Aha! I hadn't thought about a fish blocking it then getting flushed away. I could see a bluegill doing that. I guess I'll just keep re-starting it. I really think I can get it low enough to harvest, because I was a hair away from it last weekend before the rain came, and it should be dry here for a few days. Thanks so much for the help. Maybe next time I restart I'll slide a box trap over the inlet again. I have to admit I am almost dreading success because there is so much muck on the bottom. My wife thinks this whole project has made me even crazier than my usual. I'm like a man possessed draining this pond.
