  • Narrative: In this EcoWest presentation, we share some graphics from a recent study of the Colorado River, which supplies drinking water to some 35 million people.
  • Narrative: This map shows the Colorado River watershed and also includes adjacent areas that receive water from the Colorado River, such as the Colorado Front Range and Southern California. Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: The flow of the Colorado River, shown in blue, varies greatly from year to year, but water use in the basin, shown in red, has been increasing fairly steadily. Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: This graphic also looks into the future and shows that water demands are likely to outstrip supplies.Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: Agriculture dominates water use in the Colorado River Basin, but municipal and industrial consumption has been growing. The system also loses a fair amount to evaporation.Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: Here’s another look at the data in which use is categorized by whether it was in the Upper or Lower Basin, Mexico, or lost to evaporation. Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: The Basin Study examined a number of options for meeting the shortfall. Here’s how the options were distributed.Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: This cost curve compares all of the options by their price, in dollars per acre-foot per year. The color coding categorizes the different options. Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: Here’s how the options compare in terms of their potential yield by 2035.Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: And in 2060.Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: This version combines cost and yield by varying the width of the lines according to how much water each option could deliver by 2060. Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
  • Narrative: This graphic compares the 2035 and 2060 yields of the various options. Source: Colorado River Basin Water Supply & Demand StudyURL: http://www.usbr.gov/lc/region/programs/crbstudy.htmlNotes:
