The Member for Burdekin says it is very alarming that the Don River broke its banks in areas that were previously seen as "safe".
The Bowen region received significant rainfall as Tropical Cyclone Ita moved down the Queensland coast.
Rosemary Menkens says a number of farms have been destroyed because a build-up of silt and undergrowth prevented water from moving downstream.
She says while it is not an easy problem to solve, moves must be made quickly.
"It'll be very disappointing to see another flood season come through without proactive measures being taken to alleviate the silting," she said.
"This flood that we've just seen was not the highest flood.
"If that was a much larger flood that would really really be disastrous.
"Breaks have occurred in areas that have never seen breaks before and the community is concerned because the Don River runs next to Bowen - we see the suburb of Queens Beach right [next] to the river and it is very, very concerning seeing this build-up of silt."
She says she is confident Government ministers will support any application to dredge sand and silt from the Don River.
