"We monitor the lake levels and weather forecast closely once the water level approaches the trigger for opening," MidCoast Council water quality and estuary co-ordinator, Prue Tucker said.
"At this stage predicted weather conditions do not warrant an opening," Mrs Tucker said.
"With predicted wet weather for the coming months, it is very likely that an opening will be required in the near future."
Smiths Lake is known as an intermittently closed and open lake or lagoon.
"This type of lake naturally opens to the ocean in response to water levels in the lake and they close as a result of sand movement from waves, tides and wind.
"Smiths Lake is opened manually to prevent minor flooding of property and roads in an environmentally sensitive way."
The lake is opened at the established 2.1 metres trigger or when the trigger is predicted to occur during a forecast major rain event.
With predicted wet weather for the coming months, it is very likely that an opening will be required in the near future.

Today, Monday, September 20 the lake is measuring 1.86 metres.
"The exact timing and level of any opening is influenced by the prevailing weather conditions and tides," Mrs Tucker said.
In planning an opening, council must consider the best conditions to maximise the health and productivity of the estuary and ensure there are high lake levels to maximise scour of the entrance.
The lake was last manually opened in July 2020.

"We're encouraging residents and visitors to monitor lake levels and our website for notice of the lake opening and make plans to remove your vessels from the lake so they are not stranded when it is opened."
