Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Daily Summer Evaporation Rate

My pond is a ground water pond, in sandy soil, so the water levels fluctuate greatly depending on the water table. I'm pumping roughly 25 gpm into the pond 24/7 and even so the pond is still dropping. Right now I'm 27" below full pool.

When the farmers are running the center pivot irrigation systems, and the well isn't running, I can drop 1" per day.....
