Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? How much water woudl it take?

Howdy PBers - its been a while!

A friend suggested to me that I could fill my 8.5 acre lake using a solar pump/well system. How would I determine the size and volume of water required to make a dent in filling my drought ridden property? Seems like a LOT of water to me...
