Prosent irrigation praotices within the arow. might be ohanged so <br />t!ul.t a moreeconomioal use of the water oould be aocomplished. <br />It is maintained by residents of the. area that conaumptive <br />use rates are low on suoh lands and that return flows from irrigation. <br />beoome of major importanoe to downstream users, The North Park investi~ <br />gations of the Colorado Water Conservation Board show the consumptive <br />use in that area to be 0.80 aore feet per acre of whioh 0.7~ aore feet <br />is chargeable to agricultural lands, The Chalk Creek area would pro- <br />bably be somewhat higher, but conditions are similar within the two areas. <br />Whilf!l demands on the river by irr:l.l1lLtion in the Ch8.1k: Creek arelll would be <br />negligible, it must be admitted that any increase in irrigation would <br />increase the amount consumed, Acorued benefits from return flows' to <br />downstream users might be considere4 in justifying upstream development, <br />ll!. EClonomio feasibilitJ:., No major ohanges in the present <br />land use eoonomy of the area should be oontemplated. The area is well <br />suited for ranohing operations and the produotion of forage orops <br />with some small grains. Consequently it is doubtful if the average <br />gross inoome per acre of the irrigated lands would exoeed $15 per acre. <br /> <br />"'1- <br /> <br />.~-~ <br />
