Bu Rec estimate of annual irrigation benef i ts. assuming: <br /> a. 78.430 AF of project water delivered to farm head gage <br /> b. Crop yields projected for yea r 2010, using 8-yea r base per i od <br /> for alfalfa, 13-yea r base period for sugar beets <br /> c. All project water will be used for irrigation $6.3 mi 11, ion <br /> NOTE : Direct irrigation benefits are $63.18/AF annually. and <br /> total irrigat ion benefits are $79.00/AF annually. <br />. 2. Modification factors: <br /> a. Project water mod factor: . . 128% <br /> (Divide project water estimate from Part by 78,430) <br />
