I'd put some sort of ruler or yardstick in the pond to get an accurate measurement of water loss per day or week. That way you can calculate how much water you will need to add per day or week to keep the water level stable.

FYI, I'm adding roughly 30-35 thousand gallons per day and I'm only raising the water level about 1/4" per day.
