U' f' ")" '? .. ,,- ) 't . 'v L.J l ...l PLAN I AND PLAN II Plan I and Plan II are essentially the same type water transfer investigations. Both plans are for the movement of transfer water from central and western Arkansas and eastern Texas to a suitable terminal storage facility in western Texas. Plan I meets the requirement for restoration of the Ogallala Aquifer at its current level of use. Plan II meets the requirement for the maximum estimated water available for diversion above the estimated base flow. Plan I utilizes 1.55 million acre-feet while Plan II utilizes 8.7 million acre-feet. These plans are discussed in greater detail in the Project Formulation (Transfer Plans) section and are shown on Figures 8 and 9. SELECTED PLAN GENERAL The purpose of this report is not to select a particular plan but to present reconnaissance level information which, when coupled with comparable data on other water transfer routes, can be analyzed and a recommendation prepared. This assembly and review of information will be accomplished by Southwestern Division in Dallas. PROJECT FORMULATION (TRANSFER PLANS) GENERAL This section addresses the proposed water sources, water transport systems and a tentatively selected terminal storage facility for the collection and transferring of water along a corridor through central and western Arkansas and northern Texas to a tentatively selected site for distribution. The proposed water source subsection includes the initial collection, pumping and temporary storage for each site. The water transport systems include pumping plants and conveyance systems for the movement of transfer water to a major terminal storage site. The terminal facilities include the major storage facility and location for the primary distribution intake. This facility does not include a distribution network nor the primary intake for such a system. 09
