In our center of Illinois we saw many houses with pools. I think it would be a local jurisdiction sort of thing but I was amazed at the lack of fencing on many of them -- had never seen such a thing before.
My suggestion would be to try a 10-12 foot wading pool this year. Amazon has many options for under $100 -- of course no deck or filters etc. and a lower water level but it should give you a good idea.
And remember, the cicada-geddon this year only happens every 14-17 years most of the time!
