In the Western United States, the right to use water is called prior appropriation, which means "first in time, first in right." This means that whatever lien in land records was first, that lien holder has a higher priority to access water from the Colorado River, especially during times of insufficient water supply. Using the Fixes that Fail archetype, describe the variables and problems of accessing a limited water supply and the impacts this has on all lien holders in the river basin. Where are possible leverage points in this archetype? What are future options for those who use water for irrigation? How does population growth in the southwestern U.S., where water access is limited, impact systems thinking?
