Okay, I just found these in my pool. 3 (2 of which are drowned out from the water) "larger" ants, they have a striped gaster and are about ~7mm long. I'm not sure if the smaller ant it a queen, but it was dragging its gaster, and i've heard queens can be pretty small, it's about 4mm, with a brown-redish head and thorax, brown gaster.

Smaller one (first picture it's on the left):
