Most water control projects in the American West depend on huge
gravity dams, whose stability lies in massive quantities of
concrete and earth or rock fill. In the early twentieth century,
John S. Eastwood designed novel dams that minimized the concrete
necessary for construction.
Eastwood's multiple-arch designs proved less expensive than
comparable gravity dams. Yet he faced the opposition of a powerful
cadre of engineers, financiers, and politicians who believed the
distinctive appearance of multiple-arch dams did not inspire public
confidence. Donald C. Jackson offers compelling insight into the
world of America's dam-building elite and describes how proponents
of "bigger is better" dams won out over Eastwood's competing idea
that "bulk does not mean strength."
