The CAGRD Water Supply Program (WSP) was created with a goal of ending CAGRD’s reliance on Excess CAP water, which has been achieved. The WSP has acquired sufficient water supplies to meet projected replenishment obligations for the next 30 years or longer. These water supplies (shown below) include CAP supplies, effluent, and long-term storage credits. The next challenge will be to firm up these existing supplies because more than half of the CAP water in the portfolio will be potentially subject to shortage when the water level of Lake Mead is below the elevation of 1,075 feet. In the current portfolio, CAGRD will be reliant on long-term storage credits to meet obligations when those CAP supplies are reduced by shortage. Acquisition of additional water supplies within the next 5 years will focus on firming of these existing supplies.
