Water Quality

North Dakota Water Quality Data 

National Water Quality Data

  • National Water-Quality Assessment
    • The NAWQA data warehouse includes chemical concentrations in water, bed sediment, and aquatic organism tissues.
  • National Stream Quality Accounting
    • The NASQAN program provides ongoing characterization of the concentrations and flux of sediment and chemicals in the Nation's largest rivers.
  • Sediment Data Network
    • More than 2.6-million values of instantaneous sediment and ancillary data were retrieved for more than 15,000 sites in 2000 and summarized in an online report. Access is also provided to daily sediment data collected by USGS throughout the Nation from 1930 to 1994.


Surface Water

North Dakota Surface Water Data

National Suface Water Data

  • The USGS has a distributed water database that is locally managed. Surface-water, ground-water, and water-quality data are rolled up from these local, distributed databases into a national information system. The database contains records from about 50,000 surface-water sites and 850,000 wells that have been compiled during the course of hydrologic studies over the past 100 years, including over 4.4 million water-quality analyses. Data are served via the Internet through NWISWeb, the National Water Information System Web Interface. NWISWeb provides all USGS water data that are approved for public release. This large number of sites is excellent for some uses, but complicates retrivals when the user is interested in specific networks or applications. Several specialized products are available to supplement data provided through NWISWeb and to facilitate data discovery.


Ground Water

North Dakota Ground Water Data

National Ground Water Data

  • Active Water-Level Network
    • The Active Ground-Water Level Network contains water levels and well information from more than 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 365 days.
  • Climate Response Network
    • The USGS maintains a network of wells to monitor the effects of droughts and other climate variability on ground-water levels.
  • Real-Time Ground-Water Level Network
    • The Real Time Ground-Water Level Network contains water levels and well information from about 1,000 wells that have "real time" instrumentation at the well. Real-time ground-water data are continuous data that are transmitted from the well to the USGS by satellite or telephone at least once per day.
