I really want my koi fish to make it through until next year when we

Jan's suggestion of salt is a good one.

Is there a possibility of setting up a kiddies pool next to the pond
and diverting the flow from the waterfall into it and then into the
pond? The kiddies pool would give you a place to add lots of plants
that remove nitrates from the water.
