The dam wall is one of the largest earth-fill dams in Australia, measuring 85 meters high.
The reservoir is a primary water storage facility for Melbourne, capable of holding 287,000 megalitres.
The park was designed to incorporate water catchment protection alongside public access through careful zoning.
The reservoir serves as a critical junction for the Melbourne water supply system, receiving water from the Upper Yarra and Thomson reservoirs.
The site hosts a significant population of eastern grey kangaroos that are largely habituated to human presence.
Cardinia Reservoir Park serves as a major water supply catchment for Melbourne while providing extensive recreational space. The primary feature is the massive earth-fill dam wall, which allows for expansive views across the reservoir and the surrounding bushland. Visitors can access a network of walking trails, including a track that crosses the crest of the dam. The park is home to a resident population of eastern grey kangaroos frequently seen in the designated picnic areas. Native flora throughout the park includes eucalyptus woodlands and dense undergrowth. Multiple picnic sites are equipped with wood-fired barbecues and sheltered tables. The park spans significant topography, ranging from the reservoir waterline to elevated lookout points. It functions as a managed environmental area under the jurisdiction of Parks Victoria.

Bring your own firewood if you plan to use the park's wood-fired barbecues, as gathering wood on-site is prohibited.
Keep a safe distance from the kangaroos, as they are wild animals and can be unpredictable if approached.
Utilize the viewing platforms on the dam crest for the best vantage points of the water storage area.
Do not attempt to swim or use watercraft in the reservoir, as it is a strictly protected drinking water catchment.
The park gates may close early or remain inaccessible during periods of extreme fire danger or maintenance.
Keep dogs on a leash at all times and take all litter home; do not feed the local wildlife.
