Hi David,
That was my first thought too when I heard about it but no. Apparently during working hours in the mills, low pressure turbines drove electric generators but out of hours the same turbines drove pumps. The pumps sent 220 gallons/minute up to the hill taking 132 hours to fill the 3.5 million gallon reservoir. The total demand from the mills was 450 h.p. and during working hours 220 h.p. of that was supplied by the low pressure turbines and generators at river level and the remaining 230 h.p. was supplied by water from the reservoir driving a Pelton wheel connected a 250 volt d.c. generator.
