There are 600 shares in the Cimarron Canal Company, 80 of which (13 percent) are owned by the City of <br />Montrose. The City takes delivery of its shares at a turnout structure into Montrose Reservoir (aka Cerro <br />Reservoir) on the basis of its pro rata entitlement to water diverted pursuant to the Canal's direct flow <br />water rights. The City's water is then conveyed to Fairview Reservoir for treatment by the Project 7 <br />Water Authority. <br />Irrigation from the Cimarron Canal generally begins around the first of May and continues until early <br />September. Many of the shareholders will continue to divert small amounts of irrigation water until the <br />first of October, and small amounts of irrigation and stock water are run until late October. The principle <br />crops under the system are alfalfa, grass hay, and small grains. <br />General Description of Bostwick Park Project <br />Water supplies in the Cimarron River drainage are generally abundant until the middle of the irrigation <br />season, at which time the supplies are severely reduced. For this reason, the Bostwick Park Water <br />Conservancy District (BWCD) was formed in 1962 for the general purpose of supplying supplemental <br />irrigation water to the Bostwick Park area. The Bostwick Park Project was authorized as a participating <br />project of the Colorado River Storage Project (CRSP). The USBR turned over the operation of the <br />project to the BWCD in 1976. <br />The key component of the Bostwick Park Project is Silver Jack Reservoir, which was completed in 1971 <br />and is located on Cimarron River approximately 20 miles above its confluence with the Gunnison River. <br />The reservoir has a total capacity of 13,520 acre-feet, including 12,820 acre-feet of active capacity and <br />700 acre-feet of inactive capacity, including dead storage. Elevation, area, and capacity data are <br />summarized in Table 2. <br />TABLE 2 <br />SILVER JACK RESERVOIR ELEVATION-CAPACITY-AREA <br />CAPACITY <br />ELEVATIONAREA (ACRES) (ACRE-FEET) <br />88021 0 <br />881052 5 <br />88201 4 11 3 <br />88302 9 32 4 <br />8840 (Inactive ±)4 3 68 3 <br />88506 2 1,20 0 <br />88608 3 1,93 0 <br />887010 7 2,87 0 <br />888013 3 4,07 0 <br />899016 4 5,56 0 <br />890019 5 7,35 0 <br />891022 9 9,47 0 <br />892026 8 11,95 0 <br />8926 (Normal WSE ±)29 3 13,52 0 <br />893031 4 14,86 0 <br />895036 7 18,27 0 <br />895041 7 22,19 0 <br />2 <br />A275 01.09.95 1.15-19 Fosha, Hyre <br />
