Australia's lost urban waterways – sites for the daylighting urban streams map?

Tank Stream, Sydney

Sydney’s Tank Stream is significant in Australia’s colonial history, but is now buried in stormwater drains. It is one of many lost waterways around the world that have been buried beneath our urban

areas. There are substantial economic, social and environmental benefits of daylighting these lost urban streams.

A new website developed by the University of Sheffield (UK) has been developed for practitioners, water managers, policy makers and anyone with an interest in river restoration and sustainable urban design. It is a resource of case studies from all over the world, collating information on the goals and outcomes of daylighting projects. This is helping to share knowledge and expertise across the world, connecting like-minded individuals, and demonstrating the benefits and challenges of daylighting urban streams.

Everyone is invited to browse the case study map and add new sites – even if they are only in the planning stage – and connect on Facebook.

In Search of the Trout Cod

Siwan and I are very fortunate to be working with the Native Fish Strategy at the Murray Darling Basin Authority on a project involving Will Trueman (researcher and author) and Richard Snashall (film maker).

Will has undertaken an incredible piece of research, over many many years, into the status of native fish in the lower Murray Darling. Will has successfully combined the science, the historical records (newspapers, books and photographs) and anecdotes (oral histories) from sometimes very elderly residents of the region, to show just how prevalent the Trout Cod, Murray Cod, Macquarie Perch and many other native fish were in the 1860s up to the present day.

Will has done an exceptional job of combining science and story to create an accurate record of the status of native fish in the basin over the last 150+ years. He has also drawn on the writings of Mary Gilmore which are absolutely fascinating (more on this in later blogs) and now I find I am also reading all these wonderful accounts of early Australia. Using this variety of information he has created a captivating history of the loss of native fish from the region and what may have caused some of these losses.

The products of this project will include the full publication which will be submitted to the legal deposit libraries across Australia as a research record; a series of catchment by catchment publications, a web site with links to all the information; and several videos of Will sharing the stories and science that make up this amazing project. I was particularly impressed to hear that Will used Trove at the National Library of Australia to access the old newspaper records.  He told us that this research made up 30% of his primary source material and he could not have undertaken the level of research without having access to Trove.

I am particularly taken with this newspaper article about the size and aggression of the Trout Cod which Will found in the Trove database.

Murray Fish and their Habits (From our own correspondent) Blanchetown, May 15.

The Murray cod may be caught from one – quarter of an inch in length to over 100 lb. in weight. / A young German, an assistant at a wool washing establishment about five miles from here, was in a habit of bathing off the stage, and one day while having his usual dip sat on the stage with his feet swaying to and fro in the water, when a cod seized his foot, at the same time nearly forcing him off the stage into the water, the German having his foot severely scarred by the teeth of the cod. Some time elapsed before he recovered. At Weston’s Flat, a short distance above Morgan, the residents were in the habit of swimming their stock across the river for feed, and while swimming one of the horses it turned on one side, and with difficulty the boatman towed it to the shore, and with aid of blocks and tackle hauled him onto dry land, when, to their surprise, a huge cod had the horse’s foot in his mouth. The cod was captured, and weighed over 90 lb. Without doubt in some of the numerous cases of drowning, where good swimmers have disappeared, they have had a tussle with one of these “monsters of the deep.” 

This is just one sample of the newspaper articles collected by Will in his research.  The anecdotes collected from the fishermen are even more fascinating, but you will have to wait for the publication (expected by the end of 2011) for more.

Hawkesbury Nepean River Recovery Program (HNRRP) e-news June 2011

The last edition of HNRRP e-news discussed how the Hawkesbury-Nepean River Recovery Program is meeting one of its key objectives – the prevention of an estimated 48.2 tonnes of nutrients (nitrogen and phosphorus) entering the Hawkesbury-Nepean river system each year. In the June 2011 edition of HNRRP e-news we look at our other key objective – securing 7.24 gigalitres (billion litres) per year for additional environmental flows in the Hawkesbury-Nepean river system. You can also read about the HNRRP projects and how they are progressing as the program nears completion.

Australian Stream Management Conference – ‘Managing for Extremes’ Feb 6-8 2012!

We are so pleased that the Australian Stream Management Conference is making a comeback in 2012 – there has been a big gap in the calendars of natural resources management professionals without this event, so we are very happy to announce that the ARRC is going to be a part of this revamped occasion in February 2012.

The conference will be held in our home town of Canberra, with the River Basin Management Society and  the Catchments Australia Foundation hosting the event.  The ARRC will be running workshops that link to the conference theme of ‘Managing for Extremes’ with some of the questions being asked over the two days including:

Does successful management of stream systems lie in managing for the extremes?
What are these extremes, and how do we predict and plan for them?
What are the implications for ecological communities and monitoring and evaluation programs?
How do we engage with communities and elected leaders to discuss these issues?

The ARRC will be exploring  this topic in terms of what skills do we, as natural resources management professionals, need to ‘manage for extremes’.  How can we best support and facilitate positive environmental and social outcomes in the face of these future challenges?

Place the dates 6-8th of Feb 2012 in your diary and we look forward to welcoming you to lovely Canberra!

Hawkesbury Nepean River Recovery Program (HNRRP) e-news March 2011

The Hawkesbury Nepean River Recovery Program (HNRRP) aims to help improve the health of the river system by reducing the amount of nutrients entering the river system and making more water available for environmental flows. The March 2011 issue of HNRRP e-news explores one of these important objectives, looking at how the HNRRP is working to prevent an estimated 48.2 tonnes of nutrients entering the river system each year and discussing how this will benefit the river. You can also read about the start of works for the Hawkesbury City Council South Windsor Effluent Reuse Scheme and some interesting insights into other HNRRP projects.
