WATER RESOURCE INVENTORY <br />I <br />I <br /> <br />Fire Mountain Canal <br /> <br />~""-." <br /> <br />I <br />The Fire Mountain Canal has 456 shareholders and 220,155 outstanding shares. Appendix A provides of <br />listing of current shareholders. Currently, no certificates are iSsued under 50 shares due to delivery <br />constraints. Fourteen hundred (1400) shares equals one CFS, dr 0.035 CFS per 50 shares. The duty of <br />I <br />water has been calculated to be 25 shares per acre with a minimum of 40 acres (1000 shares). <br /> <br />The length of Fire Mountain Canal is 29.67 miles and the Fire Mountain Canal Extension is an additional <br />3.5 miles (Map 2, see map tube). Headgate diversion capacity is 200 CFS and 100 CFS at the Leroux <br />Creek crossing (USBOR 1957). Headgate diversions are generally held to 165 CFS due to allow for <br />fluctuations in the river level (Denison 2000). Eighty-five farm. turnouts and three. main laterals divert <br />water to FMCC water users. The greatest amount of water is used below Leroux Creek (Figure 2-1). <br /> <br />Headgate diversions usually begin in mid-April and end from early September to mid-October. The canal <br />turn-off date is dependent upon storage releases from Paonia Reservoir and annual climate conditions. <br />Approximately 81 percent of direct diversions occur from April 15 though July; 77 percent of storage <br />releases occur in August and September. For the past eleven years, the average diversions from both <br />direct flow and storage releases total only 2 percent in October. <br /> <br />FIGURE 2-1 <br />Water Distribution along Fire Mo~ntain Canal <br /> <br />2% 2% <br /> <br />59% <br /> <br /> <br />22% <br /> <br />o Upstream of Terror Creek <br /> <br />iii Stevens Gulch to Roatcap Creek <br /> <br />Il!I Jay Creek to Leroux Creek <br /> <br />I'JTerror Creek to Stevens Gulch <br /> <br />[J Roatcap Creek to Jay Creek <br />. Downstream of Leroux Creek <br /> <br />Water Bud~et <br /> <br />The water budget concept is simply a comparison of water inflows to water outflows (Figure 2-2). Water <br />inflows consist of all the sources of water supplied to the NFWCD (Le. diversions, precipitation). Water <br />outflows consist of water removed from the system (Le. evaporation, canal seepage, crop use, field runoff, <br />and field percolation). The water budget provides a mechanism to examine operational efficiencies of the <br />NFWCD's irrigation system. <br /> <br />2-7 <br /> <br />.1- <br />I <br />,--'') <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />51 <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />01 <br />I <br />
