• National Water Information System
  

  The United States Geological Survey has collected water-resources data at approximately 1.5 million sites across the United States, Puerto Rico, and Guam. Surface-water data, such as gage height (stage) and streamflow (discharge), are collected at major rivers, lakes, and reservoirs. Ground-water data, such as water level, are collected at wells and springs.

  Water-quality data are available for both surface water and ground water. Examples of water-quality data collected are temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds. This web site serves current and historical data. Data are retrieved by category of data, such as surface water, ground water, or water quality, and by geographic area.
