Are you a water sport person? The man-made pond will be large enough for you to roll your boat. If you are patient enough, you can do some fishing. If fishing is not your cup of tea, you can try catching some yabbies.
Children needs to be supervised at all times and we don’t encourage anyone to go for a swim or dive in the pond. The children however will find lots of fun even just throwing small rocks over the tranquil water.
