Data, 13, 213–229, https://doi.org/10.5194/essd-13-213-2021, 2021. Updated version 1.0.2: We present version 1.0.2 to the DDSA database, the improvements made to version 1.0.1 are described below: Supplementary table 1: Future Dams in South America has been updated and now 574 future projected dams in South America, 61 under construction for 2020 and 513 planned projects for the future. Updates made in version 1.0.1: Version 1.0.1 to the DDSA database, includes improvements made to version 1.0.0, which are described below: New hydrological information attributes have been included: Aridity index Residence time Degree of regulation. A shapefile of watersheds for each dam has been included. Supplementary table 1: Future Dams in South America has been included. Use of the dataset Before using the dataset, please notify us (be.paredes@alumnos.upm.es; be.paredes@uta.edu.ec) if you use the dataset so that we can keep track of how it is used and take that into consideration when updating and improving the dataset. When using this dataset or one of its updates, please cite the DOI of the precise version of the dataset used and also the data description article which this dataset is supplement to (see above).

In general, its relevance relies on facilitating the management of water resources for anthropogenic purposes. However, dams could also generate many potential adverse impacts related to safety, ecology or biodiversity. These factors, and the additional effects that climate change could cause in these infrastructures and their surrounding environment, highlight the importance of dams and the necessity for their continuous monitoring and study. There are several studies examining dams both at regional and global scale, however, those that include the South America region focus mainly on the most renowned basins (primarily the Amazon basin), most likely due to the lack of records on the rest of the basins of the region. For this reason, a consistent database of georeferenced dams located in South America is presented: Dataset of georeferenced dams in South America DDSA. It contains 1,010 entries of dams with a combined reservoir volume of 1,017
