Rockhampton Regional Council will open the Fitzroy River Barrage gates this week to clear aquatic weeds built up after recent rain.
Water Councillor Edward Oram said the release will commence tomorrow morning and be carried out across several days.
"After heavy rain periods, we see a build-up of water weeds in the Fitzroy, and it's important to flush the weed downstream while there is sufficient flow in the river," Cr Oram said.
"The release will be managed by raising two or three barrage gates at a time to increase the velocity which will draw the weed through.
"The release might take several days and will only occur during daylight hours to allow the released weed to be shifted downstream."
Council is urging boat owners to remain alert during this period.
"We ask boaters to exercise caution as weeds drift downstream, regularly check moored vessels for weed build-up, and take care when launching," Cr Oram said.
