The reservoir dam wall is 41 meters high and 377 meters long, containing over 1.2 million cubic meters of earth and rock.
The park's rose garden and structural landscaping were largely influenced by the 'City Beautiful' movement of the early 20th century.
The reservoir serves as a major component of Melbourne's water supply system, fed by protected mountain catchments.
The spillway is designed as a cascade, allowing water to flow over concrete steps during significant rainfall events.
The arboretum contains significant specimens of trees planted during the park's establishment in the 1920s.
Maroondah Reservoir Park is a heritage-listed parkland featuring expansive manicured gardens, native woodlands, and views of the massive earth-fill dam wall. The site was constructed between 1920 and 1927 to supply water to Melbourne and includes a large spillway designed to handle extreme overflow. The grounds incorporate an arboretum with exotic tree species and landscaped terraces inspired by classic European designs. Walking trails wind through the forested hills surrounding the reservoir, connecting to the broader Yarra Ranges region. The park is managed by Parks Victoria and serves as a critical infrastructure protection zone alongside a recreational space. It is a popular location for birdwatching, picnicking, and observing the reservoir's seasonal water levels.
