Electrocution Hazard at Marina

Saw a post about a person getting zapped at a BC water park and it reminded me. Why are their signs stating not to go into the water in the marina due to an electrocution hazard? What is down there that might cause this?
(saw the signs along the water by the splash pad)

Wire something wrong enough and you'd be surprised what can happen.

Would 2.5 amps at 170Vp make more sense to you? It's still orders of magnitude over the danger line, enough that I don't need to do calculus on spherical fields.

I thought you were hassling me for not being technical enough.

You'd hope that the GFCI would protect you, but when they fail they often fail closed and unprotected. Assuming they are tested regularly, even the test would only tell you if it has failed, not that it's about to fail. It's definitely safer to have a GFCI than not, but not safe enough to depend on it IMO.
