NSW State Emergency Service has issued a flood evacuation warning for some residents in Lake Conjola.
As a result of rising flood waters residents within the Lake Conjola Entrance Tourist Park, Deep Water Resort, Edwin Avenue, Aney Street, Milham Way, Gerrard Way, Carroll Avenue and Lake Conjola Entrance Road should prepare to evacuate within the next two hours.
Residents are advised to go and stay with family or friends, or make other arrangements. An evacuation centre has been set up at the Ulladulla Civic Centre.
SES advises that once floodwaters hit 1.5 metres, road access will be cut. You may become trapped.
An Ulladulla SES Unit spokesperson said a flood rescue crew is stationed at Lake Conjola and they have a presence on the ground. Other crews continue to do reconnaissance work at Burrill Lake and Lake Tabourie.
Shoalhaven City Council has advised residents of Shoalhaven Heads and Lake Conjola that there will be a mechanical intervention at each of these locations today.
Council will open Shoalhaven River entrance and Lake Conjola's entrance to the sea.
"People are requested to stay outside the work area and keep away from the edges of the dug channel and eroding banks following opening as these areas are very unstable and unsafe. It is expected that the low-lying areas around the lake will be subject to flooding and people should put in place their flood emergency plan."
More than 100mm has fallen in the Milton-Ulladulla district since 9am on Sunday. SES advises people should stay clear of driving through floodwaters.
