The water level and well depth of your water well can be found on your well report. If you don’t have a well report, you can get a copy from your state government website, or your consumer protection branch, or your county health authority.
The well company that drilled the well should have a record of your well too.
Or if you know how to do take the well cap off safely, you may be able to measure them yourself. You can measure the water level by lowering down a line with float and weight. Measure when the line goes slack. Bring up and measure the length of the line. Do similarly without the float to get depth.
ONE CAUTION: the further down your water, the greater the chance you might get the line tangled in the submersible wiring.
