one year than the sum of 150,000 acre-feet and all gains in the quan-
tity of water in storage in such year.

C':; The Commission by unanimous action may authori ze the release
from storage of any amount of water which is then being held in stor-
age by reason of accrued debits of Colorado or New Mexico; provided,
that such water shall be replaced at the first opportunity thereafter.

In computing the amount of accrued credits and accrued debits
of Colorado or New Mexico, any annual credits in excess of 150,000
acre-feet shall be taken as equal to that amount.

In any year in which actual spill occurs, the accrued credits
of Colorado', or New Mexico, or both, at the beginning of the year
shall be reduced in proportion to their respective credits by the
amount of such actual spill; provided that the amount of actual
spill shall be deemed to be increased by the aggregate gain in the
amount of water in storage, prior to the time of spill, in reser-
voirs above San Marcial constructed after 1929; provided, further,
that if the Commissioners for the States having accrued credits
authorize the release of part, or all, of such credits in advance
of spill, the amount so released shall be deemed to constitute act-
ual spill.

In any year in which there is actual spill of usable water, or
at the time of hypothetical spill thereof, all accrued debits of
Colorado, or New Mexico, or both, at the beginning of the year shall
be cancelled.

In any year in which the aggregate of accrued debits of Colo-
rado and New Mexico exceeds the minimum unfilled capacity of project
storage, such debits shall be.reduced proportionally to an aggregate
amount equal. to such minimum unfilled capacity.

To the extent that accrued credits are impounded in reservoirs
between San Marcial and Courchesne, and to the extent that accrued
debits are impounded in reservoirs above San Marcial, such credits
and debits shall be reduced annually to compensate for evaporation
losses in the proportion that such credits or debits bore to the
total amount of water in such reservoirs during the year.

ARTICLE VII

Neither Colorado nor New Mexico shall increase the amount of
water in storage in reservoirs constructed after 1929 whenever there
is less than 400,000 acre-feet of usable water in project storage;
provided, that if the actual releases of usable water from the be-
ginning of the calendar year following the effective date of this
Compact, or from the beginning of the calendar year following ac-
tual spill, have aggregated more than an average of 790,000 acre-
feet per annum, the time at which such minimum stage is reached
shall be adjusted to compensate for the difference between the total
