I have made a couple of bamboo brush piles in a small lake and they worked good for about a month. I caught a some crappie not even a week after they was out. Then I went back to fish them about a month later and couldn't even find them on my fish finder(Lowrance HDS5). Has anyone ever tried this in a pond or had this happen to them. I was thinking about making one in my pond and looking for some ideas on how to make them?
