Ya know what's awesome

Pump is below the opening of the caisson as best as I can tell wedged sideways below the bottom opening

There shouldn't be an opening, the well screen should be attached to the well casing. If not it will suck up sand and dirt.

That's not good.

Unfortunately I would call a well driller now. You might need a new casing and screen. I don't know if they can pull it and replace it or if they have to drill a completely new well.

It SHOULD have had a safety cable attached to the pump, and now you know why. As esshup said, when the well was drilled it should have a screen and not just an open casing at the bottom.

I'm guessing your cheapest option is to leave the old pump at the bottom and get a new one. It won't hurt anything to leave it down there. Your most expensive option would be to overdrill the well. An in between option would be to abandon/plug the well and drill a new one.

A submersible well pump shouldn't take up the entire width of the casing, so water can flow around it, and pumps are not typically set at the very bottom of the casing.

How is your well's recharge? Do you typically have enough water, or does the pump suck air in the dry season? Since it is 250 feet deep I'm making the presumption that it is set in bedrock, and that it is under "confined" conditions, which means the water level in your well will rise above the screen. If so, you should be fine just replacing the pump and leaving the old one in place.

It's worth talking to a licensed, reputable well driller in your area. They may be able to put a camera down the well and somehow retrieve it.

I’d probably drop a new pump in and try it before I ever drilled another well as said I’d say water should get past the odd pump

I would just drop in another submersible pump and see what happens. Drilling a 250' well is going to be BIG $$$$!

How deep was the pump set? How long is the pipe you pulled out?

Rough estimate, 100ft +/- using the toe to toe tape measure. I have the 100ft of pipe laying and if I put the pipe back down I hit the pump at 100ft. I have zero idea where the 250ft measure came from when I first posted this. I was talking to a well guy the other day and re-measured. Maybe the frustration of the whole situation but we are at 100 +/-. I did try to push the pump back down and got no where. Will say at one point I got past the pump and it dropped way down after the pump. Had a well guy out yesterday but he won't put the camera down with the electric wire still attached. Too much risk for the camera to get hung up. Advice he gave me. Cant do anything with the wire attached. Cant reuse the wire. Can't use the pump that's down there. He told me MAYBE if I winched on the wire just maybe the pump may pop loose. Regardless, wire has to come out before we do anything so either it pops loose or the pump comes up. Thinks maybe because the limestone, a rock or something dislodged and is causing the pump to be stuck. Asked him about not being a screen at the bottom. He said in this area and it being a small residential well and the age that usually, in this area, there isn't one. Idk, but wish me luck after I get off work. Any bets on the outcome of said pump being in my hands later?

I have a drilled well, 4 inch casing, 117ft. My pump is 7ft down and has a cable tethered to it. My outside hydrant broke this spring, I called a well guy to come fix it. He carefully unscrewed it, pulled it out of the ground, put a new piece on the bottom and pushed that sucker back down the same hole and screwed it into place. Now had I done that I'm sure a 1/2 inch rock would have fell in the hole and I would have had a excavating company out here digging up my yard...LOL
