1. O'Shaughnessy Dam - Better known as Hetch Hetchy Dam. Currently numbers of environmental groups have proposals targeting the removal of this dam, the biggest deterrent would be cost of the project. If the dam is removed people are hoping the valley would slowly return to the way it looked around 1900.
