STRUCTURE BUILDING SYSTEM - The pickle barrel structure is a simple, low-cost means to improve bass-fishing habitat in a pond or small lake.  Made with a five-gallon plastic bucket, ready-mix concrete and hardwood tree limbs, the structure is anchored with a piece of angle iron.  Ray Scott's "Guide to Creating GREAT SMALL WATERS" illustrates methods for building and improving small lakes.  For information on the three volume video tape series, phone 1-800-518-7222.
