this coming spring i'm going to be helping my parents build a new pond in their back yard for their 6 koi and 2 goldfish. they are seriously outgrowing the 150 gallon one in the front yard. the fish are as follows:

metallic orange koi = 8"
black and white butterfly koi = 6" -tail
platinum koi = 5"
black and gold snakeskin koi = 7.5"
blue koi = 11.5"
peach butterfly koi = 6" -tail
calico shubunkin = 5" -tail
long-finned comet = 5.5" -tail

how big should the pond be? keep in mind this will be a TEMPORARY home for these fish, as in a couple years, my parents will be moving to their new property where they are building a house, and a new large beautiful pond. the pond we're building this spring only has to hold the fish for a year or two.

we were thinking of getting one of those huge water troughs for livestock and using that as an above-ground pond in the back yard. we can't dig in a pond because there are septic lines and power lines, and all kinds of other things under our back yard, so above-ground will have to do.
 
As big as you can get.. or get rid of some fish. Idealy you'd probably want 1000 g +, but you note that it's "temporary" thus you see you're comprimising. Increasing filtration/aeration without turning it into a whirlpool also helps in crowded conditions.
 
the water conditions are perfect, and have been the entier time we've had this pond. i tested a few weeks ago. its more a question of swimming space than anything. the fish will be fine until spring, as they're not being fed right now and are inactive due to the cold.
