Borumba Dam is located just south of Gympie and stores water for drinking as well as irrigation as part of the Mary Valley irrigation scheme.
Built across Yabba Creek, the Borumba Dam was originally completed in 1963 and upgraded in 1997.
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 Borumba Dam begins to spill, please sign up to our free dam release notification service.

Lake Borumba is located near Imbil, just south of Gympie. The lake has a catchment area of 465.0km2 and holds 45,952 megalitres of water at full supply.
The primary purpose of Lake Borumba is to provide water to the Mary Valley irrigation scheme.
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 Borumba Dam, this is Gympie Regional Council.
