Users can choose to download or order six posters that depict water-resources topics and are drawn in a cartoon format. Written narrative on the back elaborates on the topic of each poster. They are available in color, or in black-and-white for coloring. Full description.

This resource discusses the distribution of water on Earth's surface, in soil moisture and groundwater, and in the atmosphere. Charts and graphs summarize total water withdrawals from surface and ground sources, and provide an estimate of global water distribution, in cubic miles and cubic kilometers, from all known sources. Links to additional information are embedded in the text. Full description.

This set of summary data tables shows information about water use in the United States, by state. Categories include total water use, public use, domestic use, irrigation, industrial, mining, and livestock uses. There is also a table showing thermoelectric power withdrawals. All information is for the year 2000. Full description.

This interactive map allows users to find their local watersheds and access a variety of information on conditions in them. Search hierarchy is based on region (the largest), subregion, accounting unit, and hydrologic unit (the smallest). The information includes streamflow data (real-time and archived), water quality data, water use data, groundwater sites by county, and links to regional studies ... Full description.

This summary data table shows the total land area of each state, the area covered by water, and the percent of total area that is covered by water. The data represents only inland water, that is, surface water bodies surrounded by lands of the United States. Areas such as the Great Lakes are excluded. Full description.

This resource provides an overview of the distribution and occurence of water on Earth. Topics include where and how much water there is, the water cycle, and how water is measured. There is also discussion of characteristics and distribution of surface water, groundwater, glaciers, and icecaps. Full description.

This portal provides access to a large selection of real-time and archived data on stream flow and water quality for surface and groundwater. Links are provided to the National Water Information System Web Interface (NWISWeb), which accesses data collected at approximately 1.5 million sites in all 50 states, the District of Columbia, and Puerto Rico. Data categories include current conditions information ... Full description.
