1967. , 66 pages.Brief technical data, photos and layout schemes on dams in exploitation or under construction are stated. The dams (both for hydropower and water supply purposes) comprise:
Amistad,
Carters,
Dworshak,
Glen Canyon,
Kinzua,
Morrow Point,
Mossyrock Hydroelectric Project,
New Exchequer,
Nickajack,
Oroville,
Round Butte,
San Luis,
Wells Hydroelectric Project (Note A.P. – famous Wells HPP), and
Yellowtail.Preface.
The United States Committee on Large Dams has undertaken herein to present a group of fourteen large dams as representative of current practice of dam design and construction in the United States. Some of these projects have been completed, but most are still under construction. Each has been chosen to be representative of advanced design or construction techniques.
ariety was an objective in their selection—particularly a variety that would evidence the great breadth of today's dam design and construction practice in the United States. Not all of these will go down in history as among the world's greatest. But all are important projects, and each is making its contribution to the increasing fund of knowledge from which the world's dam designers and builders are now able to draw.
t will be recognized that some of the construction concepts have been adapted from those used in other countries, not only in the construction of dams but also in other construction as well. It may be significant that eight of the fourteen dams described are of earthfill or rockfill construction. Certainly the adaptability of this type of construction, where it may be feasible, has provided many economical and adequate structures.
The Oroville Dam (776 feet high) will, for awhile, be the world's highest earthfill, and thus provides an expression of expansion in this art. On the other hand Glen Canyon (a 710-foot high concrete dam) is included, for concrete will continue to be one of the very important dam building materials.
This contribution is offered in the spirit of one of the basic objectives of the International Commission on Large Dams ". . . to encourage improvements in the design and construction. . " of large dams.
t should be particularly noted that this is not an attempt to select dams of merit in any competitive sense, but simply to offer a cross-section of important dams recently built or now under construction in the United States.
am glad to have this opportunity to thank and commend the authors and their organizations for their contributions to this publication, and also I wish to thank the special committee of the United States Committee on Large Dams which was responsible for the production of this booklet, which included the following: Floyd P.
