About Leslie Harrison

Leslie Harrison Dam, located on Tingalpa Creek, was completed in 1967 and upgraded in 1984 to increase its storage capacity.

Also known as Tingalpa Reservoir, Leslie Harrison Dam is part of South East Queensland’s drinking water supply.

It is an un-gated dam, meaning that when it reaches 100 per cent capacity, water flows over the spillway and safely out of the dam.

If you would like to be notified when Leslie Harrison Dam begins to spill, sign up to our free dam release notification service or download our public safety mobile app.

There are no recreation activities permitted at or on Leslie Harrison Dam.

  • Flood mitigation

    All dams help mitigate flooding to some extent. The peak outflow from a gated or un-gated dam during a flood event is less than the peak outflow that would have occurred had the dam not been built, because some water is held in the dam while it is spilling. This means that water flow slows down as floods pass through the dam.

    It’s important neighbours and people downstream of dams know what to do in the unlikely event of an emergency. Each of our dams have an emergency action plan (EAP) in place to enable us to respond quickly to potential incidents in partnership with the Bureau of Meteorology, relevant emergency services and local councils. For Leslie Harrison Dam, this is Redland City Council.
