This may be the site of Australia’s “dirtiest” power station, but the carbon counters cannot deny
that up until its closure in 2017, it was also the only large scale, public, outdoor warm water
recreational venue in Victoria. The water in the pondage was kept at a very pleasant 22 degrees
celcius all year round by circulating through the power station to cool the plant. That meant
you could even swim here in mid-winter.
Now that the plant has closed, groundwater is still being pumped into the lake from the base of the coal mine, which
keeps a narrow section of the lake warm. Unfortunately this warmer water is inaccessible to swimmers. You can still
swim in the pondage, but without the warm water, this brown and murky water is much less appealing than it once was.
Prior to the closure in early 2017, the warm water made the pondage popular for a range of events including
the World Masters Games, the Australian Open Water Swimming Championships and the Latrobe City Sauna Sail.
There is a caravan park at the south-west corner of the pondage, which has a poorly defined
and shallow swimming area. Along the western edge of the pondage there are a number of boat and
jet ski ramps which have deeper water for easier entry to the pondage without getting your feet muddy.
Here is a video that I took of a swim at Hazelwood Pondage on a chilly day in mid-winter, which
is now destined for the annals of history. On that particular day, I was the only one silly enough to
get into the water and was pleasantly surprised.
Essential Information Before You Go:
Yinnar Rd, Morwell, Victoria, 160 km (approx. 2 hrs drive) south east of the Melbourne CBD
From the Princes Hwy at Morwell, take the Monash Way exit and head south.
Turn right at the Hazelwood Pondage sign at Brodribb Road.
Previously warm, now mild to cool.
Shade available out of the water
Facilities, conditions under foot in the water, maximum water depth, minimum swimming proficiency required, and
prohibitions including whether you can bring your dog: Order the full guide
Potentially at the caravan park with some assistance
Unpowered sites are available at the Hazelwood Pondage Caravan Park. The caravan park doesn't have a
website, so you need to ring them up to book. Alternatively, you can try
accommodation near this lake.
Powerworks Museum, the Morwell Rose Garden in town, and for swimming, Lake Narracan
15 km to the north.
Before you head out, make sure to read the
swimming safety information.

Change of Conditions:
It's official: Hazelwood Power Station began shutting down in March 2017. The future of the pondage
is unclear, but early indications are that the mine void itself might be turned into a recreational lake. It is unknown
whether this will involve swimming, or just passive recreation.
Barramundi were stocked in Hazelwood Pondage in 2016 as part of a plan to
encourage recreational fishing at the pondage. This decision was made before the announcement that the power plant would close.
Barramundi are a tropical fish and only survive in warm water. I have been
swimming with barramundi in the Northern Territory
and they were quite comfortable around swimmers, inquisitive
but non-aggressive, and did not interfere with your swimming. Media reports in mid-2017 indicated that large numbers of fish
perished when the weather turned cold in the winter of that year, but most survived by moving towards the channel where the
warm groundwater is still being pumped into the lake. According to
The Fish Vet's blog
Barramundi start to get sick when water temperatures are in the mid-teens, and mortality has been observed in fish farms when the
water temperature dropped to 11 degrees celsius. From local monitoring data, water temperatures in Victorian streams
drop to below ten degrees on cold nights in winter, which is why you can't find barramundi elsewhere in Victoria.

experiences after visiting, and any changes in swimming conditions. I received a range of great questions leading up to the
power plant closure, which I responded to and published, but have since removed given that closure has now occurred.
