Concrete base footing in crawl space

I’m currently in the process of removing a load bearing wall but prior to this I’m going to add two support columns in crawl space to help support the point loads created at either end of lvl beam, I’ve made forms for pouring a 24”x24”x12”deep footing but as I dug down 2.5” of water seeped into hole, do I need to put a gravel base? I’d so how thick and what type gravel Because I know the water in bottom will weaken the concrete as I pour it! Suggestions are highly appreciated

Why is that water there?
Concrete can be poured in water, and as long as it is placed, and not mixed, it will cure.
water weakens the mix only if you mix it in.
you would want to remove the water to avoid a mess when you displace it.
the other concern is that you want a footer on undisturbed soil.
I would use the shop vac to suck the water out, make sure the bottom of the hole is scraped to undisturbed soil, and place the concrete.

It has been raining a lot here in upstate South Carolina and I assume it is just drainage from that, I read the article and sounds like I’m on the right track
