I just sank a bunch of branches in about 10 to 15 foot of water. The first one i sank i left the rope to long and the tops floated to the top. The next night I had to go down to the lake and get something and I shined my light into the water and the darn beaver was swimming away with some of the limbs. There really starting to piss me off. I just hope there not getting all the other ones.
