<br />RIO GRANDE COMPACT COMMISSION REPORT
<br />
<br />(6) San Marcial Index Supply is the recorded flow of
<br />the Rio Grande at the gaging station at San Marcial during
<br />the calendar year exclusive of the flow during the months
<br />of July, August and September.
<br />
<br />The application of this schedule shall be subject to
<br />the provisions hereinafter set forth and appropriate
<br />adjustments shall be made for (a) any change in location of
<br />gaging stations; (b) depletion after 1929 in New Mexico at
<br />an~ time of the year of the natural runoff at Otowi Bridge;
<br />(c) depletion of the runoff during July, August and
<br />September of tributaries between Otowi Bridge and San
<br />Marcial, by works constructed after 1937; and (d) any
<br />transmountain diversions into the Rio Grande between
<br />Lobatos and San Marcial.
<br />
<br />Concurrent records shall be kept of the flow of the
<br />Rio Grande at San Marcial, near San Acacia, and of the
<br />release from Elephant Butte Reservoir to the end that the
<br />records at these three stations may be correlated. (Note:
<br />See Resolution of Commission printed elsewhere in this
<br />report. )
<br />
<br />ARTICLE V
<br />
<br />If at any time it should be the unanimous finding and
<br />determination of the Commission that because of changed
<br />physical conditions, or for any other reason, reliable
<br />records are not obtainable, or cannot be obtained, at any
<br />of the stream gaging stations herein referred to, such
<br />stations may, with the unanimous approval of the Commission,
<br />be abandoned, and with such approval another station, or
<br />other stations, shall be established and new measurements
<br />shall be substituted which, in the unanimous opinion of the
<br />Commission, will result in substantially the same results,
<br />so far as the rights and obligations to deliver water are
<br />concerned, as would have existed if such substitution of
<br />stations and measurements had not been so made. (Note:
<br />See Resolution of Commission printed elsewhere in this
<br />report, )
<br />
<br />ARTICLE VI
<br />
<br />Commencing with the year following the effective date
<br />of this Compact, all credits and debits of Colorado and
<br />New Mexico shall be computed for each calendar year; pro-
<br />vided,that in a year of actual spill no annual credits nor
<br />annual debits shall be computed for that year.
<br />
<br />In the case of Colorado, no annual debit nor accrued
<br />debit shall exceed 100,000 acre feet, except as either or
<br />both may be caused by holdover storage of water in reser-
<br />voirs constructed after 1937 in the drainage basin of the
