The lake was originally part of a natural wetland system but was significantly modified in the 1960s to serve as a flood mitigation basin for the Altona industrial area.
The reserve acts as a critical 'stepping stone' for migratory shorebirds moving along the East Asian-Australasian Flyway.
Water levels in the lake are managed to support a specific ecosystem that discourages invasive species while fostering native aquatic life.
The park's diverse bird population frequently includes the rare Australasian Bittern, which relies on the dense reed beds for cover.
Cherry Lake Park is a 45-hectare wetlands and recreation reserve located in Altona, specifically designed for both wildlife conservation and community outdoor activity. The centerpiece is a large, permanent saltwater lake surrounded by a 3.7-kilometer shared-use trail suitable for walking, jogging, and cycling. The park serves as a significant regional habitat for over 150 bird species, including migratory waders and Australian pelicans. Visitors can access multiple picnic areas, electric barbecue facilities, and a playground located near the eastern shore. The site features extensive re-vegetation efforts involving indigenous flora to manage water quality and support local fauna. A dedicated outdoor exercise station is situated along the main circuit path.

Bring high-quality binoculars, as the best birdwatching spots are located in the quieter, southern sections of the trail.
The path is fully exposed to the elements, so carry sunscreen and adequate headwear regardless of the season.
Keep dogs on a leash at all times to protect the ground-nesting bird populations.
Do not attempt to swim or wade in the lake, as it is a managed stormwater catchment and not intended for primary contact recreation.
Stay on designated paths to protect sensitive wetland flora and avoid disturbing nesting sites near the water's edge.
