Introduction

This is a listing of photographs of dams, reservoirs, and other water-related structures taken by Walter L. Huber. The list supplements our earlier Water resources reports by Walter L. Huber: an annotated listing, Water Resources Collections and Archives Series Report No. 12, May 1962. The materials are in the collection of the University of California's Water Resources Collections and Archives, Berkeley.
All the photos listed here were titled and dated by Mr. Huber. Approximately half of the photos are 4x6 inch prints, the other half are 3-1/2x5 inch. Negatives exist for all photographs.
Walter Leroy Huber was born in San Francisco January 4, 1883. He graduated from the University of California, Riverside in 1905. A long and varied career as engineer included the following hydroelectric and hydraulic assignments and projects: assistant to John Debo Galloway, Galloway & Markwardt Engineering Firm, 1905-1908; U.S. Forest Service, 1910-1913; the California State Department of Public Works, many projects including San Gabriel Dam No. 1 and Central Valley Project; construction engineer for the California Debris Commission on arch dams; member of the board of construction engineers of the U.S. War Department on flood control projects on the Los Angeles, San Gabriel and Santa Ana Rivers including Prado, Sepulveda, Brea, Fullerton, Santa Fe and Whittier Narrows Dams, and in Central Valley, Isabella, Pine Flat and Iron Canyon Dams; construction engineer for the City of San Francisco on Cherry Valley Dam; regional water consultant, National Resources Planning Board; and special consultant on earthquake resistant design of dams.
The earliest photo is dated September 1911 and the last was taken in August 1953.
