<br />OGO:55 <br /> <br />with a diversion requirement of 3.16 AF/acre. Based upon the present level of <br /> <br />actual irrigated lands, the annual diversion requirement in Wyoming is 35,255 <br /> <br />AF/year, This listing of actual irrigated acreage is, however, less than the <br /> <br />acreage under Rdjudicated and unadjudicated water rights. There are approximately <br /> <br />28,000 acres of irrigation water rights in good standing in the Little Snake <br /> <br />River basin in Wyoming according to the records of the Wyoming State Engineer's <br /> <br />Office. <br /> <br />Some sources of water supply frequently dry up during the latter part <br /> <br />of the irrigation season. There is little or no storage to provide supplemental <br /> <br />water for late summer irrigation. The majority of irrigation is by direct di- <br /> <br />version of streamflow. There are no storage facilities on the major streams in <br /> <br />the Little Snake River basin in Wyoming. Therefore, water for irrigation during <br /> <br />late July, August. and September is often in short supply, thus limiting farm <br /> <br />unit production. There are several small stock reservoirs in the Little Snake <br /> <br />River drainage, but they have a minor effect on the water supply. <br /> <br />IV-2 <br />
