The quarry was eventually converted to a swimming hole, where regular swimming competitions took place but was decommissioned in the 1970’s when it became unhygienic as a swimming facility. The majority of the hole depth was filled in and is now only 1-1.5 metres deep. The area is now well utilised by the general public and the model boat club.
