It was built to create a reservoir for downstream irrigation uses in Redlands, resulting in the largest man-made body of water in the world at the time. When Frank E. Brown engineered this dam, he couldn't possibly have envisioned the role Big Bear Lake would play in the future development of the surrounding mountain communities. The storage capacity of the newly created Lake was 25,000 acre feet (one acre foot is enough water for a family of four for one year). Many engineers claimed that this single arch granite dam would not hold. Sometime later, those same doubting engineers Read More Go to Site Brief Description of Building the Ultimate Dam Votes:0 A BRIEF DESCRIPTION OF BUILDING THE ULTIMATE DAM In exploring the world of dam building and water control in the American West prior to the New Deal, this book focuses on the work of John S. Eastwood, an early twentieth century engineer who aggressively promoted the dramatically less expensive -- and controversial -- multiple arch dam. Placing Eastwood's work within a vibrant milieu, replete with power struggles among engineers, corporate patrons and government bureaucrats, Donald C. Jackson's Building the Ultimate Dam illustrates how both technical and nontechnical issues have affected -- and controlled -- the financing and construction of dams. Using more than 150 photographs and drawings, Jackson traces Eastwood's early career from his tenure as Fresno's first City Engineer, through wor Read More Go to Site BUILDING BIG: All About Dams Votes:0 --> Dam Basics Learn the basics about the biggest -- and costliest -- structures we build.

The dam was needed both for the generation of hydroelectric power and for the diversion of water to the cities and farms of southern California. One of the engineers on the project later described the challenges the builders faced: "Sheer canyon walls so high that they distorted perspective; the lack of even a sand bar for initial footage; the desert on each side without housing or transportation facilities; and greatest of all, the terrific current of the silt-filled river."

DAMS When the first dam was founded by Theodore Roosevelt, America's first great conservationist President, the way dams change river systems and their wildlife was not well understood. Today, after decades of study, we know a great deal more about these impacts. With that knowledge comes a greater responsibility and trust. The river systems in which dams operate are home to thousands of species, millions of trees, priceless mountains, plains, canyons, and deserts unlike any other in the world. Dams help preserve wetlands, add to instream flows, preventing groundwater contamination, control water salinity, control sources of pollution, and conserve and enhance fish and wildlife habitats.

Earth and rock construction was chosen because foundation conditions and the abundance of local materials made it more cost-effective than concrete. All soil products were obtained on-site or from the Reading area.

But for any but a very narrow valley this would not work. This dam has both gravity and arch action, though with this width and with the type of local rock, it could not have been built purely as an arch dam. Here are pictures of the beautiful Slap Savica in the Triglav National Park, Slovenija. The dam has only slight curvature, and probably acts mainly as a gravity dam. The vertical cross-section suggests that a gravity dam is rather like a cantilever. It is held to the valley floor by gravity. It is very important that all water be excluded from underneath a gravity dam. A boat can in principle float in a cavity that exceeds Read More Go to Site IdahoPTV Building Big Votes:0 North Idaho N.

It is an earth dam, 10m high, and has been in regular operation up to now. The later Zhibo irrigation canal in Shanxi Province (453BC) and Dujiangyan irrigation project in Sichuan Province (219BC) are very famous engineering works, especially the invented masonry spillway dam, 3.8m high, on the navigation canal in Guangxi Autonomous Region which was constructed in 219 BC and is still operating now.

No dam of this scale had been attempted before; that fact that technological innovations were required to build it was understood implicitly. In this context, though, the word modern simply implies advancement, an adherence to the forward-looking quality of design as new materials and new techniques became available through the first half of the twentieth century. The Hoover Dam also became an icon of modernism, that certain mode of design which emerged from Europe in as disparate forms as Gropius's Bauhaus or the 1925 Paris Arts Decoratif et Industrials Modernes show; out of these came the International Style and Art Deco.

The strong desire to harness nature's power drove the human mind and body to build a dam in the hottest, driest area of the United States. People wanting to irrigate low lying plains, known as low desert areas, without suffering from flooding and the battle over water made it obvious to the United States government that the Colorado River was part of the solution. (Right photo shows explosions preparing for construction.) Geologists and Hydrologists who surveyed to determine the best area to dam the mighty Colorado River waters initially determined that Boulder Canyon was going to be the site for the dam.
