<br />) <br /> <br />3.0 COMPUTER MODEL DEVELOPMENT <br /> <br />The Consultant will evaluate the City's water rights portfolio based on the rights' diversion records <br />(obtained in Task 1.0) and the provisions of the City's transfer decrees. This data will be correlated <br />with a similar evaluation which was completed in 1987 by City staff and its legal consultant. The <br />purpose of this evaluation is to establish the operational parameters and constraints which control <br />yields to the City. For all rights owned by the City but not yet transferred, it will be assumed that <br />transfer conditions consistent with recent transfer cases would apply. For future evaluations, where <br />the possibility exists that the City could purchase additional ownership, it will be assumed that the <br />additional yields of these rights would be subject to the conditions imposed in current transfer <br />decrees . <br /> <br />Other rights on South Boulder Creek in which the City currently has no ownership will also be <br />evaluated. The assumption will be made that yield from such rights to the City would be at a rate of <br />60% of pro rata entitlement, unless a different percentage is justified based upon recent transfer cases <br />for those rights. <br /> <br />Based upon the physical and operational system information provided by the City and the water rights <br />evaluation discussed above, the Consultant will develop a flowchart, depicting the monthly operation <br />of South Boulder Creek water rights, as it directly relates to the City's water supply system. This <br />flowchart will provide the basis for designing a computer model to simulate the diversion, <br />conveyance, storage, and delivery of all City water supplies to meet current and projected future <br />demands under the three selected scenarios. The flowchart will be submitted to the City for review <br />and comment. The Consultant will then finalize the flowchart for City approval prior to commencing <br />inodel development. <br /> <br />The Consultant will then develop a computer model according to the approved flowchart to operate <br />the City's portfolio of water rights. Simulation of the City's system will be based upol! historic yields <br />over the 1950-1985 period of record (or later, if information is available) and three sets of water <br />demands: 1m, ultimate, and interim. For this analysis it will be assumed that the future demand <br />hydrographs will parallel existing monthly City hydrographs. These operations will be conducted on <br /> <br />A-3 <br /> <br />196'l$.da_a.TXT <br />07\23\91 mJb <br />
