Latest news
The Sydenham Inlet opened naturally to the sea on Thursday 24 April 2025 following rainfall in the catchment.
Pattern of closures
Sydenham Inlet is a large open shallow body of water with a short, narrow channel to the ocean. Once closed, the estuary rarely opens naturally.
Location of flooding
Flooding occurs on roads, wharves and boat ramps.
Level required for a successful opening
The entrance opening level has been set historically at a point where inundation of farmland protected by levees is reached. This level is 1.65m. These levels can be determined by viewing the gauge at the boat ramp.
Water height levels are found on Victoria’s Water Measurement Information System. These measurements are taken from a gauge at Sydenham Inlet. Other Data is collected including salinity, stream water level and water temperature.
Responsibility for an opening
Parks Victoria coordinates the works component of the opening which is approved by East Gippsland CMA.
