United States Environmental Protection Agency. The Office of Ground Water and Drinking Water (OGWDW), together with states, tribes, and its many partners, protects public health by ensuring safe drinking water and protecting ground water. OGWDW, along with EPA's ten regional drinking water programs, oversees implementation of the Safe Drinking Water Act, which is the national law safeguarding tap water in America.

The program focuses not just on improving water quality in an estuary, but on maintaining the integrity of the whole system. The NEP is a collaborative, efficient, and adaptable ecosystem-based network of organizations that protects and restores 28 estuaries of national significance. U.S. Environmental Protection Agency

Universities and Organizations Leading in Education, Research and Public Service in Water Resources. The Universities Council on Water Resources (UCOWR) was founded in 1964 as an expansion of the Universities Council on Hydrology. UCOWR is an association of universities and organizations leading in education, research, and public service in water resources. UCOWR members and delegates are at the forefront of water resources related research and education, and represent various fields of natural and social science.

Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. The USGS works with partners to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.

Daily Streamflow Conditions. Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival.

Maps and graphs of current water resources conditions in the U.S. WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis. WaterWatch provides streamgage-based maps that show the location of more than 3,000 long-term (30 years or more) USGS streamgages; use colors to represent streamflow conditions compared to historical streamflow; feature a point-and-click interface allowing users to retrieve graphs of stream stage (water elevation) and flow; and highlight locations where extreme hydrologic events, such as floods and droughts, are occurring.
