Net losses by evaporation, as defined above, shall be
used in correcting Index Supplies for the operation of
reservoirs upstream from Index Gaging Stations as required
by the provisions of Article III and Article IV of the
Compact.

In the application of the provisions of the last
unnumbered paragraph of Article VI of the Compact:

(a) Evaporation losses for which accrued credits
shall be reduced shall be taken as the difference between
the gross evaporation from the water surface of Elephant
Butte Reservoir and rainfall on the same surface.

(b) Evaporation losses for which accrued debits shall
be reduced shall be taken as the net loss by evaporation as
defined in the first paragraph.

ADJUSTMENT OF RECORDS

'-

The Commission shall keep a record of the location,
and description of each gaging station and evaporation
station, and, in the event of change in location of any
stream gaging station for any reason, it shall ascertain
the increment in flow or decrease in flow between such
locations for all stages, Wherever practicable, concurrent
records shall be obtained for one year before abandonment
of the previous station,

NEW OR INCREASED DEPLETIONS

In the event any works are constructed which alter or
may be expected to alter the flow at any of the Index Gaging
Stations mentioned in the Compact, or which may otherwise
necessitate adjustments in the application of the schedules
set forth in the Compact, it shall be the duty of the
Commissioner specifically concerned to file with the
Commission all available information pertaining thereto,
and appropriate adjustments shall be made in accordance
with the terms of the Compact; provided, however, that any
such adjustments shall in no way increase the burden
imposed upon Colorado or New Mexico under the schedules of
deliveries established by the Compact.

TRANSMOUNTAIN DIVERSIONS

In the event any works are constructed for the delivery
of waters into the drainage basin of the Rio Grande from
any stream system outside of the Rio Grande Basin, such
waters shall be measured at the point of delivery into the
Rio Grande Basin and proper al10wances shall be made for
losses in transit from such points to the Index Gaging
Station on the stream with which the imported waters are
comingled.
