The new structures, known as “Georgia Cubes,” arecube-shaped and 3 feet tall, 4 feet wide and 4 feet deep. More than 50 feet ofcorrugated pipe will be stacked and woven into the PVC frame, allowing thestructure to attract and hold fish while keeping a fairly open design.
“We wanted to do something that wouldn’t be obtrusive to people using theirnice bass boats, so instead of using cinder blocks, we poured about 16 poundsof gravel in the PVC frame on the bottom to anchor the cube,” Sowards said ofthe anchoring system. “We’ll see how it does in extreme conditions but itshould hold them down.”
