Annual Water Data Reports

Water Resources Data reports  were published annually for many decades for use by engineers, scientists, managers, educators, and the general public. These static archival products supplemented direct access to current and historical water data provided by the National Water Information System web interface (NWISWeb), the authoritative source for USGS water data.

Beginning with Water Year 2006 and ending with Water Year 2013, annual water data reports were made available as individual electronic Site Data Sheets for the entire Nation for retrieval, download, and localized printing on demand. Over that time, NWISWeb capabilities have become more comprehensive. Building on these capabilities, USGS has moved the Site Data Sheet functions into NWISWeb. As of 2014, NWISWeb now provides an on-demand, print-ready Water-Year Summary as an annual water-data product.

2014-present: Water Year Summaries

Each site's Water-Year Summary will be available on-demand as soon as the water-year data are reviewed and approved as final.

Pre-2005: Water Resource Data reports

From 1962 until 2005, reports were published by State as paper documents, although most reports since the mid-1990s are also available in electronic form through this web page. Reports prior to Water Year 1961 were published in occasional USGS Water-Supply Papers and other reports.
