Frost protection can be obtained by overhead sprinkler <br />applica tion. <br /> <br />3. Zero return flow and minimum deep percolation can be <br />accomplished. <br /> <br />4. Increased production through fertilizer injection is <br />possible. <br /> <br />5. Herbicide control can be accomplished through the <br />system at minimum cost. <br /> <br />6. Furrows can be eliminated and thus improve harvesting <br />and access~bility. <br /> <br />7. Maintenance and water regulation of the district could <br />be cut in'half... <br /> <br />8. Power generation could be increased. <br /> <br />I would ask that the Board make a recommendation to the <br /> <br />Bureau of Reclamation that they rebuild the present Orchard <br /> <br />Mesa Irrigation District into a reservoir and closed conduit <br /> <br />irrigation system, so that irrigation in that area can be <br /> <br />brought out of the dark ages into the Twentie1:h Century. <br /> <br />Our attention has been directed toward dElmonstrating <br /> <br />J <br />better on-farm irrigation systems so that farmers might have <br /> <br />some idea of the various alternatives available for water <br /> <br />conservation on farm. This year Congress passed a 1.72 million <br /> <br />dollar appropriation for on-farm irrigation improvement in the <br /> <br />Reed Nash Area. <br /> <br />Many farmers will be going to automated irrigation . systems <br /> <br />of gated pipe or level ditches. The objective on-farm is to <br /> <br />minimize deep percolation and thus reduce the amount of ground <br /> <br />water which dissolves the salts and carries them on to the river. <br /> <br />In order to reduce deep percolation it is necessary to obtain <br /> <br />uniform distribution of the water over the field, Optimum furrow <br /> <br />-2- <br />
