<br />nun ~ ! 0 <br /> <br />July 6, 1993 <br /> <br /> <br />Gunnison Planning Model - Info Theme No.3 <br /> <br />Information Related to Cimarron Canal <br /> <br />(This replaces "Infomuiiion ReWed to Canals," because the Cimarron Canal is <br />the only instance in the model, aside from the Uncompahgre Valley Project, of a <br />physical conveyance serving a set of demands that have some shared and some <br />discrete privileges.) <br /> <br />The Cimarron Canal is a non-standard construct. It serves three "demand sites:" <br />(1) agricuIturallands within the Cimarron Valley, (2) an area of agricultural lands in <br />Bostwick Park, and (3) the municipal water treatment plant referred to as Project 7. <br />The diversity of these "demand sites," and the special operational requirements of <br />Project 7, in particular, require some unique design features for both the canal and the <br />on-canal demand sites. . <br /> <br />l. Water Rights. Three direct-flow water rights are situated at the <br />canal headgate, and a fourth user-specifiable water right" slot" is <br />provided. The allocation of diversions under these water rights <br />among the three demand sites is determined by an internal order <br />of precedence together with a user-specifiable 12 X 40 set of <br />"throttle" values on the amounts delivered to Project 7. (See the <br />discussion of the individual demand sites and their "orderings" <br />below, and theme number 8.) <br /> <br />2. Varying Canal Headgate Capacity. The canal cannot be <br />operated during the winter. To represent this seasonal physical <br />limitation, there will be 12 X I set of capacities on a single <br />physical-capacity link just below the headgate. Users will specify <br />these capacities in CFS, and they will be converted internally to <br />AF/month. <br /> <br />3. <br /> <br />Project and Augmentation Deliveries. At the canal headgate, <br />there will be two separate "gate" arcs for the project deliveries <br />and augmentation steps. However, project association and <br />augmentation eligiblity will not be direct attributes of the canal. <br />These normal attributes of demands will be associated <br />individually with each of the three demand "sites" served by the <br />canal. These demand sites have different characteristics, as <br />described below, and may have different access privileges to <br />direct-flow, project and augmentation water. The three sites may <br />even be associated with different projects. <br /> <br />':, <br /> <br />{' <br /> <br />" <br /> <br />"' . 4a.:.~L<i. <br /> <br />
