Figure 3.3

U.S. Geological Survey
Gregory J. McCabe

This figure appears in chapter 3 of the Impacts, Risks, and Adaptation in the United States: The Fourth National Climate Assessment, Volume II report.

The figure shows the Colorado River Basin historical water supply and use, along with projected water supply and demand. The figure illustrates a challenge faced by water managers in many U.S. locations—a potential imbalance between future supply and demand but with considerable long-term variability that is not well understood for the future. For the projections, the dark lines are the median values and the shading represents the 10th to 90th percentile range.
