Mount Bold Reservoir

Mount Bold Reservoir

Mount Bold Reservoir Reserve will be temporarily closed to visitors from Monday 4 May for around three to four weeks, while we use heavy equipment and machinery on site, as part of early investigative works for a dam safety upgrade.

The water level at Mount Bold has been lowered to enable this part of the project to be undertaken, and there will be an opportunity for the public to view a near empty reservoir from usual access areas, following the completion of the works.

Go to for details on other reservoir reserves open to visit in the meantime.

Mount Bold, the largest reservoir in South Australia, is about 45 minutes drive south of Adelaide and surrounded by more than 5,500 ha of land.

The reservoir is not directly connected to the water network. Water from Mount Bold is released as required to maintain an adequate level at the Clarendon Weir from where water is diverted to Happy Valley.

Capacity: 46.4 gigalitres (one gigalitre is one billion litres), which would fill more than 23,000 Olympic swimming pools

Public access: Yes, for details and opening hours visit

Mount Bold is closed to the public during ‘pre-release’ events – when the storage is at capacity and water is released to mitigate any flood and safety risks – as this water blocks the normal access route.
