Is there ever a time during the summer when it's not safe to swim in a creek, pond or lake?

Question

I was told when I was younger that it was something called the dog days, but I just looked that up and it seems to be something totally different.

Answer 1

Dog days is just when you feel like laying around and being lazy. Lakes and ponds should be safe normally, except in a thunderstorm. I guess if creek gets a really strong current that can get dangerous too.

Just watch out for leeches!
