<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />March 1996 Final <br /> <br />water was applied, but not necessarily increased if more water was applied. They were <br />calculated using the Modified Blaney-Criddle Method with climatic data from the Lamar and <br />Holly weather stations. This is the same procedure as was used by both Colorado and Kansas <br />in their modeling studies in Kansas v. Colorado. The consumptive irrigation requirements for <br />these X-V lands averaged 5,396 acre-feet annually and ranged from 4,206 acre-feet in 1993 <br />to 6,953 acre-feet in 1954. <br /> <br />Table 3 shows the theoretical headgate diversion requirements for these 3,079 acres <br />during 1950-94. They were calculated by increasing the consumptive irrigation requirements <br />from Table 2 to allow for 25 percent farm losses, 5 percent lateral losses, and 20 percent <br />canal losses. These loss values were obtained from the Colorado Water Budget. The <br />theoretical headgate diversion requirements averaged 9,466 acre-feet annually, and ranged <br />from 7,380 acre-feet in 1993 to 12,197 acre-feet in 1954. The monthly diversion <br />requirements ranged from an average of 0.3 cfs in November to an average of 35.0 cfs in <br />July. The maximum monthly diversion rate was 50.4 cfs, which occurred in June 1954. <br /> <br />The consumptive use from these theoretical headgate diversions would amount to <br />58.20 percent of the diversion, or an average of 5,509 acre-feet annually, which would <br />comprise averages of 5,396 acre-feet annually (57.00 percent) of crop consumptive use and <br />113 acre-feet annually (1.20 percent) of evapotranspiration from canal and lateral losses. <br /> <br />For LAWMA's future use of its X-V water, it will be desirable to separate the direct <br />flow water from the account water. Since a significant part of the water available under the <br />direct flow right accrues to the Arkansas downstream from the diversion facilities for the <br />Lamar Canal, the logical use for the water is for delivery to the Stateline. LAWMA's account <br />water, on the other hand, can be released at different times and delivered to different stream <br />reaches or even transferred into different accounts. LAWMA will acquire ownership of the <br />entire X-V Graham,~'ticle II ~<!;;count in John Martin Reservoir. The historical inflow into this <br />---..-..------.......
