This shows the bank cover with the quarter log attached to the edge to keep the rocks from sliding off. The water will scour under this bank cover providing a deeper cover for the trout to hide. It provides protection from the birds such as kingfishers and herons. Large branches and small logs are placed under some bank covers to provide a place for fish to hide so the otters cannot get them. The brances are placed so that the fish can get behind them, but the otters cannot get through them.
