Water Minister Melinda Pavey has denied Shoalhaven City Council ever scheduled a meeting to discuss Lake Conjola with her.
This is at odds with a statement released by the council on the afternoon of June 5.
The statement said that Mayor Amanda Findley would meet with the Minister for Water, Property and Housing to plead the case for opening Lake Conjola.
A spokesperson for Ms Pavey said the mayor did schedule a meeting to discuss a separate issue.
However, Kiama MP Gareth Ward said he would take the meeting instead.
It is unknown at this time whether the meeting went ahead. Mr Ward has been contacted for comment.
Cr Patricia White praised the efforts of South Coast MP Shelley Hancock, saying Ms Hancock had worked tirelessly to bring the inundation at Lake Conjola to the attention of State Government ministers.
"Shelley's working to try and get an opening outside that policy," Cr White said.
"I'm not happy with how this has proceeded for the past seven months, as a council.
"Cr Guile asked the mayor what representations she had made to any minister, and she said she had talked to Shelley and was meeting with Minister Pavey on Thursday.
"We were under the impression that meeting was about Lake Conjola.
"It's the first time that formal presentations would have been made.
"I've learnt today that it was actually a meeting organised by [Kiama MP] Gareth Ward about homelessness, and the mayor intended to bring Lake Conjola up.
"That's not good enough."
