000734 received from the State for purposes of this study. The Ground Rules specified using the C1 Data Set set in the condition received from CWCB.Consequently all of the analysis completed for the Technical Memoranda used the C1 Data Set data set in which this operational rule remained turned off. The necessary operational rule to model the Orchard Mesa Check Case Settlement was turned on in the C1 Data Set Fourth Revision (see Table 2 and Appendix M). 2.3.15 Comparison of Runs The difficulty of comparing the output from several model runs on a side~by-side basis was overcome by the design and implementation of several Excel spreadsheets. These spreadsheets allowed a detailed comparison of any two runs through the use of pull-down menus to facilitate selection of any storage reservoir, water diversion, or operational rule desired. In addition the spreadsheets permitted the user to view both raw data and graphs of any parameter computed by StateMod, including, but not limited to, end-of-month (EOM) storage, total release, diversions by priority, shortages and individual accounts. These spreadsheets with all of the modeled results are included in Appendix O. 2.3.16 Procedures to Estimate Outlet Works Capacities It was necessary to estimate the available release capacity for CFOPS releases in order to ensure that the StateMod runs did not assume infinite release capacity available for CROP, CFOPS and normal operating releases. Available release capacities were estimated using the following procedures. II . Monthly releases for W oHord Mountain Reservoir, Williams Fork Reservoir, Granby Reservoir and Green Mountain Reservoir were obtained from the C1 Data Set Fourth Revision. Maximum release capacities from these reservoirs were obtained from the Colorado River Water Conservation District for W oHord Mountain Reservoir, from Denver Water for Williams Fork Reservoir and from the u.S. Bureau of Reclamation for Green Mountain Reservoir and Granby Reservoir. The estimated CROP releases are presented in Table 3. Available release capacity was estimated by: A vailable Release Capacity = Max. Release Cap. . Cl Data Set Fourth Revision Release - estimated CR OP Bypass. The principal limiting factor for releases from Ruedi Reservoir is downstream channel capacity. Maximum channel capacity on the Frying Pan River near Basalt is 1,100 cfs (see Technical Memorandum No.5). For Ruedi Reservoir, available release capacity was estimated by: A vailable Release Capacity = Max. Channel Cap. - Cl Data Set Fourth Revision Release - estimated CR OP Bypass. . . 27 P:\Data \GEN\CWCB\19665\Repon Phase 2\FinalRepon12002\Final_ Draft j~.epon(l-03),doc
