Council making moves to open Lake Conjola
November 29, 2011
Shoalhaven City Council has begun preparing for an opening of Lake Conjola as a result of the recent rainfall having an effect on water levels.
Council’s staff has been monitoring lake water levels following the weekend’s deluge of rain which already resulted in minor low level flooding of foreshore land following the saturation of the catchment area.
As a result of the recent rain, the water level in the lake has reached 0.8m Australian Height Datum, still just short of the 1.0m AHD level that triggers mechanical intervention to open the entrance.
While some members of the community have indicated a preference to open the lake at the 0.8m level, Council is yet to consider recommendations from a review of the Entrance Management Policy meaning the trigger level of 1.0m AHD currently remains in place.
With an increase in rainfall expected later in the week, Council staff have authorised the preparation of a pilot channel as soon as the contractors machinery can be deployed.
The pilot channel will enable the area to be ready for an opening once tidal conditions are suitable and the trigger level has been reached.
Discussions with National Parks and Wildlife staff have confirmed the presence of Pied Oyster Catchers in the area, with Little Terns also expected to be nesting on the spit.
To minimise impacts on the nesting area a northern pilot channel will be adopted.
The final opening of the Lake will remain dependent on rainfall intensity and ocean conditions.
