Use this page to explore the different datasets we have on offer. We have some of the world's most extensive data on transboundary freshwater governance, including spatial datasets and tabular datasets relating to water events and institutions in water governance. We also have a database of U.S. interstate freshwater compacts and a collection of basin-level datasets for watersheds in Oregon.
Access the TFDD Explorer, an interactive tool to explore physical and institutional data on the world's international river basins, groundwaters, and wetlands. The tool contains qualitative and tabular data on treaties (including full-text downloads), river basin organizations, and conflict-cooperation events. Also available on the TFDD Explorer are data on population, water consumption, water withdrawal, runoff, climate classifications, and existing and planned dams. The TFDD Explorer was made possible by the invaluable support of GWP, IUCN, Global Environment Facility (GEF)/IW-Learn, World Bank, Fine Family Faculty Fellowship, the Institute for Water and Watersheds, Institute of Natural Resources, and the Valley Library at Oregon State University.
International River Basin Register
Spatial Datasets
A register of the most current delineation of the world’s 310 international river basins, mapped by continent and basin country unit (the part of a basin that lies within one country). Regional maps and a downloadable excel file of spatial statistics for each basin are available in the 2018 Register of International River Basins.
Transboundary Freshwater Spatial Database
Spatial Datasets
Biophysical, socioeconomic, and geopolitical data relating to the world's international river basins are accessible and searchable through spatial and tabular formats. Shapefiles are available for the river basin delineation from 2014, 2016, and 2018, through interactive interfaces or for download.
International Freshwater Treaties Database
International Tabular Datasets
A searchable database of over 600 international, freshwater-related agreements, covering the years 1820 to 2007. The 2023 update to the database is currently being processed.
International Water Event Database
International Tabular Datasets
A searchable database documenting historical international water relations from 1948 to 2008.
International River Basin Organization (RBO) Database
International Tabular Datasets
A database of the currently known international river basin organizations coded by basin and countries involved, including level and type of collaboration, principal issue(s), date of creation, a short description of the organization and the source.
Transboundary Wetlands Database
International Tabular Datasets
A database of more than 300 transboundary wetlands. The database includes information on Ramsar designation, situatedness within international river basins, and presence of a river basin organization (RBO).
Regional Water Governance Benchmarking Project (ReWaB)
International Tabular Datasets
A study of water governance capacity in five Middle East North Africa Region (MENA) countries: Egypt, Jordan, Morocco, Turkey, and Oman, including a collection of searchable legal and policy documents from each country, as well as records from workshops held in the MENA region.
U.S. Interstate Freshwater Compacts Database
United States Tabular Datasets
A searchable database of 39 U.S. inter-state freshwater compacts, coded by the basin(s) and states involved, date signed, topic, allocation measures, conflict resolution mechanisms, and non-water linkages.
Collection of Research and Datasets on the Colorado River Basin
United States Tabular Datasets
Research and data collected by then-OSU student Nathan Eidem on the Upper Colorado River Basin for his PhD dissertation. Includes a searchable database of events in the regions from 1970-2005.
Collection of Research and Datasets on the Columbia River
United States Tabular Datasets
Research and data collected on the Columbia River Basin from projects completed 2010 to the present. Includes collaboration with the Universities Consortium on Columbia River Governance, the film A River Loved, and several Master's and PhD research by OSU graduates.
United States Tabular Datasets
A set of data and research complied between 1990-2004 to gain an understanding of water resources in Oregon that compares hydrologic data, demographic data and hydro-political data.
