Quarry Reserve, Ferntree Gully
Swimming Hole Heaven in Melbourne

This former quarry in Ferntree Gully is deep, cool, and protected from the wind, making it a popular swim on hot days, but with sometimes poor water quality. Swimming at Quarry Reserve, Ferntree Gully Above: The quarry wall looming over the lake at Quarry Reserve (Order this image)

As a general rule, with few exceptions, I avoid swimming in old quarries. However I put aside my misgivings to get in the water here on a couple of separate occasions, and will share the positives of this swim first. At over 200 metres long, this water body is large enough for a decent swim, and can cater for a large crowd on hot days.
Because the water level is well below the surrounding landscape, with a descent that resembles the start of the journey to the centre of the earth, it is well sheltered from any strong winds. Entry into the water at the northern end is only moderately steep, allowing swimmers to walk in rather than having to swim straight away. I have seen people of all ages loving this place, with teenagers doing (not permitted) tricks into the water from the wooden platform, and older swimmers sitting in the water, taking a cool bath. Inflatables can be useful for spending time in the deeper water, away from the shore.

Now for the reality check. Like most quarries, with no surface water outflow, the throughflow of water here is poor. This results in poor water quality, and poor visibility in the water. This has led to the council recommendation on site of "swimming not advised while Knox Council develops a water quality plan" and that the lake "may not be suitable for swimming at this time".
Council even advise to keep your dogs out of the water. When I swam here in early summer, when conditions had been cooler for several months prior, the water was fairly clear, with no visible signs of algae. However when I swam here in late summer, prior to the warning signs going up, there was a distinct green tinge to the water, suggestive of algae in the water column. Signs now added on site advise that blue-green algae may be present at times. On that basis, whilst I have swum here, I do not recommend it, at least until the local council has completed its water quality plan.

If you decide to not swim, it is still a pleasant spot for a walk with your dog or a picnic. The facilities are relatively new, including the playground, and the lawns are well maintained with views of the water. The dozens of steps also offer plenty of opportunity for some exercise.

Below is a quick video of swimming in the lake at Quarry Reserve, which gives my perspective on the distance from the car park down to the water, and an extrapolated interpretation of the council sign that was on site during this swim.
