Therefore, it was not necessary to perform any <br /> <br /> <br />operational studies involving storage reservoirs. <br /> <br />0.4.3 Cropping Pattern <br /> <br /> <br />For the preliminary analysis of PIA, a cropping pattern with the <br /> <br /> <br />highest net agricultural returns was used. Table 0.3 identifies <br /> <br /> <br />this cropping pattern as well as the net agricultural return. Lands <br /> <br /> <br />in the Animas and Florida Watersheds were located within climatic <br /> <br /> <br />zones 0, E, and F. <br /> <br />0.4.4 Preliminary PIA Analysis <br />A preliminary PIA analysis was \?erformed comparing a parcel's <br />payment capacity with a preliminary estimate of the cost to pump <br />water f-rom the river to the pa-rcel. This prelimina-ry water cost was <br /> <br /> <br />based on the static pumping lift (the difference in elevation from <br /> <br /> <br />the water surface in the river to the elevation of the parcel) for <br /> <br /> <br />gravity irrigated fields or plus a field delive-ry pressure of 60 psi <br /> <br /> <br />for sprinkler irrigation. Detailed tabulations of the analysis are <br /> <br /> <br />shown in Appendix 0.1. Tables D.4 and 0.5 identify only those <br /> <br /> <br />parcels with an initial positive residual \?ayment capacity requiring <br /> <br /> <br />further consideration. <br /> <br />An off-farm irrigation transmission system was designed for those <br /> <br /> <br />parcels showing a positive residual payment capacity. Those <br /> <br /> <br />calculations are shown in A\?pendix 0.2 and summarized in Table 0.6 <br /> <br />10 <br />
