<br />.,~QO~2~2 <br />.' <br /> <br />Scope of Work <br />2a.1 Assist CWCB staff (Andy Moore) in their review of the fall, winter and springtime release <br />operation of the 16 reservoirs in the "Calculated" and "Historic" scenario" for the Colorado <br />River Basin in light of recommendations to change that operation made by USBR and <br />Denver. It is assumed that any recommendations to change reservoir release patterns will be <br />available to CWCB staff prior to initialization of this review. <br />2a2 Based on the CWCB review of modeled reservoir operations, USBR recommendations as <br />presented in the CWCB meeting minutes, Southeast Water Conservation District comments <br />on the USBR suggested reservoir operations and the 1997 Annual Operating Plan for the <br />Colorado Big Thompson Project and Western Power System Operations, prepare written <br />recommendations of a modeling strategy for releases from the 16 major Colorado River <br />reservOIrs. <br />2a,3 In a 4 hour meeting with CRDSS management and/or CWCB staff, review and finalize <br />changes to be made to the modeled operation of each of the 16 major reservoirs. <br />2a.4 Modify the model's input data (in the base model data directories on cando)to reflect the <br />agreed on operating rules. It is anticipated that modifications to the statemod program would <br />not be necessary by Mr. Bethel and that changes would only be made to the "Calculated" <br />scenario input data for the model. Rerun the Calculated scenario. Note: It is expected that <br />modifications to the statemod model will be made by Mr. Bennett to allow the imposition of <br />targets on individual storage accounts. <br />2a.5 In draft form, modifY (redline) existing Phase II documentation to reflect changes in <br />methodology, assumptions and results resulting from this task. This subtask will not involve <br />re-calibration of the model since it is generally the calculated rather than the historic scenario <br />that is being adjusted. <br />2a.6 After receiving CRDSS/CWCB comments of the draft task documentation, finalize the <br />modifications to the Phase II documentation to present the results of this task. <br /> <br />Deliverables (referencing subtask identifiers): <br />2al&2a2 A memo (5-6 pages) that describes the current (Phase II) operation of the 16 <br />reservoirs, the USBR recommendations and a recommended modeling strategy. The <br />intent of this memo is to serve as a discussion foundation for finalization of modeling <br />strategies with the CRDSS management. <br />2a3&2a4 Modified "calculated" scenario input data for the 16 reservoirs in the Colorado River <br />Basin model reflecting changes agreed on with the CRDSS management team. <br />2a5&2a6 Draft and final versions of documentation of the subtask through modifications to the <br />Phase II documentation. <br /> <br />Cost Estimate: <br />Task 2al <br />Task 2a2 <br />Task 2a3 <br />Task 2a4 <br /> <br />8 hours @ $82/hr = $ 650 <br />8 hours @ $ 82/hr = $ 650 <br />4 hours @ $ 82/hr= $ 330 <br />12 hours @ $ 82/hr= $ 980 <br /> <br />2 <br />
