Swimming with the Fishes

Note that there is absolutely no evidence in this photo that she was pushed.

So it is possible, though not necessarily advisable, to swim in Lake Gatun.  It's important to avoid passing ships.  It is also helpful to avoid water snakes, crocodiles, caimans, jaguars, and swimming within half an hour of eating lunch, or even longer if beans have been consumed.  My daughter chose to follow none of those rules.
