BYPASS THE EOUALIZING OF POWELL AND MEAD.
ADDITIONAL RELEASE FOR EQUALIZING = HALF THE DIFFERENCE BETWEEN THE EOWY
PREDICTED CONTENTS OF POWELL AND MEAD. DIVIDED BY THE NUMBER OF MONTHS
REMAINING UNTIL THE EOWY.
POWELL RELEASE = THE REMAINING POWELL RELEASE PROPORTIONED BY THE RELATION OF
THE POWELL RELEASE SCHEDULED FOR THE CURRENT MONTH TO THE POWELL RELEASE
SCHEDULED FOR THE CURRENT MONTH THRU SEPTEMBER. PLUS ANY ADDITIONAL RELEASE
FOR EQUALIZATION.
LIMIT THE POWELL RELEASE TO THE MINIMUM (ENVIRDNENTAL) OR MAXIMUM (POWER)
RELEASE IF NEEDED.
IF MONTH IS 1 THRU 7, EXIT FROM SURPLUS.
COMPUTE ESTIMATED MEAD INFLOW.
COMPUTE AVAILABLE SPACE IN POWELL AND MEAD.
IF IOS(1).GT.O, BYPASS MIN12. EXIT FROM SURPLUS.

COMPUTE THE MINIMUM REOUIRED FLOOD CONTROL RELEASE FROM MEAD FOR THE MONTH,
BASED ON ESTIMATED MEAD INFLOW AND AVAILABLE SPACE IN POWELL AND MEAD.

IF A FLOOD CONTROL RELEASE IS REQUIRED, TURN THE SHORTAGE FLAG OFF.
IF THE FLOOD CONTROL RELEASE .GT. SCHEDULED DOWNSTREAM DEMANDS. CALL
SUBROUTINE FLOOD TO DISTRIBUTE THE EXCESS RELEASE TO CAP. MWD. AND MEXICO:

DISTRIBUTE THE EXCESS RELEASE EVENLY TO CAP & MWD. IF CAP IS NOT YET TAKING A
SURPLUS, MWD CAN TAKE UP TO ITS CAPACITY.
IF EITHER CAP OR MWD REACHES THEIR CAPACITY BEFORE THE EXCESS IS FULLY
DISTRIBUTED, THE OTHER AQUEDUCT CAN TAKE UP TO ITS CAPACITY.
IF CAP & MWO ARE BOTH AT THEIR CAPACITIES, REMAINING EXCESS GOES TO MEXICO.

IF THE MEAD RELEASE (BASED ON DEMANDS) .LT. THE MINIMUM REQUIRED FLOOD CONTROL
RELEASE, SET THE MEAD RELEASE = THE MINIMUM REOUIRED FLOOD CONTROL RELEASE.

HYDROLOGICALLY BALANCE THE SYSTEM FOR THE MONTH:
[FLOW IN THE RIVER IS A SINGLE VALUE THAT IS CARRIED FROM SEQUENCE POINT TD
SEOUENCE POINT AND ADJUSTED FOR DIVERSIONS. RELEASES, AND INFLOWS. ]
IF THIS IS THE FIRST SEQUENCE POINT, SET FLOW IN THE RIVER = THE INFLOW AT
THE FIRST SEQUENCE POINT.

IF THE DEMAND IS CAP, MWD, SNWP, OR MEXICO, SHORT OR SURPLUS THE DEMAND BY
THE AMOUNT DETERMINED IN SUBROUTINE APPOR.
IF THE DEMAND IS A PUMP EO DIVERSION FROM A RESERVOIR, COMPUTE THE AMOUNT OF
DIVERSION. THE WATER WILL BE REMOVED FROM THE RIVER WHEN THE RESERVOIR IS
PROCESSED. OTHERWISE:
FLOW IN THE RIVER = FLOW IN THE RIVER - THE DEMAND.
IF THE FLOW IN THE RIVER IS POSITIVE, SKIP DOWN TO SUBROUTINE RETURN.
IF THE FLOW IN THE RIVER IS NEGATIVE. CALL ON UPSTREAM RESERVOIRS FOR
A POSSIBLE SUPPLY AS FOLLOWS:

RANK THE uls RESERVOIRS THAT ARE DESIGNATED TO SUPPLY ADDITIONAL WATER IN
DESCENDING ORDER BY THE SIZE OF THEIR CURRENT SURFACE AREA.
