The district could file for an amendment to the <br />decree to provide for an additional 3,000 acre-feet of storage water in <br />order to reach the total initial capacity of the reservoir if this is <br />determined to be in the project interest. <br /> <br />Leroux Creek division <br /> <br />Present decreed rights on Leroux Creek and the streams that supply <br />Leroux Creek through the Upper Overland ditch will be utilized for project <br />purposes end no additional rights will be needed. Considerable progress <br />has been J:l8de in consolidating the various rights into the Leroux Creek <br />Water Users Association in exchange for capital stock in the association. <br />Completion of this consolidation will be required for project operation. <br /> <br />~ater Requirements <br /> <br />(e <br /> <br />Consumptive use <br /> <br />() <br /> <br />Irrigation requirements for project lands have been esti~ated from <br />consumptive ~se st~dies based on climatological records of the Paonia, <br />Colo., 1-1ee,ther statio"-, which is climatically repres~l1tative of the area. <br />Consumpti'le use 'oIa:; d-,termined by the B1aney-CriddleY method. Using <br />tels rnet~od, tbe irri~~tion season consumptive use was determined to be <br />2 acre-f"et per acre fer the Fire Mountain division and 1.99 acre-feet <br />per acre for the Leroux Creek division. <br /> <br />I. <br />, . <br /> <br />. ;I.: <br /> <br /> <br />-, <br />~ <br />'*", <br />.~~ <br />.-1Il.. <br />,_. <br />',. <br /> <br />Diversion requirements <br /> <br />Diversion requirements for irrigation water were estimated on the <br />basis of consumptive use adjusted for effective precipitation, conveyance <br />losses in canals, and farm losses resulting from surface waste, deep per- <br />colation, and ditch and lateral losses. AsslL"ned data are similar for' <br />both project divisions except that higher canal losses were estimated <br />for the Fire l-buntain division because of the ~reater length of the Fire <br />~unta1n Canal.
