Been cranking out the 70f well water at 30,000+ gph on the cold nights lately and it has made some good fog. As my 3 yr old likes to say "Daddy the wawa is smokin". It was mid 30;s this morning and we had heavy fog around the pond site. With the cold front coming next week and cool weather starting to settle in I will probably stop pumping. Time let the water temps fall until I get ready for a spring jump start.
