Testing the subsurface for the Bureau of Reclamation


Established in 1902, the U.S. Bureau of Reclamation was chartered to manage, develop, and protect water resources in the American West. Among the activities of the Bureau is the construction of dams, canals, and power plants. Walter J. Lubken, a staff photographer for the Bureau, captured a crew from its Boise Project using diamond drills to test the subsurface in August 1910.
