The weather bureau is warning of flash flooding between Cairns and Innisfail in far north Queensland, as a monsoon trough dumps heavy rain across the region.

Forecaster Bill O'Connor says the heavy falls are expected to continue this morning.

"Mainly for those people down through the Goldsborough Valley, Gordonvale, south of Edmonton - there's going to be a continuation," he said.

"Watch out for some of the rainfall, watch out for any creek crossings, river crossings,

"Peet's Bridge, for example, it's still below the bridge at the moment but I wouldn't be surprised if during this morning we see that sort of trickle over the top of the bridge, down through that area."

He says Babinda has been the worst affected area so far.

"The highest rain we've had so far is 398mm since nine o'clock yesterday down at the Boulders," he said.

"Got a severe weather warning out for Cairns area and heading south basically down to Innisfail but we've seen lots of totals above the 200mm mark overnight."

Rainfall from ex-tropical cyclone Dylan has caused the Eungella Dam to overflow, west of Mackay in north Queensland.

The dam filled to capacity yesterday and water is now flowing over the spillway.

Energy and Water Supply Minister Mark McArdle says the dam's operator, SunWater, has activated an emergency action plan for Eungella.

SunWater general manager Tom Vanderbyl says the dam is designed to store water to capacity with any excess inflows to be diverted through a purpose-built spillway.

Mr Vanderbyl says Eungella Dam is being operated in flood mode and residents immediately downstream, the local disaster management group and the police have all been notified.

At this stage there have been no reports of damage to properties or flooding of roads.

One of life's great questions is about to be answered... "What's going on below the surface of the Noosa River?" That would be the baffling question I'm sure we've all pondered for hours. Yes, I see you nodding as you read. Well, don't worry, the Noosa Underwater Biodiversity Assessment—the NUBA—has begun its mission to find the answers.

http://www.underseaproductions.com/

Following the "think global, act local" mantra, my life's ambition to film every fish in the Indo-Pacific (formally, the planet) has followed me home to the Noosa River.

Why film every species in the Noosa River? Would anyone even care? I reckon the reason people don't care much about what's underwater is that they never learned about it in school, and they can't see it for themselves as they walk the dog on Gympie Terrace. Yet, I've rarely shown underwater footage without getting a "Wow, what's that?"... with a further "And what's that?" to my reply. The nudibranchs and ascidians and other mysterious critters that live in every square inch of underwater habitat are fascinating to learn about and observe. And since I've never seen any of the thousands of annual visitors or residents of Noosa scuba diving in the river (although I'm sure they are out there and I'd love to hear from them), I have to assume that most people don't get in to see it firsthand. So it's up to me to bring the vision up to the surface. To give a voice to my unseen little aquatic mates. To help my fellow fishermen have greater fishing success while leaving a smaller impact. To raise awareness with the locals and foster community-wide stewardship of the river.

Once we know what we have, and combine that with research into what we used to have (through historical fishing and other records), then we can begin to bring our river back to its former glory. Which means a healthier river and coastal ecosystem, with more and bigger fish for everyone. That's my goal for every community, starting with my own.

Since moving to Noosa, our local diving efforts have been somewhat limited, mostly due to the closure of both dive operators and the unusually poor visibility from flooding that hit Queensland in recent years. However, select days over the past few months have provided some filming opportunities: when the moon and tides and winds combine to create those magic Noosa River days where kayakers and outriggers can see the river bottom over vast stretches of shallow seagrass and sand bars teaming with... what exactly? Not sure really. Flathead, whiting and bream... but what else?

Generations of fisherfolk and visitors know and proudly show what we can catch here, but there's more to the system than that. What about the stuff that doesn't take the hook or get caught in the net? Those other creatures that are quietly working away to keep our river ecosystem ticking nicely along?

This little highlights video shows some of what I've found so far, almost all filmed at the river mouth car park rockwall. My species count to date is 102 (73 of them being fish).

I'm fairly confident I can film the majority of the 122 previously recorded fish species, and most likely come up with at least a few more. I'll be keeping the stats with links to the footage of each species updated on the NUBA webpage as the project progresses:
http://www.underseaproductions.com/no...

This is a long term project that I hope will involve a wide range of river community groups, schools and businesses. My initial presentation to the Noosa Integrated Catchment Association (NICA) was enthusiastically received, and I'm looking forward to speaking to other members of the community over the coming months.

URBANISATION, habitat degradation and waterway barriers have led to decreased numbers of native fish in NSW waterways in recent years, but programs by the Department of Primary Industries (DPI) have worked on restocking fish in these areas.

Native fish fingerlings ready for release.

Native fish fingerlings ready for release.

Under constant threat of having their habitat destroyed, native fish have needed a helping hand from organisations such as the DPI and Landcare to increase numbers as well as improve recreational fishing opportunities.

NSW DPI fisheries management officer Ben Doolan, Nelson Bay, said close to three million trout and salmon and two million native fish, produced by government and private commercial hatcheries, were stocked into inland NSW waters each year.

“There are four species of salmonids, which are rainbow trout, brown trout, Atlantic salmon, brook trout, and four native species, which includes Australian bass, golden perch, Murray cod, silver perch, stocked for recreational fishing,” he said.

“Trout cod and Macquarie perch are stocked for conservation purposes to aid in the recovery of those species.”

Typically, four hatcheries provide fingerlings, also known as fry, for restocking.

The Port Stephens Fisheries Institute hatchery produce Australian bass, which are released into major impoundments along the east coast including Glenbawn Dam, Glennies Creek Dam and Lostock Dam in the upper Hunter Valley, Tallowa Dam near Kangaroo Valley, and Lake Wallace and Lake Lyell near Lithgow.

Mr Doolan said during restocking seasons, which varied for each species of fish, there were no restrictions for recreational fishers.

“We aren’t usually too concerned about recreational fishers being in the vicinity of newly released fish,” he said.

“The fry or fingerlings are not susceptible to recreational fishing due to their size and are mobile and will find suitable habitat.”

However, closed fishing seasons for some species have been implemented to reduce pressure or interaction with mature fish during times of spawning.

“Some species are closed for a period of time during the year, however trout cod and eastern freshwater cod are protected all year round and must be released if caught,” he said.

“There is a closure on all forms of fishing in the Murray River between Yarrawonga and Tocumwal for added protection during the (trout cod) breeding season and throughout the Mann River and some of its tributaries during August and October for eastern freshwater cod.”

Mr Doolan said these closures were primarily implemented to protect the adult fish, although the trout and salmon closure protected juvenile trout as it stopped recreational fishers wading in rivers – an activity which could disturb eggs attached to stones or gravel.

Marine tourism operators are threatening legal action against the Great Barrier Reef Marine Park Authority, or GBRMPA, over its decision to rubber-stamp a proposal allowing the dumping of dredging spoil inside the marine park.

Environment minister Greg Hunt had already given the North Queensland Bulk Ports Corporation approval to dredge the harbour at Abbot Point near Bowen, and that was signed off on yesterday by the GBRMPA.

The Great Barrier Reef

Colin McKenzie, president of the Association of Marine Park Tour Operators - the peak industry lobby group covering tourism in the reef region - has told Fairfax Radio that his group may take legal action to stop the dumping.

Mr McKenzie says it appears that the Authority members 'have lost their marbles'.

"The final authority had to be issued by the Authority. They had the ability to say no. The principal objective of the act is to provide long term protection and conservation of the environment, biodiversity and heritage value of the Great Barrier Reef region," he said.

"Now how the hell can the organisation responsible for ensuring that act is adhered to then allow anybody to go and dump millions of tonnes of rubbish on the Barrier Reef every year? That is just ridiculous."

The Great Barrier Reef Marine Park Authority says it has demanded a number of safeguards, including a limit on the amount of dredging spoil that can be dumped - but Mr McKenzie says the authority is pushing "a snowjob".

"Leadership of the Authority needs to be replaced. If they won't do their bloody job of preserving the environment out there then they should have people there that will.

"These guys are just pandering to the politicians. Politicians, if they want to change the act, should change the act. The GBRMPA should do what it is actually being paid to do - which is provide for the protection and conservation of the reef.

"When they talk about 1.3 million cubic metres (of dredging spoil), that's actually 2.3 million tonnes of rubbish that will be dumped on the reef.

"We have, over the last four years, been able to reduce the silt going out onto the reef by 360,000 tonnes. And we've spent $200 million doing it. Now we are going to let a mining company go out there and dump 2.3 million tonnes every year.

"We are talking about a massive amount of siltation - and then we have the mining industry, through the Queensland Resource Council, come back and say 'hey look, this is fantastic, we've stuck to the scientific facts'.

"Well, let me tell you, 220 scientists wrote to the GBRMPA saying 'do not grant this' because it will be bad for the reef. They [the Authority] are not looking at scientific fact, they are not looking at protection of the reef - they are just doing what their political masters want."

Mr McKenzie denies that tourism operators and environmentalists are opposed to any expansion of the coal terminal at Abbot Point, saying his member support the miners.

"We as an industry think that there IS a need to be able to export that coal. We absolutely support the mining industry in being able to get it out there.

"They could have done this with 'trellis' construction that would not have required any dredging but they didn't want to do that because it was a little bit more expensive.

"They'd rather dump their rubbish on us."

The tourism industry boss says the real concern to his members is one of uncertainty, not knowing how badly the dumping is going to affect the Barrier Reef.

"My guess is that it is going to reduce visibility in the Whitsundays even further, it is going to seriously stress all the corals in the region.

"The Whitsundays is south of the dumping point they are talking about, and the main current on the reef runs north to south.

"We are really, really concerned about this. The jewel in the crown of tourism is the Whitsunday islands and here they are saying 'let's trash it'."

Mr McKenzie has told Fairfax Radio that his group will continue to fight - and may take legal action if necessary.

"We will take it to [Environment minister Greg] Hunt, we will appeal this to the Administrative Appeals Tribunal, we will take it to court if we have to. I think the GBRMPA is in breach of their own act and that will be how we are trying to challenge this," he said.

A team of volunteers will be taking to the water by kayak near Canberra to tackle the scourge of Australian waterways - the willow.
The NSW Government is providing an additional $10,400 to a project called the Upper Murrumbidgee Demonstration Reach, which controls willow trees along 45 kilometres of the Upper Murrumbidgee.

NSW Minister for Primary Industries Katrina Hodgkinson and the member for Monaro, John Barilaro, on Friday announced a $10,400 grant for a fish habitat project to control willow trees along a stretch of the Upper Murrumbidgee River.

Ms Hodgkinson conceded it was not a huge amount of money but a ''wise investment'' in the health of the river.

''This is a terrific local project, which will improve the Upper Murrumbidgee River and provide better access for fish, improve fish habitats, and ultimately produce more fish,'' she said.

''Willow infestation is a major issue for river health and native fish habitats - it can destroy native plants and wildlife habitats, alter stream flows, cause flooding by blocking the natural watercourse, and reduce water quality.''

The money will be used to fund the Upper Murrumbidgee Demonstration Reach project, which extends from Bredbo in NSW to Casuarina Sands in the ACT.

The funding will cover about a 50-kilometre stretch from Bredbo to Angle Crossing at the NSW-ACT border.

Project facilitator Antia Brademann said they would work to control young emerging willows growing in-stream.

The aim is to remove the willows before they have a chance to establish, when they become more costly and difficult to remove.

''We're also interested in working with the landowners to work on the banks,'' she said.

Ms Brademann said willows could quickly colonise river banks and cause problems for the aquatic ecosystem. ''They block everything else and have quite a fibrous root mass, and that tends to affect habitats on the bank. Platypus also find it very difficult to burrow into the bank,'' she said.

''We also get leaf fall from the willow in the autumn and we often get a rotting muck at the bottom of the water. It degenerates water quality and raises phosphate levels.''

Senior aquatic ecologist with the ACT government Dr Lisa Evans said the territory would offer advice for the NSW side of the project. She said the ACT would also do cross-border fish monitoring to see if the project was having an effect.

The project is being led by the community organisation Kosciuszko 2 Coast, with other funding from the Murray Darling Basin Authority and Bush Heritage Australia.

Mr Barilaro said the project would result in a healthier, more resilient and sustainable river.

Abbot Point coal terminal in Queensland. Abbot Point in Bowen, Queensland is a gateway to the vast coal reserves of the Galilee Basin.

Abbot Point coal terminal in Queensland. Abbot Point in Bowen, Queensland is a gateway to the vast coal reserves of the Galilee Basin.

The Great Barrier Reef Marine Park Authority has approved a proposal to dump dredge spoil from the Abbot Point coal terminal expansion in the Marine Park area.

Three million cubic metres of spoil must be dredged as part of the project at Bowen in North Queensland green-lighted by Federal Environment Minister Greg Hunt last month.

Scientists and conservation lobbyists had urged the Authority to reject the expansion, with 233 signing a letter to chairman Russell Reichelt that said: "The best available science makes it very clear that expansion of the port at Abbot Point will have detrimental effects on the Great Barrier Reef. Sediment from dredging can smother corals and seagrasses and expose them to poisons and elevated nutrients."

Greenpeace warns that any dumping of dredge spoil on the World Heritage-listed reef will be an "international embarrassment" and akin to "dumping rubbish in the Grand Canyon".

"We wouldn't throw rubbish on World Heritage sites like the Grand Canyon or the Vatican City, so why would we dump on the reef?" spokeswoman Louise Matthiesson said.

"Scientists are clear that the potential impacts of dumping the dredge spoil so close to fringing reefs and the WWII Catalina plane wreck are significant."

The reef already faced pressures from climate change, land-based pollution and crown of thorns starfish outbreaks, she added.

What the expansion involves

The Abbot Point expansion will create one of the world's biggest coal ports, located about 25 kilometres north of Bowen on the central Queensland Coast and handling exports for companies mining the vast coal reserves of the Galilee Basin.

Various conglomerates, including Australia's own Gina Rinehart and Clive Palmer, are negotiating leases for the area.

According to the Great Barrier Reef Marine Park Authority, the area to be dredged is located about three kilometres offshore of Abbot Point and is "wholly contained within existing port limits of Abbot Point".

The dredging of "previously undisturbed seabed" is required to deepen an area around six new ship berths as part of the development of Terminal 0, Terminal 2 and Terminal 3.

While the area to be dredged is located within the Great Barrier Reef World Heritage Area, it is in an area excluded from the Marine Park.

Strict conditions, but are they enough?

Announcing the expansion in December, Mr Hunt said he was imposing strict environmental conditions on the project.

"It is my intention that the first priority for all future capital dredging projects within the central and north Queensland coastal zone will be for shoreline, near-to-shore or land reclamation disposal," he said.

"This follows my recent agreement with the Gladstone Ports Authority that they will not dispose of up to 12 million cubic metres of spoil within the marine park, but will instead use this material for land infill.

"This is a significant step towards improving and protecting the marine park for future generations."

Mr Hunt said one condition would be that any dredging would be limited to 1.3 million cubic metres of sediment a year and conducted during a "small window" nominated by environmental scientists.

He also said that he would demand "a 150 per cent net benefit requirement for water quality" in the reef area, a target that Wendy Tubman from the North Queensland Conservation Council said was unachievable.

"You've got water of a certain clarity, then you add three million cubic metres of dredge spoil, finds, sands, sludge," she said.

 

"Now I don't know about you, but I can't see how that's going to improve water quality."

Jon Brodie, a senior researcher at James Cook University, told ABC News Online that while the Federal Government had limited estimations of dredge spoil from the project to three million cubic metres, the effects would be "cumulative" and set a precedent for other developments along the Queensland coast.

Citing projects at major ports along the Great Barrier Reef coast - including in Cairns, Townsville, Hay Point (Mackay) and Gladstone - that could create as much as 80 million cubic metres of spoil, he said: "It will add to the destruction of a system that is already going downhill badly."

And over the next decade more dredging would be needed at Abbot Point to make room for future exports from Waratah Coal's Alpha North project, he added.

Is there an alternative to dumping spoil on the reef?

In announcing the expansion in December, Mr Hunt said the Government preferred that where possible, spoil from dredging be used as infill for land reclamation.

"There are great examples in Queensland where the material produced by dredging has been used for land reclamation - for example, the Port of Brisbane," he said in a statement.

Mr Brodie, who has outlined alternatives in an article published on The Conversation website, says that among "several options" for disposal of dredge spoil are building a retaining barrier, called a bund wall, like that used at Gladstone Harbor, adding that in the case of Abbot Point, "I really can't understand why that's not on the table".

However, unlike the wall at Gladstone, which the local ports authority has admitted leaked sediment into the harbour in 2011 and 2012, it would need to be "done properly".

"This would also have the benefit of increasing port land, an important consideration at Abbot Point as useable land is scarce," he wrote.

Another option was to build longer jetties, he added, reducing the need for dredging.

"The emphasis should be on designing ports in ways that safeguard the Great Barrier Reef, rather than causing damage and then trying to fix it," he wrote.

Among the 95 environmental conditions on the Abbot Point project, the Minister states a requirement for "identification of alternative disposal sites for analysis", although disposal at an alternative site will only be allowed "if it would have the equivalent or lesser impacts than the site".

Business groups, meantime, have applauded the Government's decision to allow the expansion of the port.

Bowen Chamber of Commerce chairman Bruce Heddich said: "Bowen, being adjacent to Abbot Point, is the real winner in this decision. It can only go well for the future of the town."

And Queensland Resources Council chief executive Michael Roche praised Mr Hunt for using the weight of scientific evidence to put Queenslanders ahead of "increasingly hysterical environmental activists".

"The trading ports working alongside the Great Barrier Reef are responsible for the export of commodities worth $40 billion a year to the Australian economy," he said.

The ConversationOriginal story by Barbara Norman, University of Canberra at The Conversation

The Great Barrier Reef Marine Park Authority has announced it will allow the dumping of three million cubic metres of dredge spoil from the Abbot Point port redevelopment within the marine park’s boundaries, despite other options being available to them.

In doing so, the authority ignored the pleas of a wide coalition of interests that went well beyond the environment movement. The Queensland Tourism Industry Council, the Association of Marine Park Tourism Operators, Whitsunday Charter Boat Industry Association and Dive Queensland had all expressed “grave concerns” about the effects of the dredge-dumping plan on their industry.

So why are so many people concerned? In part, because Australia is now a step closer to seeing the reef being added to a list of World Heritage sites “in danger”, possibly as soon as June this year.

While some may dismiss that “in danger” listing as symbolic, it could affect reef tourism, which Deloitte Access Economics has estimated brings in A$6.4 billion a year to Australia in direct spending and employs more than 64,000 people.

So what happens next? And is there anything Australia can do to avoid being added to that “in danger” list?

Protecting our reputation

The federal government is due to report by tomorrow to the World Heritage Centre about what Australia is doing in response to global concerns about the impacts of climate change and rapid coastal development pressures on the reef.

In June, the World Heritage Committee will then consider whether to add the Great Barrier Reef to its list of iconic global sites officially considered to be “in danger”.

The committee’s principal concerns include the “cumulative” impacts and risks to the reef - that is, the combined effects of several individual developments, including continuing coastal urban development and large-scale port expansions such as the Abbot Point project.

It has asked the Australian government for commitments to “ensure that the legislation protecting the property remains strong and adequate to maintain and enhance its ‘outstanding universal values’”.

Between now and June, if the Australian government can answer the committee’s concerns then there is still a chance that the reef will stay off the “in danger” list - or at least have that decision be deferred. However, the Abbot Point dredge dump decision has undoubtedly made the task much harder.

Meanwhile, the committee has also asked Australia to prepare a long-term sustainability plan, which is due to be completed by February 2015.

As a signatory to the World Heritage Convention, Australia has pledged to implement world’s best practice in protecting the reef for future generations.

International concern

The World Heritage Committee has previously raised concerns about the state of the reef, particularly concerning the dredge-dumping proposals. In its review of the health of the reef it recommended:

A clear and target-driven framework to support planning and assessment of development proposals to protect outstanding universal value, and restore it where necessary, and to ensure resilience of the site, including the consideration of cumulative impacts.

In spite of that international concern, the federal government has made several decisions within the past two months that arguably erode safeguards for the reef, including:

  • 10 December 2013 – granting approval for the Abbot Point port expansion (although it was the Great Barrier Reef Marine Park Authority that took the decision on where to dump the spoil).
  • 13 December 2013 – reaching a revised agreement with the Queensland government (signed by Prime Minister Tony Abbott and Premier Campbell Newman) for a “one-stop shop” on environmental approvals, including decisions about “actions on state land and state waters that impact on the Great Barrier Reef Marine Park”.
  • 20 December 2013 - approving the Galilee Coal and Rail Project, allowing for six new mines and a railway from the mine sites (400km inland) to Abbot Point.

Those are all significant decisions to be making, which will have long-term ramifications for the health and tourism value of the reef.

Seeing the bigger picture

On a more positive note, federal environment minister Greg Hunt has promised that the Australian government will be “examining the cumulative effect of human activities and natural forces rather than looking at impacts in isolation”.

Late last year, the Great Barrier Reef Marine Park Authority also expressed concern over “cumulative impacts of coastal development activities on ecosystem function”. The key question is how will this be achieved given the development decisions that have already been taken.

In November last year, former deputy prime minister and Nationals leader Tim Fischer told a Queensland planning conference that more lateral thinking was needed on ports and coastal development. Mr Fischer suggested that instead of five individual ports along the Queensland coast, each with their own railway line, another option could be one “super port” away from the Great Barrier Reef.

It’s a great idea - but it’s the kind of big-picture thinking that has been sadly lacking in planning for the reef and coastal Queensland to date.

What is really needed to rescue the reef is an integrated regional plan. That would take into account the environmental impacts both on land and on water, from port development and associated infrastructure, coastal urban development, agriculture and tourism. It should also factor in impacts such as farm run-off and climate change.

Without such a plan, decisions such as those taken about Abbot Point are piecemeal and premature.

As a maturing developed nation, it’s time for Australia to decide what is really important to our future. Protecting the Great Barrier Reef – one of the great wonders of the world and a treasure to be preserved for future generations – must be on that list.

Media release at the University of British Columbia

The key to clean water and sustainable fisheries is to follow nine guiding principles of water management, says a team of Canadian biologists.

Fish habitats need ecosystems that are rich in food with places to hide from predators and lay eggs, according to the framework published today in the journal Environmental Reviews.

Humans have put key freshwater ecosystems at risk because of land development and the loss of the vegetation along rivers and streams, says John Richardson, a professor in the Dept. of Forest and Conservation Sciences at the University of British Columbia, one of 15 freshwater biologists who created the framework to help protect fish and ecosystems into the future.

“Fish are strongly impacted when nutrients, sediments or pollutants are added to their habitat. We cannot protect fish without maintaining a healthy freshwater ecosystem,” says Richardson, who led the policy section on protecting fish habitats. Other policy sections addressed areas such as climate change and biodiversity.

Connecting waterways are also critical for healthy ecosystems, says Richardson. “If fish can’t get to breeding or rearing areas because of dams, culverts, water intakes or other changes to their habitats, then the population will not survive,” he says.

With more pressure on Canada’s freshwater ecosystems, Richardson and his colleagues wanted to create a framework of evidence-based principles that managers, policy makers and others could easily use in their work. “It’s a made in Canada solution, but the principles could be applied anywhere in the world,” he says.

BACKGROUNDER

Healthy freshwater ecosystems are shrinking and reports suggest that the animals that depend on them are becoming endangered or extinct at higher rates than marine or terrestrial species, says Richardson. Humans also depend on these ecosystems for basic resources like clean drinking water and food as well as economic activity from the natural resource sector, tourism and more.

The components of a successful management plan include:

  • Protect and restore habitats for fisheries
  • Protect biodiversity as it enhances resilience and productivity
  • Identify threats to ecosystem productivity
  • Identify all contributions made by aquatic ecosystems
  • Implement ecosystem based-management of natural resources while acknowledging the impact of humans
  • Adopt a precautionary approach to management as we face uncertainty
  • Embrace adaptive management – environments continue to change so research needs to be ongoing for scientific evidence-based decision making
  • Define metrics that will indicate whether management plans are successful or failing
  • Engage and consult with stakeholders
  • Ensure that decision-makers have the capacity, legislation and authority to implement policies and management plans.

These recommendations are based on nine principles of ecology:

  • Acknowledge the physical and chemical limits of an ecosystem
  • Population dynamics are at work and there needs to be a minimum number of fish for the population to survive
  • Habitat quantity and quality are needed for fish productivity
  • Connecting habitats is essential for movement of fish and their resources
  • The success of freshwater species is influenced by the watershed
  • Biodiversity enhances ecosystem resilience and productivity
  • Global climate change affects local populations of fish
  • Human impacts to the habitat affect future generations of fish
  • Evolution is important to species survival
