. . 6, 6. . A historical direct diversion demand file (*H.ddm) that includes aggregatea structures, . A calculated direct diversion demand file (*C.ddm) that includes aggregated structures, . A direct diversion station file (*.dds) file that incorporates basin wide efficiency values for aggregated structures and diversion capacities that reflect maximwn historical diversion estimates. Boyle: Task Memorandwn 3.09 containing approximately 7 pages of text describing this Task. Task 3.10 Aggregate Municipal and Industrial Use Objective: Aggregate municipal and industrial uses not explicitly modeled in Phase II to simulate their depletive effects in the basin. Asswnptions: The basis for estimating basin wide M&I use is the Phase II Consumptive Use model and the conswnptive use report for "Other Uses". M&I uses are modeled as depletions rather than diversions with return flows, The State will revise the StateMod CU report (*xcu) to include averages for each structure. Approach: I. STATE: Summarize the non-irrigation use in the Phase II model under the historical demand scenario using the StateMod consumptive use report (*.xcu) and M&I indicators such as no irrigated acreage or an M&I return pattern in the direct diversion station file (* .dds) 2. STATE: Obtain annual "other water use" reflected in the Conswnptive Use report, 3. STATE: Calculate the aggregated M&I use as the difference between the non-irrigation uses from the conswnptive use report and that modeled in Phase II. 4. STATE: Assign the aggregated M&I use to no more than 4 locations in the basin using engineering judgment. For budgeting purposes, assume aggregated M&I use will be distributed to no more than 4 locations evenly. 5, STATE: At a regularly scheduled progress meeting, brief Boyle team on spatial aggregation of aggregated M&I and incorporate their input as appropriate, before completing task, 6, STATE: Estimate monthly aggregated M&I demands to be annual data distributed over 12 months evenly. Using a spread sheet or editor, create a file of aggregated M&I demands in StateMod format for the study period for demandts in Step 3,09, Assign aggregated M&I structures a senior water right with a decree sufficient to satisfy their demand and an administration number to reflect their highest priority use status. This data will be incorporated into StateMod files as part of Task 3.07. 7, STATE: Review the model network file (*net) resulting from the DMI makenet in task 3.04 to reflect the aggregated M&I structures. 8, STATE: Prepare Task Memorandum 3,\0 containing approximately 3 pages of text describing the results ofthe previous steps. The memo will include the following: . Description of methods and result of the difference calculations between Phase II M&I demands and the Consumptive Use model for "Other Uses", . Location and amounts of aggregated M&I demands and their assigned water right and administration nwnber. 1154 Phase IIla Scope of Services A.30 Jan 31,1997
