OP is just north of New Orleans.

That should be warm enough that TFS will survive the winter temps.

Lake Texoma (at the Oklahoma-Texas border) has a huge population of TFS that creates a great striper fishery. At that latitude, they do suffer some diebacks once or twice a decade. However, some TFS seem to always survive in the deep water.

I think the OP should be fine (temperature wise) if the pond does have some deeper water.
