We are in the midst of a very long heat wave and not much rain. When it does come down it rains cats and dogs. I'm really amazed at the evaporation happening in my pond. I know it's not leaking.....been through that already. I'm adding about 100 gallons a day to a 1500 gallon feature. I'm wondering how others are dealing with it, as the whole eastern part of the continent is in the same situation.
