Works have begun on four major levees to protect Carnarvon and surrounding areas from the threat of flooding.
In December 2010, homes, businesses and crops were severely impacted by devastating floodwaters.
The $60 million project will see barriers built at Nickol Bay, Lawson Street, South River Road and McGlades Road.
The Minister for Water, Bill Marmion, says the levees are designed to hold back a flood of a one-in-100-year magnitude.
He acknowledges there has been delays along the way but says the levees should be completed before next year's cyclone season.
"I guess like any project, there's priorities and I think it's probably fair to say that the devastation that happened in December 2010 and in the follow-up floods highlighted the importance of having some mitigation works in place to protect the important food bowl of Carnarvon," he said.
North-West MP Vince Catania says it is a bit of gamble the levees will not be ready for this year's season but the nearly completed Six Mile barrier should hold back floodwater.
He hopes the levees will ensure the December 2010 floods will never be repeated.
"We won't have that same scenario happen again to Carnarvon. Not only to the horticultural district but also to those residents who are also affected in town and not close the roads that also lead to the Pilbara," he said.
