1 06~) and storage space is available in Pueblo Reservoir, and until all wells are equipped with metering devices, the most practical plan appears to be the fo Hawing: 1. All shareholder and company-owned wells should be made alternate points of diversion for water available to the Oxford Farmers Ditch under its second adjudicated decree dated February 26, 1887. These wells should also request priority dates as of the date of first use to insure the possibility of pumping under regulation during periods when the alternate point of diversion authority is out of priority. There is no point in tying any of the wells to the 1867 decree because river water for this decree is continuously available for all practical purposes. If the company wells were tied to the 1867 decree it is conceivable that administrative authorities could require the Company to reduce diversions from the river to 6 or 7 cfs and fill the decree from the well supply, thus causing the Company additional costs for pumping power. 2. The Oxford Farmers Ditch Company should relinquish or abandon 40 cfs of its decree dated February 26, 1887, for ll6 cfs. This would reduce the decree to 76 cfs, which is the portion of this decree that can be put to benefi- cial use under the augmentation plan. The first and second decrees would then provide a total of 89.4 cfs which is sufficient to have met all headgate require- ments in all but one month (July 1963, when the requirement was 5,600 ac-ft and the diversion would have been 5,500 ac-ft) during the 22-year period 1949-70 and much more than realistic requirements for any month except July. 3. Neither Company nor shareholder wells should be permitted to pump when the Company is diverting both its decrees in full. 4. When the headgate diversion rate is between 60 cfs and 83 cfs the Company-ow"ed we lls should be pumped if, the water is','needed, by, crops. The diversion rate of 60 cfs'is 'an ~rbitrary limit sele~ted because most of the time it is sufficient to supply crop consumptive use. Shareholders' wells should not be pumped because if all wells were pumped total water available would exceed the decreed amount of 89.4 cfs. 5. When the headgate diversion rate is between 13.4 cfs and 60 cfs the water provided may be insufficient for crop needs, and wells could be used to increase the total diversion rate to 89.4 cfs. From an administrative stand- point it must be assumed that all individually-owned wells will be used. Table 3 shows that the combined yield of the 73 wells used to irrigate Oxford Farmers land is about 50 cfs. Therefore, when the individually-owned wells are pumped the headgate diversion rate would have to be reduced to about 40 cfs. This will be more expensive than using the 'wh9~e,'hea4gate d-iv~:rs\PiJ.',!JUt is necessary to insure that ditch water plus well water does not exceed 89.4 cfs. Figure 2 shows that the total diversion rate is between 40 cfs and 60 cfs less than six per- cent of the time, and this is when such additional expense will be incurred. When the head gate diversion rate is 34 cfs or less all wells may be pumped. 6. When the 1887 decree is out of priority and the headgate diversion is reduced to 13.4 cfs the wells could no longer be pumped legally under the alternate point of diversion authority. This situation would occur every year - 23 -
