<br />12/19/73 <br />JWN <br /> <br />ASSIGNMENT FOR THE WATER SUPPLY GROUP <br /> <br />Elmo McClendon, Corps, Group Leader <br />Phil Gibbs, Interior <br /> <br />1. What are the total depletions since 1949 above Gavins Point on the <br />Missouri River main stem reservoir system for the current (1970) <br />conditions of water use? <br /> <br />2. What is the approximate river mile location (map & table) of these <br />depletions by major categories of water use? <br /> <br />3, Under current (1970) conditions of water use, what remaining water <br />supplies are available for various uses by regulation of the main <br />stem reservoir system? <br /> <br />4. Present the most likely and the likely maximum and likely minimum <br />rates of growth of future depletions and the breakdown of these <br />depletions by major categories of water use and by geographic distri- <br />bution. (Identity criteria and assumptions use) <br /> <br />5. Compare the depletion rates determined in item 4 with those from <br />previous studies. (List previous studies) <br /> <br />6. Utilizing the three depletion rates from item 4, conduct long-term <br />(1898 to date) reservoir regulation studies for the main stem reservoir <br />system for the 1980, 2000, and 2020 development levels to demonstrate <br />the availability of water to meet the expected requirements and to <br />display the effects of the depletions on service to all functions, <br /> <br />7. Would the provision of water for M&I purposes in the quantities <br />indicated require storage regulation by the main stem reservoirs or <br />will sufficient flows be availablefor this purpose from river flows <br />alone in the reaches between reservoirs? <br />
