Sure, level it off and work in some organic matter if needed. I assume some might be needed because most of what you have will be subsoil. If you want to go all out, add 6-8 inches of good topsoil after leveling.

The material you have must be pretty good soil since it is growing lots of weeds. I think you have a good plan.

Agreed. Just move the dirt to the low spot and level it off. Remove the big rocks from the dirt during the process. Then add 6" to 1' top soil on top of it.

To save money, you can also first remove the top soil (6" to 1 ft maybe) from the garden-to-be area. Pile it aside. Then move the pool-dirt to the low spot and level it. Finally move the top soil back to where it was. Level it off. Add a few inches of purchased top soil or compose if necessary.

It was suggested "then add 6" to 1' top soil on top of it."

I disagree.

It sounds like you have plenty of soil, and will have an even large volume after you mix in *lots* of compost. At least 2 inches for each 6 inch depth of soil.

It really depends on the type of soil you removed to build the pool. In some places top soil is very thin. Other places topsoil is deep. I have lived in places where anything deeper than a few inches was "hard pan" which was worthless for gardening. If you are lucky, the pile of soil you have is good topsoil.

If the soil you have is of mediocre quality, mixing it with some trucked-in topsoil might work well. Just about any soil can be improved gradually by adding compost each year.

Amen, fruit nut.

You can level off so it won't be flooded. Then construct you frames for bed on top of it.
You even then mix 50/50, ie. half your own soil and half combination of
compost, topsoil and horse/cow manue. Even if what already you have is all clay(or 100% inorganic souil), it will be just fine.
Just remove chunky stones, roots, if any.
