Swimming enclosure with large number of items lost, carelessly controlled and deliberately dumped

bicycles - deliberately dumped

plastic beverage bottles - used heavily in this area but too prone to easy loss and inconvenient to reomve and dispose of environmentally respectfully

towels and swimming garments - these are unlikely to be dumped but numbers are considerable and whilst may provide some habitat could affect the natural covering of the seafloor
