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.
Pattern of closures
The estuary closes frequently, between one and four occasions each year.
The duration of the closures typically ranges between three weeks and seven months, although the average is under two months.
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.
Responsibility for an opening
Parks Victoria coordinates the works component of the opening which is approved by East Gippsland CMA.
