I'm thinking your talking to me about tacos. Yup, I'm going with heat. It has been running around 100f daily here, with some wind. We are starting to see the water getting less already. We are gonna try and blow the well out/recondition it this year. We have never done anything to it in ..... Hum, next year it will be thirty years. Dang I'm old...eeek! I understand the sides of the well walls sluff down into the area where the water holds. We will prolly redo the whole system, replacing the holding tank too. If it would just rain more. Global warming, myth or fact? I'm in the fact camp. Have a wonderful day Rose. Ima old lady rambling in your thread today.
