Part of the USGS Water Science for Schools site, this resource defines irrigation water use and includes several tables and maps showing water use by various irrigation systems, by state, by crop, and by percentage of fresh water available. Students and teachers can look at their state and see 1990 data for how much ground water and how much ground water and surface water is used for irrigation. Various irrigation systems are defined, described, and pictured, along with a discussion of their relative efficiencies. A Spanish translation is available.
