<br />. <br /> <br />Task 3.05 <br /> <br />Define Water Right Classes <br /> <br />Objective: Define approximately 10 classes or divisions of the domain of water right administration <br />numbers, such that water rights within a class may be administered together in the model. Thus class <br />divisions should be selected judiciously to reduce error introduced by allocating water to a right under a <br />class-average administration number rather than the right's actual priority. <br /> <br />Approach: <br />l. Boyle: Use the DMI watright to generate a listing of net absolute water rights in a basin, Generate <br />a list of structures modeled in Phase II using the StateMod -xdl report or by reviewing the Phase II <br />direct diversion right C* .ddr) file. Use ArcView to generate a list of all structures tied to irrigated <br />lands and a list of structures to be aggregated and modeled in Phase Illa. Import these files to a <br />spreadsheet and generate a plot of the cumulative net decreed amounts vs. administration number <br />for: <br /> <br />. <br /> <br />. All Absolute Diversion Water Rights <br />. Phase II Modeled Diversion Rights <br />. Diversion Rights Associated with All Irrigated Lands <br />. Phase Illa Modeled Diversion Rights <br />. Create a single plot using a spreadsheet, showing the cumulative decreed amount vs. <br />administration number for these four data sets, <br />2. Boyle: Divide the water right administration number domain into approximately 10 classes, <br />considering the following criteria: <br />. priority ofkey calling rights <br />. common sources of protection <br />. generally equal distribution of the total decreed amount among classes <br />3, The Division office and the State team should be solicited by phone for input regarding the first two <br />criteria; the plots developed above will support decisions based on the third criterion. The STATE <br />will advise Boyle of any water rights of special interest to CWeB, which should delineate a water <br />right class <br />4. Boyle: Prepare a Draft Task Memorandum describing the process and results, The memo is <br />expected to be approximately 3 to 5 pages, including the cumulative water right plot. <br />5. Boyle: Make the Draft Task Memorandum available to the Division Engineer for his review. Hold <br />a meeting or teleconference with him to review the administration classes, For budgeting purposes, <br />assume that review will take place in a meeting in Denver, and will be combined with the same 4 <br />hour Division review meeting of Task 3.03; if circumstances require a meeting at the Division <br />Office this activity will be considered out of scope and impact the schedule. The State CRDSS <br />management team will also provide written comments on the draft task memo and resolve how to <br />handle Task 3,05 review comments from the Division Engineer which may conflict with State <br />CRDSS team's comments. The State will complete their review of the memo within one week of <br />receiving the Division Engineer's comments. Boyle will finalize the Task memo within a week of <br />receiving the State's comments. <br /> <br /> <br />Phase lIIa Scope of Services <br /> <br />1159 <br /> <br />A-25 <br /> <br />Jan 31,1997 <br />
