Between 1919 and 1923 was constructed the original O'Shaughnessy Dam, named in honor of M. M. O'Shaughnessy, city engin- eer of San Francisco.

Nearby, Lake Eleanor is the second major storage reservoir.

From Early Intake water is carried through 19 miles of tunnels into Priest Reservoir.

Workmen at Moccasin Power House live in a modern village.

At this point surplus water not needed in San Francisco flows back into the Tuolumne River for use of agriculture in the San Joaquin Valley.

47 miles of pipe laid across the San Joaquin Valley bring 70 million gallons of water daily to San Francisco.

This tunnel, 28.5 miles in length, is the longest ev- er driven by man.

At Pulgas Tunnel on October 28, 1934 Hetch Hetchy water was first delivered into the lo- cal water system. Citizens participated in the celebration.
