The tables below show the proposed average monthly reductions in diversions and the <br />reductions in on -farm deliveries for each reach. Although the reductions in diversions <br />were assigned to a reach based on the distribution of irrigated acres, in some cases the <br />reductions would occur further upstream depending on the location of the mainstem <br />headgate. The amount delivered on -farm was based on the average conveyance loss for <br />each reach. Data on conveyance losses was based on county -level information obtained <br />from USGS Water Use Data for 1995. <br />Table III -12 <br />uenett irrigation - Reductions in Diversions from the Platte River (ac -ft <br />Month <br />Reach 16 <br />Reach 17 <br />Reach 18 <br />Reach 19 <br />October <br />0 <br />0 <br />0 <br />0 <br />November <br />0 <br />0 <br />0 <br />0 <br />December <br />0 <br />0 <br />0 <br />0 <br />January <br />0 <br />0 <br />0 <br />0 <br />February <br />0 <br />0 <br />_0 <br />0 <br />March <br />0 <br />0 <br />0 <br />0 <br />April <br />23 <br />42 <br />29 <br />11 <br />May <br />49 <br />98 <br />69 <br />27 <br />June <br />545 <br />1107 <br />1219 <br />1063 <br />July <br />1342 <br />3207 <br />3653 <br />3045 <br />August <br />.1233 <br />2586 <br />2959 <br />2625 <br />September <br />95 <br />180 <br />166 <br />107 <br />Annual <br />3287 <br />7220 <br />8095 <br />6879 <br />Table III -13 <br />Deficit Irrigation - Reductions in the Amount Delivered On -Farm (ac -ft <br />Month <br />Reach 16 <br />Reach 17 <br />Reach 18 <br />Reach 19 <br />October <br />0 <br />0 <br />0 <br />0 <br />November <br />0 <br />0 <br />0 <br />0 <br />December <br />0 <br />0 <br />0 <br />0 <br />January <br />0 <br />0 <br />0 <br />0 <br />February <br />0 <br />0 <br />0 <br />0 <br />March <br />0 <br />0 <br />0 <br />0 <br />April <br />14 <br />25 <br />20 <br />8 <br />May <br />29 <br />58 <br />47 <br />19 <br />June <br />324 <br />655 <br />825 <br />734 <br />July <br />797 <br />1897 <br />2472 <br />2103 <br />August <br />733 <br />1530 <br />2003 <br />1813 <br />September <br />57 <br />107 <br />112 <br />74 <br />Annual <br />1953 <br />4271 <br />5478 <br />4750 <br />A representative deficit irrigation program could reduce on -farm deliveries and <br />consumptive use by about 16,500 ac -ft per year and 8,200 ac -ft per year, respectively. <br />On -farm reductions in consumptive use were based on an on -farm efficiency of 50 <br />percent.
