<br />OOJ8<t8 <br /> <br />HOW MUCH WATER IS AVAILABLE <br />FOR COLORADO TO USE? <br /> <br />This depends ultimately on how the <br />compact issues are resolved, AND <br />The assumptions we make on how <br />much water is available, where its <br />diverted in the Upper Basin, AND <br />The basic assumptions on inflow to <br />Lake Powell, which is highly variable. <br /> <br />., <br /> <br />DIFFERENT SCENARIOS <br /> <br />1) Noah's estimate: <br />.5175 X (7,500,000 - 50,000) = 3,858,000 at <br /> <br />2) Reclamation's hydrologic determination: <br />· Based on the 1954-1965 hydrology <br />(Reclamation assumes a 12.18 mat average <br />inflow to Lake Powell) <br />· Assumes a Lee Ferry delivery of 8.25 <br />mat/annum (7.5 mat for the Lower Basin plus <br />750k for Mexico). <br />.5175 X (6,000,000 - 50,000) = 3,079,000 at <br /> <br />3) The 1965 hydrology with no deliveries from Upper <br />Basin to Mexico - approximately 3,450,000 at. <br /> <br />9 <br />
