We do have a hydrant at the well head, is it feasable to try and top it off with a hose? Still seems like that would be a lot of water to get 5' deep acre size? That it would take weeks or months?
Average rate from a garden hose set-up is maybe 7-10 GPM. 5-acre-feet of water is about 1,630,000 gallons. That would be 203,750 minutes of running your hydrant at 8 GPM. Which is 141 continuous days!
I would not add well water unless you go into a deep drought this summer and your water level starts falling significantly, or unless you have a well/pump combination capable of much higher water rates.
Good luck watching your initial fish stocking grow to maturity. Looks like a great start!
