Circling around to this thread again, which I commented on in August 2025. To recap, I had a well dug exclusively to feed a 1.2-acre upground pond with no runoff in mid-June 2025. Central Ohio. I've been pumping 12gpm 24/7 since then. In about 130 days, I've gained about 35-ish inches with only a little rain to supplement, a long period of drought, and no runoff. I have about 8" to go before reaching full depth of around 6.5'. It is claylined on the bottom and walls (not sheepsfooted, only compacted with excavating equipment). This is the first winter with the well, so I'll flip off the switch when it reaches capacity and see what the winter snow and rain does and monitor my level. Opted for a light-switch type switch for the well pump in our nearby barn instead of a float because it was simpler. The pic is from a few days ago during seed and straw.
