I know the feeling. We have had an especially hot and dry summer also. Worst drought in 50+ years, and it is not over. It is STILL hot, and that is creepy for us as about this time of year we normally make the transition from shorts to sweat shirts and pants. I loose about 0.3" per day now when the pond is full, but amazingly I loose maybe 0.1" per day now that I am down about 2.5'. Now I know my leak is either up high on the back side of the dam, or the front. Since there is only one remaining wet spot on the back side, I think I know now... and it still bubbles with natural gas.
I am now at peace with my leak, if a 50+ year drought only drops me 2.5'
