Sorry you lost your existing well. However, a new well that is only 25' deep is not that expensive. The mobilization costs for the driller may be as much as the costs to drill the well. He might cut you a deal to drill a second well near the house (or future home site)?

My biggest water well has gone under the flood waters with no ill effects. Modern well heads can be completely sealed with threaded connections and unions.

Are your 1/10th acre water holes sourced by groundwater? If so, you might be able to pump from them. You could run a gasoline trash pump and drain one on the weekend to top off your main pond. Then let it slowly re-fill, while you drain a different one the next weekend.

Alternatively, you could set a centrifugal pump very close to the water surface of your pits and move water to your main pond. Those pumps can move a LOT of water with very little electricity. I believe they come in 12V and 24V DC configurations. However, it may be more efficient to run an inverter on your solar system and run a 120V AC pump. (We do have some actual solar experts on PB that can calculate that trade off if you get that far.)

I was considering a similar option at my farm. I was going to put the solar array on posts above peak flood stage, and put the pump and electrical equipment on a floating "dock" so it would go down as I drew down the water supply, and then back up in the case of a flood.

Any of your water holes reasonably close to your main pond? 1" or 1-1/2" polypipe is pretty cheap. Might be worth testing with a gas trash pump just to see how much water can be supplied by your water holes over an extended period.
