<br />Functional Specification for the Planning Model <br /> <br />In the Black Canyon case, there is the potential for institution of a Federal reserved <br />water right senior to Taylor Park Reservoir and/or the imposition of a donated water right with <br />a priority date of 1966, The reserved right has not been quantified at this tilne. The donated <br />right is for 300 cfs year around, Below Taylor Park there are the so-called "Vader rights" for <br />445 cfs which have a priority senior to the Taylor Park refill decree, <br /> <br />In the model, users will be able to modify the amounts of these rights (including setting <br />them to zero) and. to specify whether the rights call under their own priorities, are to be <br />satisfied through flow support-type agreements for releases from upstream storage, or both. <br />When and if these instream rights do call under their own priorities, the extent of such call will <br />be limited to that portion of the call that remains unsatisfied after bypasses for downstream <br />senior rights and other reservoir releases. <br /> <br />REPRESENTATION OF INDIVIDUAL WATER SUPPLY SYSTEMS <br /> <br />This section of the Specification describes the various water supply projects and systems <br />in the basin that will be represented individually in the Planning Model. The water rights, . <br />physical diversion and/or storage facilities, and operating procedures of each of these systems <br />will be represented, though not all systems will be represented at the same level of detail. <br />Generally speaking, the physical capacities, water rights, and operating rules of these systems <br />will be subject to modification by model users, although the values of these model parameters <br />used in the Baseline will represent existing conditions, The model will also permit the addition <br />of pew diversions and storage facilities to the network with water rights and operating rules <br />defined by model users. .. <br /> <br />The data describin~ the physical capacities of system facilities, the water rights <br />supporting system operation, and the operating procedures for each system will be developed <br />in detail for each system through the use of "fact sheet" questionnaires circulated to responsible <br />officials. The information on these questionnaires will be verified wherever possible by <br />reference to secondary sources. All information sources and authorities will be cited in the <br />mddel documentation. <br /> <br />Storage Projects <br /> <br />Six federal and two non-federal water storage and delivery projects will be represented <br />explicitly in the model. These projects are the Aspinall Unit, the Uncompahgre Project, the <br />Bostwick Park Project, the Dallas Creek Project, the Paonia Project, the Smith Fork Project, <br />OVerland Reservoir, and Gould Reservoir, <br /> <br />Aspinall Unit <br /> <br />Of the three reservoirs in the Aspinall Unit (Blue Mesa, Morrow Point, and Crystal), <br />only Blue Mesa will be represented in detail. Morrow Point and Crystal will be assumed to <br />operate as run-of-river power plants from a monthly perspective; only the hydraulic capacities <br />of their powerplants, service outlets, and spillways will be represented in the Planning Model. <br />The entire storage capacity of Blue Mesa will be represented in the model as will the hydraulic <br />capacities of the powerplant, service outlet, and spillway, Blue MeSa storage capacity will be <br />segregated into both dead and live storage; live storage will be further segregated into active <br />and inactive capacity. <br /> <br />Blue Mesa will be assumed to make operational releases for the following purposes: 1) <br />Gunnison Tunnel limited by contents of the Taylor Park Exchange account, 2) contract releases <br />for users within the basin, 3) contract releases for Endangered Species and Dallas/Dolores <br />project mitigation, 4) Black Canyon flow support (currently to maintain a 300 efs minimum <br /> <br />8 <br /> <br />. <br /> <br />. <br /> <br />e <br />
