Cormorants might be the culprits. Depending on the fish population, they could clean out a modest sized pond in a matter of a few days. It happens around where I live all the time on smallish backwoods lakes. They seem to have "radar" for finding secret bluegill ponds, etc.
Have you ever noticed any around...or in your general region?
Cormorants could very well be the problem, They are getting bad here in Idaho along the Snake River. They are not just an Ocean or costal bird. We really need to think about controlling them somehow. A good shotgun!
