Major dams

The State of the World's Rivers is an interactive web database that illustrates data on ecological health in the world’s 50 major river basins. Indicators of ecosystem health are grouped into the categories of river fragmentation, biodiversity, and water quality. The database was created and published by International Rivers in 2014. The Dam Hotspots data contains over 5,000 dam locations determined by latitude and longitude coordinates. These locations were confined to the world’s 50 major river basins. The data set comes from multiple sources, and was corrected for location errors by International Rivers. The “project status”—a moving target—was determined by acquiring official government data, as well as through primary research from Berkeley and five International Rivers’ regional offices.* Operational: Already existing dams.* Under construction: Dams which are currently being constructed.* Planned: Dams whose studies or licensing have been completed, but construction has yet to begin.* Inventoried: Dams whose potential site has been selected, but neither studies nor licensing have occurred.* Suspended: Dams which have been temporarily or permanently suspended, deactivated, cancelled, or revoked.* Unknown: No data are currently available.
