  • Large-Scale Impacts of Hydroelectric Development

    Large-Scale Impacts of Hydroelectric Development

    27 Large-scale impacts of hydroelectric development D.M. Rosenberg,1 F. Berkes, R.A. Bodaly, R.E. Hecky, C.A. Kelly, and J.W.M. Rudd Abstract: The substantial size of some hydroelectric projects and the extensive total surface area covered by reservoirs globally require that research determining the impacts of these developments be done at ever-increasing spatial and temporal scales. As a consequence of this research, new views are emerging about the spatial extent and longevity of the environmental and social impacts of such developments. New findings challenge the notion of hydroelectric development as a benign alternative to other forms of power generation. This review examines the intertwined environmental and social effects of methylmercury bioaccumulation in the food web, emission of greenhouse gases from reservoirs, downstream effects of altered flows, and impacts on biodiversity, each of which operates at its own unique spatial and temporal scales. Methylmercury bioaccumulation occurs at the smallest spatial and temporal scales of the four impacts reviewed, whereas downstream effects usually occur at the largest scales. Greenhouse gas emissions, the newest surprise connected with large-scale hydroelectric development, are relatively short term but eventually may have important global-scale consequences. Limitation of biodiversity by hydroelectric development usually occurs at intermediate spatial and temporal scales. Knowledge developed from working at expanded spatial and temporal scales should be an important part of future decision making for large-scale hydroelectric development. Key words: hydroelectric development, large-scale, environmental impacts, social impacts. Résumé : La dimension considérable de certains projets hydroélectriques et les vastes surfaces totales globalement couvertes par les réservoirs nécessitent que la recherche menée pour déterminer les impacts de ces développements soit conduite à des échelles d’espace et de temps de plus en plus grandes.
  • Missouri River Gavins Point to Ponca State Park

    Missouri River Gavins Point to Ponca State Park

    MISSOURI RIVER GAVINS POINT TO PONCA STATE PARK Recommendation For Inclusion Under Section S(d) of the Wild and Scenic Rivers Act Department of the Interior Bureau of Outdoor Recreation AUGUST 1971 MISSOURI RIVER -- GAVINS POINT DAM TO PONCA STATE PARK I. INTRODUCTION Beginning at Three Forks, Montana, the Missouri River flows south­ easterly over 2,300 miles to join the Mississippi a few miles north of St. Louis, Missouri. It ranks as the second longest and, his­ torically, one of the most famous rivers in the United States. It was the primary route of Lewis and Clark on their epic journey of exploration. Long before the advent of transcontinental railways, it shared with the Oregon Trail and the Santa Fe Trail the distinc­ tion of being one of the three main thoroughfares to the Far West, witnessing a cavalcade of fur trappers, missionaries, gold miners, and pioneer settlers. But here, instead of covered wagons, convey­ ance was by pirogue, keelboat and steamboat. It was a wild and un­ predictable river that carried millions of pounds of freight. Waters of this mighty river that for centuries ran uncontrolled are now harnessed in the upper and middle reaches by a series of multi­ purpose dams and reservoirs. In its lower reaches, the Missouri has been further tamed by channelization. The net effect of man's endeavors has been improved flood control and navigation, increased hydroelectric power generation, irrigation water and creation of new opportunities for outdoor recreation. However~ these worthy projects have also eliminated most of the extraordinary aesthetic, historic and wildlife values associated with the river in its natural condition.
