I'm actually leaning towards the planned pond being occupied by
Shubunkins/Comets - the reasoning behind this being, that for now, I'm not
convinced that I would be able to build a large enough pond to house koi.

Living in an area where we can get heavy frosts I need to carefully
consider temperature drops in the winter (although not to the extent of
those in even colder climates) - this winter has actually been very mild
but I can't count on this. Obviously the pond needs to be dug to a depth
below the frost line to prevent the whole thing from freezing solid. From
recent observations of the reservoir for my water feature coupled with the
depth of my old pond and how far that iced up I'm pretty sure that I can
get the depth to avoid a total freeze up.....but I am now curious how low
the temperature can drop at the bottom of the pond without it adversely
affecting the fish...
=============================
One winter the bottom of my pond hit 38F. All fish survived. Several frogs
did not. IN MY EXPERIENCE goldfish are more tolerant of cold than koi.
They remain active longer in the fall.
