Cherry Lake is part of historical coastal wetlands in Altona, a suburb of Melbourne, Australia. The wetlands were converted to a lake with construction of retaining walls, levees, and flow channels. The lake and surrounding reserve is an important wildlife habitat and popular recreational destination.
Cherry Lake and nearby Truganina Swamp are habitat for the native sedge, chaffy sawsedge (Gahnia filum). The sedgefields provide food and habitat for the endangered Altona skipper butterfly (Hesperilla flavescens flavescens).
The lake and associated salt marsh vegetation provides habitat for pelicans, black swans and purple swamphens.
Weed control is carried out on a regular basis, targeting spiny rush, serrated tussock and boxthorn.
Mosquito larvae numbers are monitored and a biological agent is occasionally utilised for control. Rabbit control is also undertaken.
The lake was created in the 1960s as a flood retention basin for residential expansion in Altona and Brooklyn. Prior to this, it was a motor racing circuit, constructed in 1954 at a cost of 35,000 pounds.
Levees were constructed on the south and east side of the lake with a spillway and channel which discharges excess water to Port Phillip Bay. These help to maintain a relatively constant water level of around one metre in depth. An additional higher levee bank was constructed to prevent floodwaters from Kororoit Creek sweeping across the lake toward residential areas.
