User feedback
The NWISWeb Users Group (NWUG) collects,
evaluates, and prioritizes requests for
enhancements, bug fixes, and recommends
overall improvements to the NWIS Web
Interface.
NWUG represents all users and solicits any
suggestions or ideas that may help USGS
to improve dissemination of water data.
