Lenthalls Dam received about 8mm of rainfall in the 24 hour period up to 9am Wednesday morning, according to the Bureau of Meterology.

AS LENTHALLS Dam reached "minor flood" levels early Sunday morning, Esther Allan's safety was put at risk due to an alert blunder.
The Doongul Creek woman, along with 34 others who live near the dam, should have received a text message as soon as the dam's water height reached 25.7m at 4am on Sunday morning.
But in a mistake admitted by Wide Bay Water Corporation executive manager Denis Heron, not one resident was notified at the time.
While the other 34 property owners were messaged the vital details four-and-a-half hours later, including the dam's water level, rate of rise and the status of the flood gates operation, Ms Allen was kept completely in the dark.
"People like me are supposed to rely on these people (and) I shouldn't have to sit on high alert continually when there is a storm in Hervey Bay," Ms Allan said.
Mr Heron said Wide Bay Water Corporation would now "endeavour to improve our systems" after the alert botch-up.
"Esther Allan was not included in the group SMS sent out on Sunday, and should have been in the SMS group," Mr Heron said.
"The error was picked up on the following day which resulted in the telephone call to Esther Allan on Monday. It should be noted that rapid rise of water in the early hours of Sunday were not foreseen hence the delay in the notification to the property owners."
A severe supercell storm battered the Fraser Coast from Friday, bringing a downfall of about 146mm onto Lenthalls Dam's catchment areas between January 29 and 31.
Despite the communication mistake, the floodgates worked, after millions-of-dollars in repairs undertaken last year.
Gates two, three and four were opened in sequence from 7am on Sunday with the last closed by 4.45pm on Monday, with gates one and five tested.
"It is also pleasing to note that the gates operated to their design following their recent upgrade," Mr Heron said.
Ms Allan's property has flooded multiple times in the past due Lenthalls Dam once malfunctioning gates.
In 2011, she submitted evidence to the Queensland Flood Commission of Inquiry after her property was flooded earlier that year.
