Dam Impacts on Fishery Resources, Part 1

Monday, August 18, 2014: 1:30 PM-5:20 PM
202 (Centre des congrès de Québec // Québec City Convention Centre)
The effects of dams on fishery resources have been studied and debated for years.  Dams can provide water for irrigation, domestic and industrial use, hydropower generation, and control flooding.  They also modify river channels and natural flows, resulting in water quality changes, loss of migratory routes for diadromous fishes, and loss of land use for local owners.  Recent news stories on both dam removals (e.g., Elwha River, Penobscot River) and construction (e.g., Yangtze River in China), and the decision making surrounding those efforts have led to more open debate on the need for dams.  The objective of the symposium is to provide data documenting  the effects of both construction of new dams and dam removals on fishery resources, including social and environmental impacts.  We plan to provide a well-rounded holistic symposium, global in scope, to help assess the various concerns with dams including biological, social, and economic impacts, and to foster a greater appreciation for the many factors  surrounding dam construction and removal.
