Excess releases are defined as Mead releases in excess <br /> <br />of scheduled downstream demands. The excess releases are distributed <br />\~ <br /> <br />-~~ <br />~()/fV <br /> <br />equally to CAP and MWD. If one of these two users reaches its maximum <br />capacity, the other user may use the remaining excess release up to its <br /> <br />maximum capacity. Any remaining excess releases are given to Mexico. <br /> <br />Surplus deliveries to CAP and MWD are not scheduled in the base case. <br />This is the major concept that makes the alternative operating strategies <br /> <br />different than the base case strategy. By predicting excess releases and <br /> <br />scheduling the excess as surplus deliveries over a period of time, the <br /> <br />excess water can be used more beneficially for making deliveries, <br /> <br />gene rat i ng <br /> <br />power, and reducing flood damage.
