WATER has been released from Lenthalls Dam for a second time since earlier this week.
Wide Bay Water Corporation executive manager Denis Heron said the dam's gates were opened on Wednesday at 1pm and are due to close Thursday at 7am.
"The dam's gates have been opened to make releases to meet the Resource Operating License conditions under the "high flow" rule," Mr Heron said.
Operations staff and dam rangers are monitoring the dam's water level along with a SCADA system which reports to WBW's computer network, he said.
At about 3.30pm Wednesday, the water level at Lenthalls Dam was 26.04m, equal to 100.1%.
About 8mm of rain was received over Lenthalls Dam in the 24 hour period up to 9am on Wednesday morning, with about 6mm received at Musket Flat, a catchment for the dam.
"No rain has been recorded at both sites since 9am," Mr Heron said.
"(The) 35 people including Esther Allan, with property in the affected area have been contacted with regard to the EAP (emergency action plan) and environmental release of water from Lenthalls Dam. Please note not all people that are contacted reside in the area on a permanent basis including Esther Allan," he said.
Ms Allan's Doongul Creek property, upstream of Lenthalls Dam, has been flooded multiple times since Lenthalls Dam's water storage height was increased in 2007.
In 2011, she submitted evidence to the Queensland Flood Commission of Inquiry after her property was flooded earlier that year.
