If it was water only it probably popped out the freeze plug or plugs. It happened to me long ago on a straight 6 camaro I had. Thankfully the block didn't crack. I hope yours didn't either.

I froze a buick motor one time and it blew the head gasket which leaked out and in so it had no white smoke either...
freeze plugs or frost plugs are actually an incorrect term though very commonly used, including by myself. they are core plugs, the holes that these plugs fit into are used to remove the sand used in the casting process. luckily they have a tendency to pop or get pushed out when the coolant freezes.
i can't identify the engine in the picture, but its always best to start at the top and work your way down. is the intake gasket leaking or anything that threads into the intake leaking. intake gaskets can leak internally or externally. same with head gaskets, its nice to hear that no white smoke is coming from the tail pipe when running. some cylinder heads have core plugs in them also. you may need to use a mirror or if you know someone with an inspection camera to borrow. plumbers and mechanics use these to see in places you normally can't view.
You should all the freeze(Core) plugs if one of them released. When it gets warmer, you could use GM Coolant tabs to seal it up temporarily. That stuff works great.
If it is a freeze plug the easiest in car replacements are rubber expansion plugs, it slips in the hole and then you tighten it.
Available pretty much everywhere.
Core plugs usually aren't complicated as much as they are a PIA to get to. I'd get one of the rubber plugs that 565BBC suggested as I've used them before and never had any issues. Although if you watch Roadkill, check out their Ranchero to Alaska episode, (I think it's episode 2 or 3) they had quite a few issues with them. Great episode.
Why were you running it with water in the radiator? Seems that a $20 worth of antifreeze during the dead
of winter would have prevented all this from happening. Freeze plugs are not fun or easy to get to in the back of the motor.

It has to get more than few degrees under 32 for water the freeze solid in a block so maybe you have a frost plug that is rusted
