I used to like snow skiing and things like that. But these days I prefer our weather, even though we can get a few colder days here on the La and Tx border. Seems like older I get the less I like putting on layers of clothes.
This winter I just hope to keep my TFS living in the pond. And that means it needs to stay warmer than 42 on the bottom of the pond. I have wondered if running the well water would keep the water a little warmer. Well should produce around 1/2" of water across the pond.
If I recall correctly, well water typically has a temp of around 62-67*f, so it would definitely help warm your pond.
However, it would have to be oxygenated prior to injection since well water has no oxygen. Then theres a question of turnover with warmer water gathering on top. Eventually the volume of added warmer water may create a turnover condition.
I hope everyone stays safe and warm with this next significant weather event passing thru. They're saying we may see snow here in the deep south.
