As shown in tuble 16, it. was not possible to fully meet the ideal
irrigntion din>rsion df'mund of the Rio Grnlldt~ DidsioTl in all yenrs
of the study. During the period 1928-1960. t}w diversions averaged
48.200 llCTt>-feet less thnn thc ideal divcrsion (IeOland. The diversion
defit'il'ncies l'ould be Inffrely offset b.'" use of ~mknged wlltpr. The
potelltinluse of sulvug'ed ground wuter nnt! drnin flow is indicnted in
tllble 17 to Ilverage 41. 600 ncre-feet per yt'tlr when sneh snknged wutl'r
