National Water Availability Assessment Data Companion

The National Water Availability Assessment Data Companion (NWDC) delivers model-based estimates of water supply and demand.

When fully implemented, the National Water Availability Assessment Data Companion (NWDC) will provide regularly updated online information about water quantity, quality, and use of the Nation’s surface and groundwater. The information in the NWDC will cover past conditions over multiple decades as well as future projections over multiple decades. This centralized delivery of model and trend information will complement the centralized delivery of observational data in USGS Water Data for the Nation (WDFN).

Currently, the NWDC allows people outside USGS to use webservices and APIs to pull data and model predictions into their own models, map viewers, and other tools. In the future, the data companion will also allow users to interactively visualize and explore data online through mappers and dashboards.

More information on current and future content and functionality is available on the NWDC’s About page.
