haus,no expert here,just telling you what bob and others told me.i would not think with your temp's you would be losing alot of water right now.with that said,i'm still not sure you have a big problem.1" a day is not alot of water.since i last wrote i called 2 friends in south louisiana(temp avg.70)and 1 guy with 7 acre lake is droping 1/2" and other guy 1 1/2 acres is dropping1/4" a day.
