Marmot Dam - Dams (sitios de interés)
Descripción del sitio
Removal of this 30 ft. high dam took place from 2007-2008. Prior to that this the Marmot Dam, located in the Sandy River Basin, provided hydro-generated power for some of the Portland area. The project was selected to be removed due to rising environmental costs. In addition, the negative impact on fish species and the release of 1 million cubic yards (750,000 cubic meters) of sediment into the river helped support the decision to remove the dam.
