<br />21 <br /> <br />Pumping Re~imen No.2 <br /> <br />,Yuma Hesa Wells (60,000 AF/yr) <br />Yuma \'alle~' \,'ells (50.000 _-\F/yr) <br />Yuma Hesa \vells (150,000 AF/vr) <br />Sonora, ~lexico \{ells (160,000 AF/yr) <br /> <br />The computed change in 1;ater leyels after 10 years of pumping <br />are sho'\~ on Figure B-IO; and after 50 years of pumping the <br />effects are sho',~ on Figure B-11. The quantitative effects after <br />pumping 10 and 50 years are given in Table 2. A recapitulation <br />of the analysis at the end of 50 years follO\;s. <br /> <br />a) Reduction and reeharge from Colorado River ,;ould be <br />40,600 AF/yr (50-year ~verage); <br /> <br />b) Depletion of surface drainage flows at S.l.B. would be <br />84,000 AF/yr (50-year averagc); <br /> <br />" <br />1 <br />I <br /> <br />c) Depletion of ground1mter storage in United states would <br />be 4,660,000 AF at the end of 50 years; <br /> <br /><:1) Depletion of ground'l'ater storage in Hexico ,wuld be <br />8,760,000 AF at the end of '50 years; <br /> <br />I <br />, i <br />I <br />I <br /> <br />e) The f16w from groundwater storage at the sout~ern limit <br />of the analog model (about 30 miles south of Arizona- <br />Sonora boundary) would be 18,800 AF/yr (50-year average). <br />
