<br />... <br /> <br />Cot <br /> <br />r. I' .l <br /> <br />Salient conelusions dra'm fro:n this analysis fol101,: <br /> <br />1. Pumping Regimen )\0. 5 ,muld effecti yely redue e the ground1\'D. ter <br />flo\{ to about the-s2-me magnitude as the virgin flol>' that <br />occurred in the early part 0 f the 20th century (20,000 AF /yr) <br />after about 10 years of pumping. <br /> <br />2. After 50 years of pumping;, the ground1mter flow to Nexico <br />could be effectively reduced to about 60 percent of the virgil; <br />flO\\'. Consequently, the magnitude of United States pumping <br />could be reduced to maintain virgin flow conditioris. <br /> <br />3. The net results of this analysis indieate that adequate <br />measures to intercept United States groun~rater could be <br />achieved with a lesser magnitude of pumpage than required <br />under Pumping Regimen No.3. Balanced pumping conditions <br />could be achievecl, as about equal amolmts 'of water ''.'Duld <br />originate from each eountry (Table 3). <br />
