What to Do When You Can't Answer a Question

Q.: Do you live on a small lake or a big lake?
Me: Yes.

I never quite know how to answer when someone asks me that. It seems there's, except for extremes, only a comparative description. Before I moved here I lived on Ward Lake, a small lake. This lake is much bigger, and float planes use it, I can't see the entire thing from my windows, and it's easy to see on maps. Is it a big lake? Lake Ontario is a big lake. So is everything between Ward Lake and Lake Ontario a medium-sized lake? What kind of a picture do those words give to the questioner, and with such a vast range is it useful at all as an answer?
