Crop System ~ Ac. 6,500 3,000 <br /> <br />1/ Sample of 25 percent of predominantly surface water supplied systems. <br />2/ This is a non-structural practice involving improvements such as: <br />irrigation scheduling, time of irrigation set, optimum stream size, <br />tailwater management. <br />1/ Change from surface systems to sprinkler systems. <br />~ Non-structural practices of management of crop residue. <br /> <br />Systems studied supply water to over 264,000 acreas, this is about 25 <br />percent of all the land irrigated with surface water supplies. Based upon this <br />sample it can be concluded that structural practices will be difficult to <br />economically justify. The five systems, in which structural improvement were <br />justified, had an inadequate water supply. In these systems small changes in <br />efficiencies produced large changes in crop productions. Irrigation water <br />management proved to be economically justified in all systems studied. From this <br />it is concluded that improved management is needed through out the basin. There <br />were also 2 systems found to have viable .onfarm structural needs. <br /> <br />Over 58 million dollars will be needed to construct the improvements found <br />to'be economically feasible in the systems studied. About four times that amount <br />is needed to provide needed improvements through out the basin. Some loans and <br />grants may be available from the State and Federal governments to assist in <br />implementing these projects. <br /> <br />- 2 - <br />
