<br />~ <br /> <br />~.; <br /> <br />CDM Camp Dresser & McKee Inc. <br /> <br />Draft Staging (5/17/96) <br />Page Number 3 <br /> <br />Table I may be used to break the project depletion requirements into 5 or 10 year incremental <br />growth stages or, alternatively, Figure 1 may be used to establish increments on any desired time <br />line. <br /> <br />Using the currently accepted hydrology, 1,500 acre-feet of average annual make-up flow would <br />address depletions needs through the year 2006 or 10 years from now. 1,500 acre-feet of make- <br />up flow, using the CWCB instream flow filings as targets rather than the USFWS flow targets, <br />would address needs through the year 2022 (26 years from now). <br /> <br />Monitoring and Control <br /> <br />As has been discussed previously, the current demand projections would result in a new pipeline <br />sized at approximately 48 inches. A requirement for monitoring is straightforward to address <br />since Ute Water will be metering flow in and out of the water treatment plant and reporting this to <br />the state. The notion of a restricting method of flow control is impractical because the pipeline <br />must be sized to meet the peak daily demands rather than annual volumetric limits. <br /> <br />Conclusion <br /> <br />- <br />An initial staging limit based on 1,500 acre-feet of make-up flows is consistent with the currently <br />accepted hydrology and would allow a ten year planning horizon for the recovery program and <br />Ute Water. Such an approach would allow for approval by the USFWS without the need to <br />designate an interim RP A and should be acceptable based on comments made at the May 9 <br />meeting. It is recommended that this concept be discussed further with the other members of the <br />committee on May 23, 1996. Please call if we can provide more clarification. <br /> <br />0:\8047 -11 O\DOC\51696C.MEM <br />
