Water Resource Management Challenges in a Time of Changing Climate

Water is scarce relative to demand in Arizona and the Colorado River Basin. Despite 14 years of drought, the likes of which have not been seen for over 900 years, Arizona is not in a crisis. However, central Arizona is particularly vulnerable to Colorado River shortage declaration due to the lower priority of Colorado River water delivered through the Central Arizona Project (CAP). While climate change is projected to impact water supplies and influence water demands, water decision makers must take actions to meet future demands, regardless of the cause of any shortfalls. A suite of policy options is presented, along with a recommendation for engagement of both expert stakeholders and the general public.
