(multimedia) Eric Evenson, coordinator of the National Water Census discuses a new set of water resource challenges brought on by the 21st century. Even in normal water years, water shortages and use conflicts have become commonplace in many areas of the United States — especially competition among crop irrigation, growing cities and communities, and energy production. Over the next 10 years, the USGS plans to conduct a new assessment of water availability and use. This national Water Census will address critical aspects of recent Federal legislation, including the need to establish a national water assessment program.
