<br />.1 <br /> <br />"l5. <br /> <br /> <br />1. STATE: IdentifY diversions in the Yampa River Basin which are tied to irrigated land but have no <br />location. Define locations for these headgates, Update the CROSS ArcInfo formatted file of <br />"Diversions" to include these structures. <br />2. STATE: ModifY StateMod to allow reports providing a list of structures (wdid) modeled in a given <br />simulation, Run this option with the Phase II Yampa River .dds file, <br />3. STATE: Define locations for all baseflow nodes contained in the Phase II Yampa River Basin <br />Model. prepare a location file for these suitable for import into an Arc View file. <br />4. STATE: Set up a project in Arc View (SGI version) with the following elements: <br />. River Basins (with Yampa River Basin differentiated by color from other basins) <br />. 500K hydrology <br />. Phase II modeled structures created above should be imported into the project file. <br />. Irrigated lands for the Yampa River Basin (showing only cropland (types 1-9) with <br />irrigation flag), The irrigated land table should be joined to table of Phase II modeled <br />irrigation structures, and used to color differentiate Phase II lands from other lands. <br />. "Diversions" (this table should be joined to the irrigated land table so as to only plot those <br />structures tied to irrigated lands and joined to the table of Phase II modeled irrigation <br />structures to allow one to color differentiate Phase II diversions from other lands.) <br />. The location table of Phase II base flow nodes created by the State should be imported <br />into Arc View and used to plot these locations. <br />. This project file and any associated files should be placed on cando at the conclusion of <br />this task, <br />State: Prepare a Arc View layout of the above map layers. Prepare a 36 by 48 inch map using the <br />layout. <br /> <br />Deliverables: <br />1. STATE: A revised "diversions' file containing all locations of Yampa River diversion structures <br />tied to Yan1pa River irrigated lands, <br />2, STATE: A list of structures modeled in Phase II. <br />3. STATE: A file of Phase II baseflow nodeJocations in a fom1at suitable for import into ArcView, <br />4. STATE: A ArcView project file with the layers indicated in3, above, <br />5. STATE: A 36 by 48 inch map generated from ArcView, <br /> <br />Task 3.03 <br /> <br />Aggregate Irrigation Structures <br /> <br />Objective: Determine which diversion structures should be grouped together and decide where the <br />structure representing each group's aggregated operations should fit into the river network, Develop <br />crop distribution data for each aggregated irrigation group for use in Task 3.09. <br /> <br />Assumptions: The STATE will provide an Arc View script which allows crop types to be summarized <br />for an aggregated irrigation structure, <br /> <br />Approach: <br />1. Boyle: Based on mapping developed in Task 3.02, group diversion structures not modeled in Phase <br />II together in consideration of the following factors: <br />. baseflow hydrology (primary factor) <br /> <br />Phase IlIa Scope of Services <br /> <br />\lU', <br /> <br />Jan31,1997 <br /> <br />A-22 <br />
