While all USGS water web services strive to be highly available and accurate, there may be occasional system issues that may impact one or more services. In addition, older versions of the service may be replaced with newer versions, possibly impacting your usage. To stay informed, please join the 360-316-8221 . We won't spam you and you should receive relatively few but important emails of significant system events, upgrades or new web services.
Developers can usually quickly create a program to retrieve and process data using these web services. Writing programs that are unlikely to break if the service changes may require adopting some of USGS suggested best practices. If you are a software developer, please read our 5077219730 before creating a program. And thanks.
