The Colorado River '4-panel plot'

Variability and long-term trends in Colorado River Basin (Powell + Mead) reservoir storage (1935-2023), and in Upper Basin natural streamflow, precipitation, and temperature (1906-2023). This plot first appeared as Figure 2 in Udall and Overpeck (2017), "The twenty-first century Colorado River hot drought and implications for the future." Brad Udall has updated it annually.
