Bob, except for one good 3" rain it has been very hot and dry here, I am losing 3/4" daily. I'm waiting for cooler weather to get a more accurate measurement, not sure how much is evaporation. Bucket test have shown a 10" loss overnight:) deer, lots of critters at night! guess I need some chicken wire. Thanks for asking Bob, how is your pond doing, any good rains? Guppy1 that 3/4" loss in your bucket test may be close, it would be interesting to know what others evaporation amounts are.
