ABSTRACT
The southwestern United States experiences currently what is said to be the worst drought in 500 years (Ingram, 2015). In July 2015 nearly 80% of the region has been classified as under moderate to exceptional drought conditions (National Drought Mitigation Center, 2015), threatening water supply in the state of California. While there are uncertainties about the exact amounts and the time frame of occurrence, supply and demand studies agree that new water supply options need to be developed in the future to meet increasing demand and mitigate the impact of climate change in the Colorado River basin (ADWR, 2014, USBR, 2012, WRDC, 2011).
