Annual Water-Data Reports
Water-resources data are published annually by the U.S. Geological Survey for use by engineers, scientists, managers, educators, and the general public. Beginning with water year 2006, the annual Water-Data Reports have been published as individual electronic Site Data Sheets in PDF format.
Reports for water years prior to 2006 are available from the Publications Warehouse. For water years 1971 to 2005, the annual Water-Data Reports were published on a state-boundary basis. Prior to 1971, water-resources data were published in a series of Water-Supply Papers and in other reports.
