<br />1827 <br /> <br />be imposed on the management of headgates within the FLCC system to assure thlO: the gates of <br />participating shareholders are closed or regulated. S\\rface water diversions and ground water <br />pumped from the aquifer must be withheld from pa~ticipating acreage. As described above, <br />exchanges could be used by the FLWB and the FLC~ to provide releases from Adobe Creek <br />Reservoir or Horse Creek Reservoir which would be int~nded to offset the impacts of the deferred <br />diversions on carriage flows to the lower divisions of thJ system. During periods of extremely low <br />flows when a deferred diversion might injure non-participating shareholders, the FLWB could meet <br />its commitments by using releases from Pueblo Reservoir. No other physical constraints are <br />anticipated at this time. <br /> <br />Water Bank Operations <br /> <br />Water bank operations would be subdivided into several operating phases, by year of operation and <br />by season of the year. The initial year would be the year of formation of the administrative portion <br />of the water bank. No water is leased or rented. Directors would be selected, administrative <br />procedures adopted and plans submitted to and appr<~ved by the State Engineer. Contracts for <br />facilities would also be negotiated. Expenses for the initial year are summarized in Section 7.8. <br />More detail of administrative requirements are prese~ted in Section 7.9. <br /> <br />The next year, i.e. the start up year, designated Year 1, the water bank would store the transferable <br />yield from participating shares in Adobe Creek Reservoir in anticipation of winter exchanges to the <br />Pueblo Reservoir account. No rental contracts would be executed and no deliveries made. Return <br />flow obligations from participating acreages, however, must be satisfied by releases, deferred <br />diversions and executed exchanges to and from storage as explained above. Return flow <br />, <br />quantification and timing are explained in Section 7.6. 1t is estimated that 1,250 participating shares <br />of average transferable yield would produce enough st~rage to initiate deliveries to renters in Year <br />2 and provide contingency for subsequent return flow! obligations. <br />, <br /> <br />In Year 2, both share leases and rental bids would be processed by the water bank. Details of this <br />process are explained in Section 7.9. As an example, refer to Table 7.3. In the example, 5,814 <br />shares, or 7,384 af of average year transferrable yieldfwould be leased and 5,000 af C.U. of renter <br />bids would be accepted in Year 2 operations. Operations analysis indicates that, on average, this <br />balance of shares and renter demands, together With!the initial storage created in Year 1, should <br />sustain the operating water bank and meet the estimatied return flow obligations. The obligation for <br />each lease year is presented in Table 7.3. <br /> <br />Operations in Years 1,2, and subsequent years, would generally be subdivided into two seasons, <br />summer and winter. The summer season might requite releases from Pueblo Reservoir after March <br />15th for two weeks to two months until flows at th~ main headgate sustain continuous deferred <br />diversions of sufficient size to meet current year re4ter requirements and return flow obligations <br />from the current as well as previous years'participating acreage. Summer exchanges to and from <br />Adobe Creek Reservoir would balance flows in the rrlain canal. For renters located above the main <br />headgate, releases would continue to be made from; the water bank account in Pueblo Reservoir. <br />The example in Table 7.3 does not include this possibility but such deliveries by the water bank are <br />considered feasible. <br /> <br />7-22~ <br />
