<br />3376 <br /> <br />The above liD diversion data shows that: <br /> <br />. For 28 of the last 40 years (70% of the most recent 40-year period) liD operated <br />with less than 3, I 00,000 acre-feet of diversions, the amount IlD requested for <br />2003. <br /> <br />. lID reduced its water use in the early 1980's, while irrigating approximately the <br />same amount of acreage as during recent years, This reduction coincided with a <br />time period of increased scrutiny of liD's water use by the California State Water <br />Resources Control Board, which ruled on liD's misuse of water in June 1984 (see <br />discussion of Decision 1600 in Operating Practices - Factor 10). <br /> <br />. liD's acrual diversions did not decrease notwithstanding water conservation <br />improvements (paid for by MWD) that were found to reduce liD's water <br />requirements by over 100,000 acre-feet per year (see Operating Practices - Factor <br />10). <br /> <br />. lID diversions increased in the 1990's, while the acreages were relatively stable, <br /> <br />Reclamation concludes that lID's water order/use history shows increasing use without <br />commensurate increases in documented need. Water use in 2002 is the third highest in <br />the most recent 40-year history, while irrigated acreage is the lowest since 1984. <br />Reclamation also concludes that careful analysis of IID's water order Cor 2003 is <br />warranted. <br /> <br />FACTOR 10. GENERAL OPERATING PRACTICES <br /> <br />Part 417,3 identities general operating practices as one of the factors to be analyzed, liD <br />has a large and complex irrigation system with many individual water users and has <br />developed a comprehensive set of water ordering, scheduling and canal delivery <br />operations as fully described in NRCE 2002, Section /I C These operations and <br />procedures are focused almost entirely on water deliveries to the falms, and not on other <br />water now and management practices. The NRCE rep0l1 describes the details of the <br />water ordenng procedures followed by the fanners and the District persOlmel. The <br />NRCE report indicates that the farnlers order water deliveries in either 12-hour or 24- <br />hour tune increments and describes the complexities of "backing up" the famler water <br />orders through the delivery, conveyance and storage system, <br /> <br />While lID has a procedure for farmers to make aITangements at least 2 hours in advance <br />to have their water delivery stopped prior to Ihe end of a 12-huur or 24- hour I1lcremenl, it <br />is rarely used. FanlJe rs have little incentive to stop a water delivery early, since they <br />must still pay for the whole 12-hour or 24-hour order.
