Someone (I lost track in the quotes of quotes) said,
Stock tanks come in upto 300gals. The latter, being round (better for
swimming) would make a great temporary pond.

They sure do! They also come in larger than 300 gallons. We have a 7'
diameter by 2' deep one, and they get larger than that if you special
order. The price per gallon is really not at all bad.

I would advise that if you buy a new stock tank for this purpose, go for
the plastic ones. The galvanized steel tanks seem to be okay after they
have been "seasoned", i.e. had water in them for a while, but the oils
off of the fresh new tanks can harm fish.

These above-ground ponds will work fine if you can get electricity out
to them and put in a stock tank de-icer. You could put in a pond de-icer
if you have one, but the last time I looked at pond de-icers, they were
the same manufacturer, same specs, looked exactly the same inside the
box, just a bit more expensive! Use a heater guard if your temporary
pond is plastic. De-icers and heater guards are inexpensive and
available at the same feed and farm supply stores you'll be getting the
big stock tanks from.
