Cimarron Canal Information July 6, 1993 Page 2 I'ln~",t,"l ou............. 4. Cimarron Valley Demand. The first demand "site" along the canal represents the collective acreage of agricultural lands served by the canal within the Cimarron River Valley. This is not an "aggregated" demand, since it has no water rights or "priority classes associated with it. The relevant water rights are modeled at the Cimarron Canal Headgate. Thus, users will not be able to list or specify water rights associated with any of the canal's "demand sites". Instead, users will be able to specify by means of a checkbox, whether or not each demand site will have access to diversions under the canal's direct-flow water rights. In other respects, the Cimarron Valley "demand site" will be like a normal agricultural demand. A project affiliation and augmentation eligibility, each with or without an annual limit, may be specified. Acreage, C. U. table, irrigation efficiency, return flow locations, distribution and lags, as well as a physical capacity, may be specified. The physical capacity, however, will not correspond to a single real-world structure. The default settings for the Cimarron Valley demand site, used in the Baseline and Historical Scenarios, will include both access to the canal's direct-flow diversions and project affiliation with Silver Jack Reservoir. (Any annual limit on project deliveries?) 5. Bostwick Park Demand. The second demand "site" served by the canal is the agricultural area known as Bostwick Park, which is likely to have different C.U. factors from the Cimarron Valley site and certain to have different return-flow locations (at least partially to the Gunnison River below the Black Canyon). The specifiable parameters will be identical to those of the Cimarron Valley site described above. The single-value, physical capacity will represent the most restrictive section of the canal between the headgate and the first turnout for lands in Bostwick Park. (Need the data.) The default settings for direct-flow and project water will be the same as for the Cimarron Valley site. (Any annual limit?) 6. Project 7 Demand. (See Info Theme No.8 for a more detailed discussion.) Project 7 receives water from both the Cimarron Canal and from the Uncompahgre Valley Project via the South Canal. From the perspective of the Cimarron Canal, Project 7 could receive supplemental water from Silver Jack Reservoir (or perhaps from some user-specified municipal reservoir) and it could be eligible for Blue Mesa "augmentation" via the Cimarron Canal. The default settings are: no project affiliation, but access to Cimarr~m Canal direct-flow diversions up to a set of 12 X 40 monthly limits, which represent the City of Montrose's proportionate ownership of Cimarron Canal stock. Users will directly specify such AF limits only for Project 7, in lieu of being able to specify proportionate ownerships for the three demand sites.
