I didn't know I had clams in my pond but I do. Discovered them last year. My pond is a dugout bog that I would have assumed had no clams. The bog had no standing water before I dug the pond. Last year when I opened up several HBG I found small clam shells in the stomach. Some fish were stuffed with them. The clams were perhaps only 1/8 inch accross. They looked to be all dead, just shell halves is all I found. They were generally brown with yellowish highlights. I've never seen a larger clam from my pond so I'm not sure if these are some type that don't get real big or of they are babies. Any guesses on what these might be here in MN?
