Student Presentation: The Glen Canyon Dam by Robert and Eric

  1. 1. The Glen Canyon Dam<br />Robert B. <br />and<br />Eric K.<br />
  2. 2. Purpose of the dam<br /> The dam was built for typical reasons, such as providing hydroelectricity, controlling flooding, and serving as a reservoir for the surrounding communities. <br />
  3. 3. Engineering Challenges<br /> While the dam’s plans were originally supposed to mimic the plans of the hoover dam, the surrounding environment not the same, leading to some complications. The surrounding rock on which the dam was to be placed was weak sandstone, very vulnerable to breaking under the dam’s weight. To combat this issue, the engineers decided to increase the width of the dam in order to decrease the pressure put of the sandstone per square inch.<br />
  4. 4. Controversies <br /> The main group disturbed by the construction of the Glen Canyon Dam was the Navajo Native American Tribe. The Powell lake created as a result of the Dam covered up many of the tribe’s land, greatly affecting their culture. Religious sites they visited regularly were no longer available at the bottom of the lake.<br /> One monument, the Rainbow Bridge, has remained above the water after the dam’s construction. Originally visited by few outsiders of the Navajo<br />community, this natural feature is now a popular tourist<br />attraction.<br /> In the 1974 court case Badoni vs. Higginson, several<br />Navajo medicine men sued because the dam violated their <br />First Amendment rights (freedom of religion). They claimed that<br />the former valley included sacred sites that were drowned by<br />Lake Powell. Unfortunately, the medicine men lost because the<br />court favored the economic interests of the federal government.<br />
  5. 5. Benefits of the dam<br /> The many benefits of the dam are mainly the reasons the dam was built in the first place. With the dam around, there was control gained over the previously wild river, preventing dangerous floods. The dam also provided hydroelectric power, a water reservoir, and a place of recreational activity for the surrounding communities. <br />
  6. 6. Negative effects <br /> The negative effects of the dam are ones not exactly expected by the people of LA. The immediate effects were the loss of beautiful landscapes now underwater. After time, people noticed the decreasing populations of salmon in the lake, and the BPA started a huge $721 million program to save them, but the species still remains endangered.<br />
