How would one find the evaporation rates for an area? All good questions. I
Someone told me the following, not sure if it is correct?
To raise the water level in an 8 acre pond just 1 inch, you will need to pump over 217,000 gallons. In dry heat, your pond can evaporate on the order of 1 inch per day, so to maintain 217,000 gallons pumping 24 hours/day, one must pump at least 150 gallons per minute/. Is that correct?
Man that is a lot of water.
217,000 is correct for 1" on 8 surface acres.
And 150gal/min to recover that 1" in 1 day is correct. That's why I said 40-60 GPM to be able to recover, It might take 3 days a week to 10 days to keep up just with evap.
