I developed a pond about a year ago. It was with the intention of being a wildlife pond only. Within a year I've had frogs and toads in the pond along with many invertebrates such as pond skaters and water boatmen. I also had a dragonfly visit recently. The soil type can be immaterial as you can line throughout and place different soil on top, even creating a part bog garden as I have with pitcher plants being evident. My pond is nearly fully south facing but has some shade at certain times in the day.
I would recommend you go ahead as it will enrich your garden no end.
