VI. White River near State Line vii. Green River above Yampa River (added from those in SWSI) Summaries (graphical and tabular) of maximum. mean. median. and minimum stream flows and upstream depletions will be prepared at these locations for monthly and mmual time steps. Summaries will also be prepared for drought sequences in the 1930s and 1950s. 8. Colorado River Comnact Own-jew/Analvses a. Review and summarize (in a task memo) key legal and operating procedures that may be relevant to the study and interpretation of the study findings. Key documents include: i. Colorado River Compact ii. Upper Colorado River Compact iii. Coordinated Long-Range Operating Criteria & Interim SUl1Jlus Guidelines or in the alternative when completed the Lower Basin shortage Guidelines and the Coordinated Operation of Lakes Powell and Mead IV. Mexican Treaty v. SWSI Compact Review Yl. CWCB Investigations (including 1995 anlaysis of water available to Colorado under Compact). VII. Tipton and Kalmbach Vll1. SCS Basin Studies IX. USBR Basinwide Planning Reports. Consumptive Uses and Losses Report x. Upper Colorado River Commission Colorado River Compact Analyses xi. Eric Kuhn Analysis b. Following above review/analysis and in consultation with State legal representatives, prepare and document reasonable ranges for Colorado's Colorado River allowable depletions and the associated required (for the Compacts) streamflow leaving the State. Also document reasonable ranges of values during several ~rought cycles (1930s and 1950st ~ _ ~ _ ~ _ _ _ _- c. ~repare a workshop for any Roundtable members who wish to learn more about the Colorado River compact issues and comment on the strategy proposed to be employed in this study. t _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ __ d. Prepare comparative tables (such as Figure 7-4 below from the SWSI report below) and figures of estimates of allowable depletions (and required streamflow. if appropriate) from various sources. the range of these values developed from this study and how those values and ranges compare to the simulated depletions and streamflows (leaving the state) from the current supply/uses scenario developed in Tasks 3 through 6 above. e. Prepare a memorandum, for distribution to Roundable members, summarizing the methodology. assumptions and results of the comparative analyses of "Colorado's remaining Compact Entitlements". Colorado River Water A \'ailability Study Scope 6 June 25. 2007 Draft Comment: Could we and does it make sense to include the drought centered on 2002? - Comment: I think this is a very \vise idea and suggest breaking it out as a separate task. Perhaps we could hold more than one \vorkshop and our intert~1ce \vith the roundtables could be through documents, \vorkshops, and the IEee rather than visiting each roundtable.
