IN THE AQUEDUCT FOR THE YEAR.
IF THERE IS AT LEAST 200,000 AF OF SURPLUS ~ELEASE REMAINING, SET
SURPLUS DELIVERY TO MEXICO = 200.000 AF. AND
SURPLUS DELIVERY TO MEXICO FOR POWER OPERATIONS: REMAINING SURPLUS RELEASE.

*

[COMPUTE ANNUAL SURPLUS RELEASE FROM L~KE POWELL:}
EOWY POWELL TARGET STORAGE = A SPECIFIED PERCENTAGE (USUALLY 50%) OF:
POWELL AND MEAD COMBINED CONTENTS + AVERAGE NATURAL FLOW AT LEES FERRY
UB AND LB USES - SURPLUS RELEASE FRDM MEAD.
EOWY PREDICTED TOTAL UB STORAGE : EOWV POWELL TARGET STORAGE + CONTENTS OF
FLAMING GDRGE. BLUE MESA. AND NAVAJO.
IF EOWY PREDICTED TOTAL UB STORAGE .LT. THE REQUIRED 6024 STORAGE + AVERAGE
NATURAL FLOW AT lEES FERRY - NATURAL FLOW AT LEES FERRY AT A SPECIFIED
PERCENTILE (USUALLY LOWER DECILE). THEN SET EOWY POWELL TARGET STORAGE
THE REQUIREO 602A STORAGE + AVERAGE FLOW - SPECIFIED PERCENTILE FLOW -
CONTENTS OF FLAMING GORGE, BLUE MESA. AND NAVAJO.
SURPLUS RELEASE FROM POWELL = POWELL CONTENTS - EOWY POWELL TARGET STORAGE +
AVERAGE NATURAL FLOW AT LEES FERRY - UB USES - POWELL MINIMUM ANNUAL RElEASE_
IF THE TOTAL RELEASE FROM POWELL .GT. THE TOTAL RELEASE FROM MEAD. AND
POWELL CONTENTS .LT. MEAD CONTENTS, SET SURPLUS RELEASE FROM POWELL:
TOTAL RELEASE FROM MEAD - POWELL MINIMIUM ANNUAL RELEASE.
IF SURPLUS RELEASE FROM POWELL = 0 OR LESS. SKIP DOWN TO "BEGIN SURPLUS
MONTHLY DISTRIBUTIONS." (MONTHLY POWELL RELEASES WILL REMAIN EQUAL TO
THE MONTHLV RELEASES SCHEDULEO TO MEET THE MINIMUM OELIVERV REQUIRfMENT.)

[COMPUTE MONTHLY POWELL RELEASES:]
TOTAL ANNUAL RELEASE FROM POWELL'" MINIMUM ANNUAL RELEASE + SURPLUS RELEASE
FROM POWELL.
COMPUTE THE MAXIMUM OESIRED MONTHLY RELEASE FROM POWELL BASED ON 6 OF 8
GENERATOR UNITS OPERATING AT MAXIMUM CAPACITY.
DISTRIBUTE HALF OF THE TOTAL ANNUAL RELEASE FROM POWELL TO MONTHS OCTOBER THRU
MARCH IN PROPORTION TO THE MINIMUM RELEASE SCHEDULE. IF ANY MONTHLY RELEASE
EXCEEDS THE MAXIMUM DESIRED MONTHLY RELEASE. DELAY THE EXCESS TO THE NEXT
MONTH.
(MONTHLY MEAD RELEASES ARE COMPUTED IN SUBROUTINE SURPLUS BASED ON NORMAL
DELIVERIES TO LB USERS AND SURPLUS DELIVERIES TO CAP, MWD. AND MEXICO. )

BEGIN SURPLUS MONTHLY DISTRIBUTIONS:

,

*

(SURPLUS MONTHLY DISTRIBUTIONS FOR CAP AND MWD WERE COMPUTED IN
OCTOBER AS PART OF THE ANNUAL SURPLUS COMPUTATIONS. THIS SECTION
DISTRIBUTES THE ANNUAL SURPLUS DELIVERIES TO MEXICO.)
IF MONTH IS APRIL THROUGH SEPTEMBER, SET THE ANNUAL SURPLUS DELIVERY TO MEXICO
FOR POWER OPERATIONS = 0_
IF THE SURPLUS FLAG'" 0 (OFF). SKIP DOWN TO "BEGIN SHORTAGE COMPUTATIONS."
COMPUTE THE SURPLUS DELIVERY TO MEXICO FOR THE CURRENT MONTH BY PROPORTIONING
THE 200,000 AF SURPLUS DELIVERY TO MEXICO ACCORDING TO THE NORMAL MEXICAN
. DEMAND SCHEDULE AND BY PROPORTIONING THE SURPLUS DELIVERY TO MEXICO FOR
POWER OPERATIONS ACCORDING TO A GENERALLY-OBSERVED HISTORICAL MEAD RELEASE
PATTERN.
IF THE NORMAL CONSUMPTIVE USE BELOW PARKER DAM + THE MONTHLY SURPLUS DELIVERY
TO MEXICO .GT. THE MAXIMUM AVERAGE MONTHLY PARKER POWERPLANT RELEASE, SET
THE MONTHLY SURPLUS DELIVERY TO MEXICO'" THE MAXIMUM AVERAGE MONTHLY PARKER
PQWERPLANT RELEASE - THE NORMAL CONSUMPTIVE USE BELOW PARKER DAM.
EXIT FROM SUBROUTINE APPOR.
