Map of the Spring Valley Water Works compiled from actual surveys
Bringing water from Calaveras Reservoir to Crystal Springs – Spring Valley Water Works pipe line map.
Produced under the direction of Hermann Schüssler, the famous chief engineer of the Spring Valley Water Works, this map is designed to highlight the potential for the Calaveras Reservoir in supplying water to the city of San Francisco. Water was to be brought from Calaveras via a new pipe line running along the southern edge of the Bay, north of Santa Clara and San Jose.
The map illustrates the extensive network of supply lines already in existence from Crystal Spring to San Francisco. Railroads and towns are also shown, along with important topographic features.
