Data Center Description
The National Water Information System (NWIS) is a new system that was based on
the effort/development from several other USGS water related web systems: the
national system for historic stream flow data (NWIS-W), and the real-time
stream flow data system; and several development efforts that were established
in our districts.

The goal of NWIS Web is to provide both internal and external users of USGS
water information with an easy to use, geographically seamless interface. The
NWIS site updates its data on a regularly scheduled basis.
