The groundwater temperature around Dallas, Texas should be approximately 68F.

I have no knowledge of the spring flows into Lake Vilbig. However, if there are any significant flows, it will be difficult to get the entire lake below 42F, even with a few days of bitterly cold air.

Hopefully, some of your threadfins will survive!
