Collie will see another summer without access to Lake Kepwari as the opening is again delayed due to "additional complexities".
The redevelopment of the old mine pit into a major water sports destination has been in limbo for the past 11 years despite election promises in both the 2008 and 2017 state elections.
The WA Labor Party promised locals they would have the state's biggest freshwater lake in the 2008 state election and again in 2017 it promised the completion of the lake within six months.
However, despite more than $3 million committed to the project the lake remains closed, dogged by water quality concerns, safety concerns and red tape.
In August this year Premier Coal announced the completion of inlet works and the first water flow through the diversion channel breach following rehabilitation works.
According to Premier Coal the company's intention was to submit an application to surrender the site from its mining lease once the inlet and diversion channel breach area works had been completed.
Collie-Preston MLA Mick Murray said additional complexities had occurred during the rehabilitation process which has now led the site handover being stalled.
"I've been caught out in the past putting a timeline on this project so I cant say when the lake might open to the public at this point but rest assured I will be one of the first ones in when it does," he said.
"It is my understanding that the (Department of Biodiversity, Conservation and Attraction) and Premier Coal are continuing to work towards an agreement which will allow the department access to part of the site while the company continues the next stage of its rehabilitation works."
Mr Murray said the department's tender process for the construction of the board ramp, car park and other elements of day use facilities was open with prospective contractors due to visit the site.
Regional Development Minister Alannah MacTiernan echoed Mr Murray's sentiments confirming the lack of opening this summer.
"Significant rehabilitation work has been required on the area with public safety being a primary consideration," she said.
"Given that time frame, it is unlikely the facilities will be ready for the coming summer."
