What is the initial water volume in the reservoir?


Let me accept the current volume of the reservoir is #10,000,000,000# gallons (or #2,641,729# cubic meters).

If there is no evaporation from the reservoir and there is no loss (e.g. infiltration into the ground), the final water will be:

#10,000,000,000 - (52times125,000,000)# gallons

Note that there are 52 weeks in a year

#=3,500,000,000# gallons water will be available after a year.

If you say the initial water volume stored in this reservoir is V, the final volume after a year will be

#V - (52times125,000,000) = V - 6,500,000,000# gallons
