The Tronoh Dredge Hole was created in the mid 20th century when a section of the Ovens
River East Branch was cut off from the main river course to dredge it for gold. The hole has
filled up with water to create a small lake. It was enhanced as a swimming destination by local volunteers,
who have since added a quirkily named jetty and a floating swimming pontoon. The lake is nestled in amongst a mix of tall native and European trees,
with walking tracks around the edge of the lake and through the surrounding forest.

The lake has been plagued by algal blooms in recent years, primarily due to the lack of throughflow. On my last visit there was a noisy pump
working away in the far corner of the lake, trying to push through some fresh water. Despite the best efforts of the pump, there were
still several large mats of algae floating on the leeward side of the lake.
I hope that the efforts to eliminate the algae are successful, and
that this swimming hole can be restored to its former glory. There is a second lake to the north of the jetty that is connected to the main dredge hole,
but this smaller lake was quite stagnant and is not suitable for swimming.

As a dredge hole, the banks of the lake are quite steep, and the water depth increases quickly away from the shore. Therefore, this swimming
spot is best suited to experienced swimmers who can tread water without needing to stand up.
Even if you decide not to get into the water, this picturesque spot is worth a visit for a walk through the surrounding forest trails or for
a picnic with a view of the lake. For anyone with an interest in geomorphology, the nearby Ovens River East
Branch is eerily straight, presumably because the river bends were taken out by the dredging activities.
This swimming hole did not make it into my top 50 in Victoria because of its recent history of algal blooms. There is a lesser known swimming
hole in the nearby Ovens River East Branch that did make it into my top 50. If you want to know where it is, grab a copy of the guide to
Freshwater Swimming Holes in Victoria.
