Water-resources data for North Dakota consists of records of discharge, stage, and water quality for streams; contents, stage, and water quality for lakes
and reservoirs; and water levels and water quality for ground-water wells.
Beginning with water year 2006, the Annual Water-Data Report has been changed to an online only system that makes surface-water, ground-water, and water-quality data available for the United States from one location. The new user interface allows users to search for data by state and county, hydrologic unit, and site number. There is also a map-based tool for locating hydrologic data. Click on the "Mapper" link to use the map tool.
A water year is the 12-month period October 1 through September 30. The water year is designated by the calendar year in which it ends and which includes 9 of the 12 months. Thus, the year ending September 30, 2005, is called the 2005 water year.
