If I had to do it, and I'm not recommending this at all, but if it were me, I'd have a set of rubber hipwaders on, rubber gloves, make my way to the panel and kill power. If the water around the house has receded, I'd pump out a basement with a portable gas powered pump before entering it.
    Residential basements are rare to nonexistent in Houston.

    Jraef has kindly provided a link to procedures for refurbishing/replacing equipment that has been water damaged. None of the procedures are carried out live.

    Personally, I wouldn't consider entering a building with live, submersed electrical equipment. I think many others wouldn't either so, to that extent it is a hypothetical and the question of how well the type of water conducts is an irrelevance. IMO.

    The physics of the scenario is what intrigued me. If you read my other posts you would see that safety is my real world concern.
    Nowhere in my post did I suggest I was gathering information in order to attempt the scenario you described.

    I described it as hypothetical. Which is agreeing with your take.

    Michigan. It's a beautiful penninsula, I've looked around.

    Is there one? To me, that's like asking if there is a proper protocol for entering a powered dwelling that is on fire. The only way one should do either is in a life or death situation, IMHO.

    Nicely put.

    I don't think OP was necessarily asking how to enter the flooded house while circuits are energized, I think he was asking what goes on in submerged energized wiring.

    What could go on since it's hypothetical.

    I think hypothetical meant there is no specific case he is referring to, just a general question of what happens when energized 120 volt item is submerged in water.

    Then he have simply asked that general question. Nothing hypothetical about it.

    Somewhat related, I've been to quite a few different countries and have seen practices that many would have raised eyebrows at.
    One was motor maintenance in the Far East. The motors were dismantled, the end bells and rotor removed. The stator was flushed out with water and then left to dry in the baking hot sun. Means and resources. So getting something soaked isn't the end of the world Operating it under such conditions is another matter.
