Community leaders in the Boyne Valley, south-west of Gladstone in central Queensland, are calling for more flood gauges to be installed along the Boyne River.
The Gladstone Area Water Board operates two flood gauges upstream from the Awoonga Dam.
However, Frank McKee from the Many Peaks Rural Fire Brigade says because those two gauges are so close to each other, there was only limited information before homes had to be evacuated in the Boyne Tannum area during the January flood.
He says a flood gauge should be installed closer to the headwaters of the Boyne River catchment.
"If they were to get these gauges stations spread further up into a more relevant area now that the dam has been raised, that will give them a lot better idea of how much water is coming down, how elevated the levels will become," he said.
"If there is any evacuations to be called for in the lower reaches around the Boyne-Tannum area - they won't be getting half an hours notice, they might be getting four or five hours notice."
He says another gauge near Builyan would give authorities more time before floodwaters reach the dam.
"What I would like to see happen is one to be probably in very close proximity to where the Boyne River headwaters and the Glassford Creek headwaters actually merge at Boxvale, so close to Builyan," he said.
"That will give a good indication of there's a lot of water coming down past Builyan, there's a lot of water coming past Nagoorin, it will get to the dam shortly."
