Join the USGS Water Data for the Nation community for a public webinar on Thursday April 11th at 2 pm ET / 12 pm MT to hear an overview of changes to data access and a Q&A session. New features include Observed Properties which is a modernized and standardized parameter description.

In conjunction with the modernization of USGS’s storage and management system for discrete data, the public delivery of USGS samples and water quality data has been modernized. Changes are live as of April 2, 2024.

On April 2, the transition from legacy to modernized systems was successfully completed. All USGS samples and discrete water quality (WQ) data (data collected in separate and distinct events through trips to water quality field locations) is now available through new Water Data For the Nation (WDFN) endpoints. New WDFN pages and features provide access to all discrete water-quality and samples data and information. These pages allow users to find, filter, and download samples data. Read an overview of the new features, including images and links to new pages.

On March 11, 2024, updates to samples data available through the legacy NWISWeb QW system were paused. Going forward, no new data will be available through the legacy system and legacy QW data will be decommissioned later this calendar year.
