The maps of flood-affected towns including Emerald and Theodore can be found
Users can type in their address or the address of someone they know and see where their property is in relation to the city or town flood line.

2010-2011 Natural Disasters mapsThe 2010-2011 Natural Disasters maps are a useful tool for seeing street by street which areas were affected by inundation in the summer of 2010/11.
Sources of Information
The Interim Flood Line has been mapped using ultra-high resolution aerial photographs (where available) using the visible debris line, in combination with council and community feedback.

Queensland Floodplain MappingThe Floodplain maps show areas of Queensland where, based on geological evidence, we know there has previously been inundation or there is a probable chance of inundation.
The Floodplain maps are supported by the Planning for stronger, more resilient floodplains guideline. The guideline provides Councils – especially those who have perhaps historically lacked the resourcing capacity to undertake these types of studies - with a ready-made toolkit to help assess future development applications and the opportunity to better align floodplain management and land use planning.
Sources of information
The Interim Floodplain Assessment Overlay Mapping has been derived from overlaying available state-wide information sources, including best available:
- Drainage location information
- Contour information (typically 10 metre contours)
- Satellite imagery (typically Landsat 5)
- Interpreted or actual flood information from 2010/2011 events
- Department of Environment and Resource Management gauging station information
- Pre-clear Vegetation Mapping of Landzone 3 (Alluvium) and Landzone 1 Estuarine and SALI Soil Flooding Limitation Mapping
Completed / Uncompleted Areas of Floodplain MappingGiven the size of Queensland there are areas where the mapping is still being produced. The Authority has established a programme to develop the floodplain maps for the entire State and release them as they become available.

PDF versions and imaging.The Authority has produced maps that compare aerial footage of disaster affected towns and cities using before and after imagery. This list of towns and cities will be added to progressively. You can also view the interactive map to see more details about the disaster-affected areas.

ARTICLE FROM 2011
Old-timers on a high when water levels rose
January 5, 2011
Not for the first time while in Queensland, I have pondered, "how did they get a planning permit for that?" And, "no wonder they can't get insurance coverage" or "it's not surprising everybody's insurance premiums up here have been increasing over the last few years".
Rockhampton braces for flood peakResidents are preparing for the worst as the flooding in Rockhampton is expected to peak on Wednesday.
Very recent history is repeating itself. I noted during the January 2008 floods in Emerald, all the brand new, low-set houses that had been allowed to be built on clearly flood-prone land. And now they're under water - again.
Sometimes, there might be historic or cultural reasons for such decisions but it is usually "good practice" to require minimum standards such as ensuring floor levels are at least two metres above ground level.
Many older-style houses up on stilts are taking the current floods in their stride. This is the practical and sensible design approach of our parents and grandparents who knew there would be no one coming to save them in a "Big Wet".
Our mothers and grandmothers knew how to plan ahead, keeping a watchful eye on unseasonal wet weather from August to November (which is precisely what we have had up here) and stocking up. In those days it was powdered milk, tea, sugar, flour and preserved fruit and meat, and a stockpile on high and dry land of cut timber for the stove. The rainwater tank was on a strong elevated stand of hardwood timber we can only dream about these days (such tank stands have been demolished or left unused in recent years, deemed unsafe).
Nowadays, with all the low-set homes, it seems there is a lack of good planning from Central Highlands Council, which covers the waterlogged town of Emerald.
And the same can be said of Bundaberg and Mackay regional councils, both towns having been built on river deltas or floodplains. The lessons should have been learnt from the big floods of the early 20th century.
Despite the Bowen Basin mining boom, the region still desperately lacks infrastructure. Moranbah and Clermont, a couple of hours' drive north of Emerald, want to become permanent and sustainable communities but lack a reliable water supply for a growing population.
It must also be remembered there has been an enormous amount of tree clearing over the decades and this has reduced absorption and had an impact on the speed at which floodwater flows. As a result, it is not fair to blame nature alone for the devastation.
It is also a bit rich to claim this is a tragedy of biblical proportions.
Yes, some areas are seeing the biggest floods in 50 or 60 years but in Rockhampton, where upstream flood levels have begun to fall, it is still barely a one-in-20-year event.
The mighty Fitzroy Basin takes in the Dawson, Mackenzie and Isaac rivers and related tributaries and feeds and drains an enormous area. Some of this land is quite marginal and some of it ideal for cropping and grazing cattle.
Right now, and with the greatest respect to those who have had to evacuate their homes, nature is just doing what is entirely predictable and it's a largely beneficial thing.
As well as overland flows, there will be a lot of water seeping into the ground across potentially productive land, not just along rivers and creeks. To follow the calls for a huge dam construction program could well jeopardise this great benefit.
However, I must confess, I am inclined to support building a decent moat/channel around Emerald, which would lead to a new dam to support the water needs for agricultural and mining towns to the north such as Capella, Clermont and Moranbah.
What about getting the mining companies to start paying their way in the dam infrastructure stakes?
It's a pity that over the past decade in particular, some councils and communities have chosen to ignore the numerous lessons of the past three to 50 years about where not to build.
If you must build houses here, councils should insist they be on stilts.
