We purchased a property last year with a pond. The pond had been leaking from years of trees on the damn and muskrat damage. I had it repaired last year

My pond filled up nicely over the winter but its now down about 6 inches over a six week period. Its not a sudden drop, its slowly reached this level.

I'm trying to determine if it is leaking or if this is just normal evaoporation. Its been well over a month since we've had any rain. Its been bright sunny days and my pond gets a steady wind of 3~5 mph. I know these can be factors for evaoporation.

This is my first pond so I have no idea what to expect as for water level.
