The water table and aquifers can be found underground. Exactly where and how good they are will depend on a lot of things, such as rainfall, underground river flows, types of rocks and how porous they are (how easy it is for water to move through the rocks).

There's a lot that goes into it and the best place to dig would be where the rock or soil is easiest to shift and the most water is closest to the surface.

There is a lot that goes into it. There's an entire branch of science called hydrogeology that is quite complex. There is a lot of high level math involved in being able to accurately predict groundwater flow.

Sounds like something I need to learn then never get to use, my favorite hobby.

While you can learn it as a hobby, I did go to college for it and worked more or less for 90 hours a week for 2 years straight.

It’s not finite, it gets put back through the water cycle.

Yes, closer to a geologic timescale. Some of the groundwater we’ve extracted won’t be returning in our lifetime, especially where compaction is a factor.
