As far as I know quarry lakes are created over time as rainwater fills the quarry over years. What keeps an open quarry from getting filled the same way when it rains?
Please tell me if the flair is wrong, I estimated this one to be the closest fitting.

There’s a drain.
Water goes in, but only rises if it goes in faster than it drains out. A quarry that doesn’t fill simply leaks water faster than it can fill — through holes and cracks in the rock.
