The Global Reservoir and Dam Database, Version 1 (GRanDv1), Revision 01 contains 6,862 records of reservoirs and their associated dams with a cumulative storage capacity of 6,197 cubic km. The dams were geospatially referenced and assigned to polygons depicting reservoir outlines at high spatial resolution. Dams and reservoirs have multiple attributes, such as primary use, nearest city, area, name of impounded river, year of construction (or commissioning). While the main focus was to include all reservoirs with a storage capacity of more than 0.1 km3, many smaller reservoirs were added if data were available. Technical documentation describing the development of GRanD is available (download PDF).
SEDAC would like to acknowledge Dr. Bernhard Lehner and colleagues for providing these data for distribution.
