Estuaries

What are estuaries

Estuarine ecosystems are highly complex and dynamic environments. Since estuaries are at the bottom end of catchments, their condition can be affected by activities occurring within the upstream freshwater catchment. Where the condition of catchments, rivers or estuaries is poor, there are likely to be additional impacts on the marine receiving waters and coastal areas. (Estuaries (water.vic.gov.au))

Many of Victoria’s estuaries close intermittently due to sand bar formation at the estuary entrance. This usually occurs during periods of low freshwater inflow. Intermittently closed estuary entrances are a natural feature of the Victorian coastline and can be critical to the ecology and physical form of estuaries.

The Regional Water Monitoring Partnership help monitor the flow of water entering the estuary and water quality conditions for estuary management.
