Folder “CRD” contains the recorded (5,143) reservoirs from yearbook and document data and all (97,435) reservoirs from CRD (China Reservoir Database) two parts:

CRD_all_reservoirs (in both shapefile format and the comma-separated values (csv) format): This database catalogs the location information of 97,435 reservoirs in China, with an aggregated area of 50,085.21 km2 and an estimated total storage capacity of 979.62 Gt. The attributes of all the CRD reservoirs (in all cases) include location information (longitude, latitude, province, prefecture, and county), inundation area, and estimated storage capacity.

CRD_record_reservoirs (in both shapefile and csv): The 5,143 reservoirs in the CRD database were directly derived from the yearbook and other documents data, accounting for 59% and 82% of the total reservoir area and storage capacity of the CRD database, respectively. This reservoir information was mainly obtained through manual compilation. The attributes of the recorded reservoirs include the longitude and latitude of the reservoir, name, province, prefecture, and county where the reservoir is located, water area, normal water level, storage capacity, reservoir class, main use, and regulation type.
