Dallas freezes in the winter. Discus could probably survive 90 - 92 degree water, but they're not going to survive the 55 degree water you would have in the winter.
If you have a shaded pond, and can keep the water clean, I think they could survive in the summer there. If the water starts approaching 92 - 94, it's time to get them out. No chance on winter without major heating.
It's also going to be extremely difficult to catch a Discus in a pond. It's hard enough in a tank where you can see them and use 2 nets. Keep that in mind if you try this, you may need to drain the post to a puddle to have a chance of getting them out. Also watch them for signs of low oxygen. Once temperatures go above 90, water has virtually no ability to hold oxygen. Even in a large space, they could be gasping for a breath.
