Colorado River Risk Study Preliminary conclusions.
1. Under current conditions and operating policies, the likelihood of reaching critical elevations or a compact deficit is low, but impacts could be significant
2. Hydrology and amount of future growth in the Upper Basin are key drivers of risk
3. It is not just a Lower Basin or “Structural Deficit” problem, there are important steps to consider in the Upper Basin (hence there is an Upper Basin Drought Contingency Plan, see above)
