The Global Reservoir and Dam (GRanD) Database provides the location and main specifications of large global reservoirs and dams with a storage capacity of more than 0.1km³ both in point and polygon format. The current version 1.1 of GRanD contains 6,862 records of reservoirs with a cumulative storage capacity of 6,197km³ and their attribute data. The development of GRanD primarily aimed at compiling the available reservoir and dam information, correcting it through extensive cross-validation, error checking and identification of duplicate records, attribute conflicts or mismatches; and completing missing information from new sources or statistical approaches. The dams were geospatially referenced and assigned to polygons depicting reservoirs outlines at high spatial resolution.
