Reservoir storage "teacup" diagrams for U.S. Bureau of Reclamation (USBR) dams in the Pacific Northwest region. USBR provides average daily streamflows and reservoir storage levels for several river basins.

Reservoir data comes from the USBR's Hyrdomet, a network of automated hydrologic and meteorologic monitoring stations located throughout the Pacific Northwest, as well as their associated communications and computer systems.
