<br />C'l":. <br />N <br />Ln <br /> <br />Table 4 is a listing of selected fields from the database which summarizes data for the <br />C irrigation method used. The information in Table 4 is sorted by irrigation method, <br />owner, and township-range-section location, Flood irrigation includes contour ditch <br />and water spreading methods. Contour ditch and water spreading were combined <br />because, as implemented, the practices are so similar as to be indistinguishable. <br />Gravity sprinkler irrigation includes gravity sideroll or wheelline systems, gravity <br />handset systems, and gravity volume gun systems. Pump sprinkler irrigation includes <br />sideroll or wheelline systems, handset systems, and volume gun systems in which <br />water Is delivered to the irrigation system by pumping. Blank entries in the irrigation <br />. method columns indicate that no information was obtained about the method used on <br />the parcel. <br /> <br />Table 5 shows crop type information for each irrigated land parcel. The information in <br />Table 5 is sorted by crop and shareowner. A crop type of alfalfa/grass hay indicates <br />that a mixture of alfalfa and grass hay which is predominantly alfalfa is grown. A crop <br />type of grass/alfalfa hay indicates a mixture which is predominantly grass. A crop <br />type of alfalfa/small grain indicates a rotation in which alfalfa is alternatively planted <br />with small grains such as wheat or barley. Grass hay in the crop column on Table 5 <br />indicates that natural grass is predominantly cut for hay on this parcel, compared with <br />grass pasture in which grass is predominantly grazed by livestock. A blank entry in <br />the crop column indicates no crop was actually grown on this parcel and the shares of <br />water owned were applied to a different parcel. <br /> <br />Table 6 contains fields from the database which show the shares per acre distribution <br />for both the Gurley and Lone Cone systems as computed from information obtained <br />in the irrigator interviews. The information in Table 6 is sorted by shareowner. Shares <br />per acre, for parcels on which both Gurley and Cone shares are used, are computed <br />by prorating the acreage based on the total number of equivalent Gurley shares. As a <br />rule-of-thumb, one Cone share was assumed to equal eight Gurley shares for the <br />calculation of proration of acreages. <br /> <br />A benefit of computer databases is that various statistical information can be <br />generated rapidly, Table 7 contains statistics, computed from the database, for the <br />data obtained from the irrigator interviews. Table 7 shows the number of shares <br />accounted for by the interview process for the Farmers' Water Development Company <br />was 6,491 of a total of 7,113 or 91%, and for the Lone Cone Ditch and Reservoir <br />Company 179 shares of a total of 216 or 83%. Acreage by crop type and irrigation <br />method for the Gurley and Cone systems are also displayed in Table 7. <br /> <br />Table 8 contains a listing alphabetically sorted by shareowner, of all the shareowners <br />and the number of shares owned in both the Farmers' Water Development Company <br />and the Lone Cone Ditch and Reservoir Company. Table 9 contains an alphabetical <br />listing of shareowners in the Farmers' Water Development Company and the number <br />of shares owned. Table 10 contains an alphabetical listing of shareowners in the Lone <br />Cone Ditch and Reservoir Company and the number of shares owned. <br /> <br />Table 11 contains a numbered listing of all the main headgates on the Gurley Ditch, <br />their name, location, size of Parshall measuring flume, and the name of irrigators <br />served from the headgate. The information compiled in Table 11 was obtained from a <br />field survey in which representatives from Boyle, CWCB, and Gurley and Cone Ditch <br />Companies traveled the length of the ditch recording information about each main <br /> <br />I <br /> <br />5 <br />
