WATER SCIENCE SPECIALTIES

WATER SCIENCE BY STATE

USGS Water Science Centers are located in each state

Water Resources Programs

Local Water Resources Offices — State and Regional

The USGS manages water information at offices located throughout the United States. Although all offices are tied together through a nationwide computer network, each collects data and conducts studies in a particular area. Local information is best found at these sites.

USGS Programs Managed by the Water Resources Discipline

  • Cooperative Water Program
    Conducts data collection and investigations that form the foundation for water-resources management and planning activities nationwide, through partnerships with over 1,000 State and local agencies.
  • National Streamflow Information Program (NSIP)
    Implements the USGS plan to ensure reliable and consistent acquisition and delivery of streamflow information at key sites.
  • National Water-Quality Assessment Program (NAWQA)
    Provides an understanding of water-quality of the Nation's surface water and groundwater and how those conditions may vary locally, regionally, and nationally; whether conditions are getting better or worse over time; and how water quality is affected by natural features and human activities.
  • Groundwater Resources Program
    Provides research and information for groundwater sustainability and ties to human and environmental needs.
  • Hydrologic Research and Development
    Conducts basic and problem-oriented research into varied and complex hydrologic processes that are not well understood.
  • State Water Resources Research Institute Program
    Supports water resources research, education, and information transfer at the 54 university-based State Water Resources Research Institutes, through the use of matching grants.
  • Hydrologic Networks and Analysis (HNA)
    Includes the Federal core of the USGS water-quality networks, a variety of research and investigations, and a portion of USGS information storage, coordination, and dissemination efforts, including the National Water Information System.

Sub-Programs

Initiatives

  • National Water Census
    An initiative to provide a nationwide assessment of water availability and use. Information will be provided on components of the water budget, on water use, and ecological flow estimation. Regional Groundwater Studies will be expanded.
