Ponds on Deck

Question:
How do I make a pond on my deck/porch?
My back deck has a gate and lately I've been thinking about putting a pond back there for my turtles.
I have several questions so I'm hoping someone can help me out a little . . .

I've been thinking a lot about the container:
Maybe I'll get an old metal wash tub. Or I could get a barrel, cut it in half and build a wooden frame for it. Or possibly just buy a preformed pond from Home Depot and use it.
The only thing I know for sure is that I want my pond to be unique.

I've also been thinking about shade, would plants in and around it be enough?

And can this only be a summer thing? Or is it possible for the turtles to adapt when it starts to get cold again?

Any info/ideas would help me.
-Thanks so much!!!

Answer:

There are several ways you can have your pond. I would advise against any preformed one from any big box stores. They are flimsy, crack and break in a season.
Rubbermaid makes horse drinking troughs in several sizes. They run maybe $40.00 and hold up forever. You can have a pond in anything that holds water.
You could cut a hole in your deck, put a base underneath the pond and have your pond even with the deck, or maybe 6" above it.
Plants around it would be fine, but I would also add aquatic plants in pots in the water for additional shade.
It would depend on where you live if you have to take it down in the winter. If the pond would freeze solid, yes, the water would have to come out and everything in the pond as well. Heaters work, but not well enough if the pond is above ground and the weather is below freezing for days/weeks on end.
