Most of our water - 89% - comes from the Hetch Hetchy and is stored in the Crystal Springs Reservoir along 280.

Hetch Hetchy

Hetch Hetchy is the name of a valley, a reservoir and a water system. The glacial Hetch Hetchy Valley lies in the northwestern part of Yosemite National Park and is drained by the Tuolumne River.

In 1923, the O'Shaughnessy Dam was completed on the Tuolumne River, flooding the entire valley under the Hetch Hetchy Reservoir. The dam and reservoir are the centerpiece of the Hetch Hetchy Project, which in 1934 began to deliver water 167 miles west to San Francisco and its client municipalities in the greater San Francisco Bay Area.

Hetch Hetchy Valley currently serves as the primary water source for the City and County of San Francisco and several surrounding municipalities in the greater San Francisco Bay Area. The dam and reservoir, combined with a series of aqueducts, tunnels, and hydroelectric plants as well as eight other storage dams, comprise a system known as the Hetch Hetchy Project, which provides 80% of the water supply for 2.6 million people. The project is operated by the San Francisco Public Utilities Commission.

Invest From the Ground Up

Help your trees survive the drought. "Invest From the Ground Up" is a campaign to show Californians how investing in our trees and green spaces creates great neighborhoods. It is a project of the California Urban Forests Council.


Preserve trees, Conserve water. Canopy plants and cares for trees where people need them the most. We bring the life-giving benefits of trees to the schools, neighborhoods, and public spaces of the San Francisco Mid-Peninsula.

We envision a day when every resident of the San Francisco Mid-Peninsula can step outside and walk, play, and thrive under the shade of a healthy tree.

Frank Niccoli's talk "Gardening in a Winter Drought"

February 27, 2014 Frank Niccoli lectured the Woodside-Atherton garden club members on the use of water in our landscapes. Frank is the Founder of the Village Gardener and strives to provide sustainable landscape installation.

California Native Plant Society

The California Native Plant Society provides information on gardening with natives; local conservation projects; and more information on drought resources.


In 1968, we installed a California Native Garden at the Woodside Library to promote the use of California's naturally beautiful and often drought tolerant native plant species. Learn more about drought gardening and plan a visit!
