Looks like it’s lost somewhere between 2-3 ft at the edge in 5 days.
Bummer.
2-3 ft of "edge" is not our normal measuring standard. True inches of vertical depth would be more accurate. Can you mark some inch indicators on a piece of white PVC or something, and walk out on some scrap wood and stick it vertically in your pond water column?
That being said, it does look like you lost several "vertical inches" in 5 days. That is probably more water loss than just your evaporation rate. If true, then you are still fighting a leak.
