tion would be then: — Population 2,082,661, increasing at

 with evaporation and other losses, amounting to, say, 

 52,000,000 gallons per day, the total daily loss from the 

 reservoirs would be 183,207,643 gallons. The reservoirs, if 

 full at that time, would therefore be capable of affording 

 a reserve storage of about 600 days, or 1.64 years.
