Other National Water Availability Assessment Products
The USGS National Water Availability Assessment consists of reports, which provide a scientific summary and interpretation of water quantity, quality and use, and the data companion, which delivers model-based estimates of water supply and demand.
The National Water Availability Assessment Data Companion provides online information about water availability, quality, and use of the Nation’s surface and groundwater. The information in the Data Companion covers past conditions over multiple decades, and eventually will include future projections over multiple decades. This centralized delivery of model and trend information complements the centralized delivery of observational data in USGS Water Data for the Nation (WDFN).
The Data Companion allows users to download data through webservices and APIs for use in their own models, map viewers, and other tools. The Data Companion also allows users to interactively visualize and explore data online an interactive mapper.
More information on current and future content and functionality is available on the NWDC’s About page.
