The Lawrence Livermore National Laboratory, under the direction of the U.S. Department of Energy and using data from the U.S. Geological Survey, has produced flow charts showing the major sources and uses of water in every U.S. state in the year 2005.

The water sources are divided into ground vs. surface water and fresh vs. saline. Water flows from the sources (left), through the various uses (middle) and to their ultimate sinks (right), either being consumed, evaporated to the atmosphere, or discharged to surface waters or the ocean. The thickness of each line is proportional to the amount of water. In addition to flow charts for each state, an overall flow chart for the United States is also available.
