Global Dam Watch is an international collaboration between an expanding group of researchers who are passionate about understanding the costs and benefits of dams to our world

We bring together information about where to find the world’s most comprehensive dam datasets, currently comprising more than 200,000 georeferenced records, and we offer our own curated global compilations.

Global Dam Watch’s central mission is to work across disciplines and scales to gather and share high quality, georeferenced regional and global dam data. Care to participate? Reach out using the form on our Contact page.

Global Dam Watch’s Core Datasets

Our initial core datasets have driven hundreds of peer-reviewed studies, and we are in the process of harmonizing the three datasets to increase their utility.

Stay up to date on our efforts.

The Global Dam Watch team combines efforts to maintain up-to-date versions of established core datasets. The most comprehensive version of the dataset to date, the newly published GlObal geOreferenced Database of DamsGlobal Georeferenced Database of Dams contains more than 38,000 dams as well as their associated catchments.

The dataset enables new and improved global analyses of the impact of dams on society and the environment, and the impact that environmental changes—i.e. land use and climate change—may have on their catchments.
