Description of the Data
Through the Global Water System Project (GWSP), an international team of scientists have spent 4 years collecting dam and reservoir data sets to address the need for global data describing their characteristics and geographical distribution. The goal of providing a single, geographically explicit and reliable database has resulted in the release of the Global Reservoir and Dam Database (GRanD).
Methods
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).
