There are over 75,000 large dams on rivers in the United States alone. The goal of this project is to measure the ecological ‘footprint' of these dams in watersheds across the lower 48 states in the U.S. This Working Group will define this footprint in terms of the effect dams have had on:
- Water quantity and quality
- Number of native and non-native species in rivers
- Salinity of soils in productive agricultural areas
- Demand for irrigated water by the 100 largest cities in the U.S
Additionally, this Working Group will use information from global climate change models, and other models that describe how water moves across landscapes to develop sustainable solutions to water shortages that consider water for cities, farms and biodiversity conservation.
The research will prepare the Working Group for a final workshop in which noted popular press authors and policy makers are invited to write an opinion piece for The New York Times. This article will comment on the state of U.S. freshwater infrastructure (based on this scientific work), and propose a policy platform for freshwater sustainability in the U.S.
