A 3ft tall AquaDam was used to form a perimeter, the center of which was lined with extruded Polyethylene film, to form a watertight pool/pond area. The water-filled pool was a great addition to the Dogapalooza; Dogs were able to jump from the launch platform into the water, or onto the AquaDam, with no injury. The water simply absorbs the energy. The pool was installed in about 4 hours, and removed in about 6 hours time. Thanks to everyone who participated to make this happen!
