Estuaries of the Corangamite region

An estuary is the area where a river meets the sea. Estuaries are unique and dynamic environments that include some of the most complex ecosystems on earth, and the Corangamite region has more estuaries than anywhere else in Victoria.

Estuaries are a great place to spend time swimming, walking, canoeing or having a picnic. Importantly, they also act as buffers to protect shorelines from erosion, flooding and provide essential food and habitat for birds, fish and other wildlife.

Fluker Posts are physical wooden posts that act as photo points installed at strategic locations in the environment. No camera is left on a Fluker Post. Instead, people walking past use the Fluker Post app on their own phone to take a photo of the given scene. This simple system of repeat photography provides a valuable long term natural resource management tool.

The Fluker Post Project is supported by Victoria University, the Department of Environment, Land, Water and Planning, and the Corangamite CMA.

Environmental releases can be targeted releases from a dam to meet the environmental needs of the downstream river ecosystems, such as releasing pulses of water in spring to trigger fish migration and spawning, or continuous low flows over the dry summer period to maintain water quality and connection between habitat pools. It can also be a watering action such as filling or draining a wetland from a river at the right time of year to enhance its ecology.

Passing flow is water that is required by law to be released from dams by water authorities to maintain some flow in the river downstream, as water is harvested from the river. Passing flow is separate to ‘water for the environment’ held in an Environmental Entitlement, but also helps maintain environmental values and other community benefits.
