(q) "Hypothetical Spill" is the time in any year- at which usable water would have spilled from project storage if 790,000 acre feet had been released therefrom a-b rates proportional to the actual release in every year from the starting da-te to the end of the year in which hypothetical spill occurs; in computing hypothetical spill the initial condition shall be the amount of usable water in project storage at the beginning of the calendar year following the effecti-ve date of this Compact, and thereafter the initial condition shall be the amount of usable water in project storage at the beginning of the calendar year following each actual spill* ARTICLE II. .
