0007;.;5 West Slope Comments The CFOPS releases of 20,000 acre feet or 1,008 cfs (on average of occurrences), will be provided when the flow triggers of 12,900 cfs to 26,400 cfs at the Palisade gage are realized. Planning for the implementation of CFOPS must begin with the March I forecast of available water supply for the various contributing reservoirs and the estimate of potential runoff at the Palisade gage. Implementation of the CFOPS efforts will be through the existing CROS working group. CFOPS peak flow augmentation will be provided on an equal basis from Green Mountain Reservoir, Granby Reservoir and Williams Fork Reservoir (6,667 acre feet each on average). Green Mountain Reservoir will participate to the extent that the sum of CROS inflow bypasses and CFOPS releases can be passed through the outlet works (turbines and bypass tubes) and over the spillway. Or as limited by USBOR for dam safety purposes. The contribution from Green Mountain Reservoir will come from the 100,000 acre foot pool and any portion not used for CFOPS will be considered to be in the 100,000 acre foot pool for previously identified purposes, not carried over into another year for CFOPS releases. The ability of Green Mountain Reservoir to participate will be ascertained at the adjusted start of fill date. Drought provisions must be included in the rules under which CFOPS releases and CROS bypasses are made, which recognize the potential problems related to making fish bypasses and releases following dry years. Triggers will include: forecast storable inflow, reservoir contents (in individual pools) and peak flow forecast. CFOPS releases and CROS bypasses are voluntary. The Recovery Program and USFWS must verify and demonstrate a measurable positive fish population response from peak flow augmentation activities, beyond reporting increases in gaged flowso If CROPS and CROS operations are not shown to contribute to populations necessary for recovery they will be discontinued, Reduced reservoir levels which do not impact a reservoir's ability to meet its intended purposes are not to be considered an impact on facility firm yield. II An insurance pool must be included to meet obligations of participating reservoirs should they not refill the "fish hole" created through peak flow releases. The insurance pool obligation will be met through use of the USFWS' environmental pools, first from Ruedi Reservoir and second from Wolford Mountain Reservoir. All exchanges necessary to implement the use ofRuedi and Wolford reservoir waters to meet the delivery obligations of the participating reservoirs will be the responsibility of the USFWS.
