    • Crosswalk table between selected Conterminous United States (CONUS) Global Reservoir and Dam Database (GRanD) site and High-Value National Hydrographic Datasets

    Metadata Updated: October 30, 2025

    This data release provides coupling of Conterminous United States and several Canadian operational reservoirs used in recent hydrologic modeling studies to authoritative national hydrographic datasets used to identify, calibrate, model, and assess streamflow, water quantity, quality, and ecological resources. The National Inventory of Dams (NID) provides linkages to dams operated in the United States, GRanD provides linkages to Global Dams and Reservoirs, and the National Hydrography Dataset Plus (NHDPlus) provides linkages to the stream network and waterbodies to easily couple with National Hydrologic Models and landscape parameters. The Geospatial Fabric for National Hydrologic Modeling, version 1.1 (GFv1.1) provides linkages to existing National Hydrologic Model (NHM) spatial modeling units. All crosswalks, linkages, and other information is provided in a comma-separated value (csv) file.
