The southern end of the lake is close to State Highway 6, while the western side is bordered by Slope Hill. The main area for access to the lake is the northern end which has a large grassed area for recreation activities.
The Lake Hayes Showgrounds which have a pavilion and parking area has an annual show called The Lake Hayes A&P Show.
The nearby large residential sub-division of Lake Hayes Estate is just across the main highway and takes its name from Lake Hayes.
Settlers originally knew the lake as Hays Lake after D. Hay, an Australian who came to the district looking for sheep country in 1859. Its name gradually changed to Lake Hayes, as its discovery was credited erroneously to Captain "Bully" Hayes, an early local character of the district.
