<br />Mr. Travis Smith, Superintendent <br />October 16, 2003 <br />Page 10 <br /> <br />. <br /> <br />canal and native flow at the Del Norte gaging station. Specifically, the additional water was that <br />diverted into the canal at rates of more than 145.70 cfs when the flow at Del Norte was larger <br />than 2,285 cfs. Table 6 shows the results from this part of the analysis. Additional water was <br />available for direct flow storage under the District's decree in most years of the analysis period. <br />It averaged 15,005 acre-feet annually overall and ranged from none in 2002 to 40,288 acre-feet <br />in 1980. Most of the water was available in May and June, although some was available in April, <br />July, and August. <br /> <br />. <br /> <br />We understand that direct flow storage under Priorities No. 1903-30F and 1903-34G is <br />particularly important to the District. Water nOF}l1ally becomes ayailable under these priorities <br />FI,,~"'rcV <br />early in the irrigation season before the District has cleaned the Farmers Union Canal at <br />diversion rates greater than 531.58 cfs. As a result, the District expends a great deal of effort to <br />divert and deliver this water to its landowners. Having additional reservoir capacity available in <br />which to store this direct flow water would give the District more opportunity to J~';:~the ditch <br />and would increase efficiency with which the water could be delivered to the landowners for <br />direct irrigation and recharge. Table 7 shows the direct flow water that was available for storage <br />under these two priorities. It averaged 1,542 acre-feet annually and ranged from none in 23 <br />years to 12,470 acre-feet in 1979. This is water measured at the Farmers Union diversion <br />facilities so it includes no allowances for conveyance losses. <br /> <br />As indicated above, the direct flow storage rights held by the Rio Grande Canal Water <br />Users Association and the Commonwealth Irrigation Company were decreed respectively in <br />Cases No. W-3979 and 95CW18. As you know, the Rio Grande Canal Water Users Association <br />owns and operates the Rio Grande Canal, and the Commonwealth Irrigation Company owns <br />and operates the Empire Canal. The decree in Case No. W-3979 allows the Rio Grande Canal <br />Water Users to store the direct flow water available under the priorities junior to Priority No. 363- <br />A when Priority No. 363-A can be fully satisfied from the available river flow. When Priority No. <br />363-A is fully satisfied, the Rio Grande Canal is entitled to divert 570 cfs. <br /> <br />. <br /> <br />The decree in Case No. 95CW18 allows the Commonwealth Irrigation Company to <br />implement direct flow storage under Priorities No. 361-A and 361-8 when the indexed native <br />flow in the Rio Grande at the Del Norte gaging station exceeds 2.285 cfs. ThE; decree in Case <br />No. 95CW18 further limits the Commonwealth's direct flow storage to May 20 to July 5, to <br />periods when Priorities No. 361-A and 361-8 are fully in priority and to periods when all the <br />Empire Canal priorities can be used beneficially within the Company's service area. Also. the <br />
