Never mind the carp, but please could you wait until late Summer to fill in pond- which is probably full of wildlife at the moment. Newt and frog tadpoles, dragonfly larvae, and so much more.
Put an ad at your local vets?
I agree. Supposing the koi pond is a "natural" pond, it would be sad to destroy such an area that has so much wildlife, such as frogs, newts, etc. that are so very important in fighting garden pests such as slugs, mosquitoes.
