RIO GRANDE COMPACT COMMISSION REPORT

(6) San Marcial Index Supply is the recorded flow of
the Rio Grande at the gaging station at San Marcial during
the calendar year exclusive of the flow during the months
of July, August and September.

The application of this schedule shall be subject to
the provisions hereinafter set forth and appropriate
adjustments shall be made for (al any change in location of
gaging stations; (b) depletion after 1929 in New Mexico at
any time of the year of the natural runoff at otowi Bridge;
(c) depletion of the runoff during July, August and
September of tributaries between Otowi Bridge and San
Marcial, by works constructed after 1937; and (d) any
transmountain diversions into the Rio Grande between
Lobatos and San Marcial.

Concurrent records shall be kept of the flow of the
Rio Grande at San Marcial, near San Acacia, and of the
release from Elephant Butte Reservoir to the end that the
records at these three stations may be correlated. (Note:
See Resolution of Commission printed elsewhere in this
report. )

ARTICLE V

If at any time it should be the unanimous finding and
determination of the Commission that because of changed
physical conditions, or for any other reason, reliable
records are not obtainable, or cannot be obtained, at any
of the stre~l gaging stations herein referred to, such
stations may, with the unanimous approval of the Commission,
be abandoned, and with such approval another station, or
other stations, shall be established and new measurements
shall be substituted which, in the unanimous opinion of the
Commission, will result in substantially the same results,
so far as the rights and obligations to deliver water are
concerned, as would have existed if such substitution of
stations and measurements had not been so made. (Note:
See Resolution of Commission printed elsewhere in this
report.)

ARTICLE VI

Commencing with the year following the effective date
of this Compact, all credits and debits of Colorado and
New Mexico shall be computed for each calendar year; pro-
vided,that in a year of actual spill no annual credits nor
annual debits shall be computed for that year.

In the case of Colorado, no annual debit nor accrued
debit shall exceed 100,000 acre feet, except as either or
both may be caused by holdover storage of water in reser-
voirs constructed after 1937 in the drainage basin of the
