Allocation of Water Within Project 7. Water delivered from <br />the Cimarron Canal to the "threshold" of Project 7 can follow <br />two different paths to three destinations. In order of preference <br />the water can: (1) bypass Cerro Reservoir and flow through <br />Fairview Reservior to satisfy the demand of Project 7, (2) flow to <br />and fill Cerro Reservoir, or (3) bypass Cerro Reservoir and fill <br />Fairview Reservoir. Water delivered from the South Canal can <br />(1) flow through Fairview to satisfy the demand of Project 7, or <br />(2) fill Fairview Reservoir. A higher priority is placed on filling <br />Cerro than Fairview, because Fairview can receive water from <br />both the Cimarron Canal (during the irrigation season) and the <br />South Canal (year-round), whereas Cerro can only receive water <br />from the Cimarron Canal during the irrigation season. If neither <br />canal is able to deliver water, the year-round demand of Project 7 <br />will take water first from Fairview and then from Cerro <br />Reservoir. The network ranks which determine this internal <br />allocation will be hardwired. <br /> <br />6. Physical Capacities. The allocation of water within the Project <br />7 sub-system is also affected by a number of non-seasonal <br />structural capacities. All of these are user-specifiable. The <br />capacities of Cerro and Fairview Reservoirs are each specified <br />, in AF. The following capacities are specified in CFS: (1) Cerro <br />Reservoir Outlet, (2) Cerro-Fairview Pipeline, which carries <br />both water released from Cerro Reservoir and water from the <br />Cimarron Canal which bypasses Cerro Reservoir, (3) Fairview <br />Feeder Ditch, which carries all water delivered from the South <br />Canal during the current month to Fairview Reservoir, and (4) <br />Treatment Plant Pipeline, which carries all water being <br />delivered from Fairview Reservoir to the Project 7 treatment <br />plant (demand) during the eurrent month. <br /> <br />Fairview and Cerro Reservoirs. Within the Project 7 system <br />these two "terminal" reservoirs are modeled as backup storage, <br />i.e. water would be released from the reservoirs in the event that <br />direct deliveries from both canals were insufficient to meet the <br />municipal demand. These two reservoirs differ from all other <br />reservoirs represented in the planning model, because they have <br />no water rights or operational parameters. The reservoirs will <br />lose water through evaporation, will be "topped off" whenever <br />water in excess of the Project 7 demand is available and will <br />release water to meet Project 7's demand only when direct <br />deliveries from the canals are insufficient. Their only other user- <br />specifiable parameters, besides total capacity, are area-capacity <br />interpolation tables and evaporation rates. Although the <br />reservoirs are relatively uninteresting from a monthly <br />perspective, given their current actual capacities, they may be of <br />interest in planning seenarios, if users assign them larger <br />capacities. The operations code does not examine or manipulate <br />these reservoirs in any way. <br /> <br />7. <br /> <br />, <br /> <br />
