So. I have two ponds with water circulation through both ponds. The larger pond is about 9' x 12' and the smaller pond about 9' x 9' on the surface, it's been hot 95-98 and bone dry here (Colorado) for the last 10 days and my small pond loses about 3" of water in 48 hours. I checked all over and do see leaks so I assume because of the heat it's just evaporation?
