<br />1048 <br /> <br />ongoing basis, advise Boyle on State's preferences for handling special return flows <br />involving subjective or judgement calls <br />2. Boyle: For each aggregated structure, select a return flow node based on inspection of the <br />maps produced in Task 3.02, In most cases, the next downstream node will receive all <br />return flows; however, there may be cases in which flow enters the stream further <br />downstream or at more than one site. It is anticipated that these special cases will represent <br />approximately 10 percent of the new aggregated structures. <br />3. Boyle: Manually edit the Phase II .rtn file to include special cases of return flow timing and <br />location. <br />4. Boyle: Prepare a Task Memorandum summarizing how all special cases for return flow are <br />represented in the model. The State will provide written comments on the draft of this <br />memo within 2 weeks. The memo will be approximately 3 pages or less in length, <br /> <br />Deliverables: <br />1. Selected return flow patterns for aggregated structures. <br />2, Selected return flow locations for aggregated Structures. <br />3, Statemod input files to reflect aggregated structure return flows, <br />4. Task Memorandum 3.06, summarizing the results of this subtask. <br /> <br />Subtask 3.07 Generate Aggregated Parameters <br /> <br />Objective: For each aggregated node, calculate total or representative values for these structure <br />attributes: administration number, ditch capacity, and irrigated acreage served, Create <br />Statemod ,ddr and interim .dds files that include the aggregated irrigation structures. <br /> <br />Prerequisite: A Watright enhancement will be available to determine aggregated parameters for the <br />aggregated structures and rights. These parameters include combined ditch capacity <br />and flow-weighted administration number. Watright will generate a repon listing the <br />original structures and water rights by aggregation grouping, and the total ditch <br />capacity, weighted administration number, and total irrigated acreage for each <br />grouping. It will also create ,dds and ,ddr files. <br /> <br />Approach: <br />L Boyle: Execute Watright as described under "Prerequisites", <br />2, Boyle~ Prepare a brief Task Memorandum consisting primarily of the repon created by <br />Watright under Task 3,07.1 <br /> <br />Deliverables: <br />L Watright output of flow weighted administration numbers and other parameters for the <br />aggregated structures" <br />2. Task Memorandum showing administration number, ditch capacity, and irrigated acreage <br />served for each aggregated irrigation right to be operated in the modeL <br /> <br />Phase Ill.
