I attempted a repair on my pond and up until a week ago, it has only been 1/4 full and barely over the patch due to lack of hard rain. Now it’s up about 90% full and time to test water loss. Temps have been in the mid 90s with wind past few days and my pond dropped 1/2 inch per day. It used to drop an inch at full pool till reaching half pool where it slowed to 1/2 inch. Seems I slowed it down but I’m not sure. Has anybody tracked their summer water loss vs winter? Really interested to hear from guys that drop nearly zero in the winter.
