Description:

The Global Reservoir and Dam Database (GRanD) v1.1 is a product of the Global Water System Project, which initiated a collaborative international effort to collate existing dam and reservoir datasets with the aim of providing a single, geographically explicit and reliable database for the scientific community.
The initial version 1.1 of GRanD contains 6,862 records of reservoirs and their associated dams with a cumulative storage capacity of 6,197 km3. Data was assembled from numerous sources by eleven participating institutions, and the dataset is managed by McGill University. Though GRanD has undergone an update, GRanD v1.1 will remain available to support existing and future research.
GRanD v1.3 augments v1.1 with an additional 458 reservoirs and associated dams to bring the total number of records to 7320. Most of the added reservoirs were constructed between 2000 and 2016; global reservoir storage is increased by 666.5 km3. Updates have also been made to attribute data originally developed for GRanD v1.1; this includes a new column to indicate whether and when a dam has been removed. Access the data from our directory page ( https://www.globaldamwatch.org/directory ) .
