Powerboat racing on the Derwent River

I discovered the northern end of the Murphys Flat wetlands area came abruptly to a stop at the competition grounds for the Motor Yacht Club of Tasmania’s (MYCT) powerboat racing events (more information further below).

The area has a bland, functional entrance and I guess all the action and beauty happens on the Derwent River.

The site is shared with another aspect of local community history.

A metal arch over nothing and through which you don’t seem to be directed to walk, features the words HC MILLINGTON MEMORIAL AQUATIC with the letters MYCT over the top of the arch.  Millington’s Funeral Directors are well known in Hobart and it seems that the archway refers to Mr Harold Charles Millington who started out as a sometime professional cyclist and a wood craftsman before entering the funeral industry when, during the 1930s depression, people couldn’t afford new furniture but they died and were in need of burial coffins.  He died in 1969 so I am guessing the archway was built in the 1960s. I found Australian Powerboat Racing Association records for 2012 indicating the HC Millington perpetual trophy was no longer in use or destroyed. Was the dramatic archway and the trophy philanthropy, pure sponsorship or the result of lots of business arising from the area?  Why such an arch in an area where there are no houses and people would seldom visit?  Does anyone know the answer?

The area has been well cleared for vehicles and their boat trailers to be parked. This provided a dramatic contrast after the density of vegetation along Murphys Flat.

Even though the MYCT is based in Lindisfarne (I passed its club house during an  earlier walking stage), it runs powerboat racing competitions in conjunction with the Tasmanian Council of the Australian Power Boats Association, around Tasmania including at this Derwent River side facility between Granton and New Norfolk. Interested? Want to know more? Go to http://tasapba.com/about_us.html and at least one or two photos look like they were taken on the Derwent River.

As I researched information about the site, seeking the quirky and unexpected, I found that a Dianas on the Derwent race meeting is scheduled annually. No idea what that really means but I have taken a fancy to the title. In Roman mythology Diana was a virgin goddess of the hunt, the moon and childbirth with the power to talk with and control wild animals.  Perhaps the Dianas on the Derwent is a very young women’s racing event, where they hunt a winner’s trophy by racing at night, and their boats are their wild animals that require taming.  But childbirth?  Where does that fit?  Then I discovered a couple of You Tube videos and a related Facebook page. For example, https://www.youtube.com/watch?v=bs15dNuhMcw. In the video note the hands look male – so my theory about living goddesses driving speedboats seems to have flown. So what is this Diana thing about? Anyone know?

A 10 am I was back walking on the Lyell Highway having discovered that access to the road northwards along the Derwent River shoreline was impossible with barbed wires fences blocking the way.

Green Island – do you know it?

How many islands are green with vegetation? How many blots of land are named Green Island? Probably many thousand.  Tasmania has a few ‘green’ geographical features spread around the state – followers may recall in an earlier walking stage I rounded Green Point on the eastern shore of the River. My walk along the Derwent River last week passed by a green Green Island.

While walking the length of Murphys Flat toward the northern end, across the water of the Derwent River I caught glimpses of a small length of low lying land in the flow of the Derwent River. Green Island was almost invisible from the western shore because the grasses in the Murphy’s Flat wetlands have grown tall.

This small piece of land provides a safe haven in which fish hang about the edges. New Norfolk Anglers Club members and others have enjoyed catching tagged salmon here.

Green Island is looked over by Mount Faulkner on the south western side of the river, and by Mt Terra and Mt Dromedary on the north eastern side.  On the map below, my arrow points to the slim Green Island near one bank of the Derwent River. The Lyell Highway is the yellow line curving through the lower part of the landscape. Murphys Flat is the fat area between the Highway and the River.

Why are these wetlands called Murphy’s Flats? Who was Murphy?

Thanks to http://www.parks.tas.gov.au/file.aspx?id=17347  I know that “Murphys Flat Conservation Area historically formed a portion of the property locally referred to as Marsh Farm, which was established through an ambitious land reclamation endeavour begun by Governor Arthur in 1824. The property was hailed as an agricultural “show place” throughout Tasmania and was one of the earliest land reclamations in Australia.”

The site http://www.derwentestuary.org.au/assets/NIE_-_wetlands.pdf provides the information that “In 1997 we nearly lost 40% of these wetlands when a farmer started draining the 66 hectare marsh known as Murphy’s Flat.”  This action was the catalyst for various tiers of government to step in and fund the process to purchase the land and retain it as a conservation area. The area known locally as Murphys Flat was acquired on 1 May 2001 by the Tasmanian Parks and Wildlife Service.

The 2010 Management Statement at (http://www.parks.tas.gov.au/file.aspx?id=17347) is informative.

Murphys Flat Conservation Area is located within a wetland complex on the southern shore of the River Derwent beside the Lyell Highway between Granton and New Norfolk. The area has been recognised as being particularly species rich, with expansive areas of marshes, underwater grasses, tidal flats and reed beds that provide habitat and breeding areas for large populations of fish, platypus and waterfowl. Murphys Flat Conservation Area comprises 25 to 30 per cent of remaining wetlands in the River Derwent. It is listed within both the Directory of Wetlands of National Significance and the Tasmanian Geoconservation Database.

Birds are particularly abundant in the reserve due largely to the diverse habitat. The vicinity is well known for its large population of black swans and it is a likely hunting and foraging area for five significant bird species including the wedge-tailed eagle, white-bellied sea-eagle, swift parrot, masked owl and great crested grebe. The secretive, little-known Australasian bittern is also known to occur there.

Murphys Flat Conservation Area serves as a nursery for the sandy flathead and also provides important shelter for other juvenile native fish. Backwater areas of the reserve are of particular biological significance with unique botanical assemblages and an abundance of gastropod molluscs.

Until the early years of this century, “Murphys Flat was used as a dump site for domestic rubbish, garden waste and for overburden from road and earthworks. As a result, the area of wetland vegetation communities has decreased and its condition has been further compromised through the spread of weeds, largely from this source.” Now a weed control program has been instituted. “The vision for Murphys Flat Conservation Area is that it will contribute significantly to regional biodiversity and geodiversity in the upper River Derwent estuary, provide water quality services and research opportunities and be a vehicle for increasing public awareness of wetland values.”

In addition to the natural history and situation, Murphy’s Flat has a cultural history.

Firstly, the site is reported to have been on a travelling route for two Aboriginal tribes (http://www.parks.tas.gov.au/file.aspx?id=17347).

Then, according to Kelvin Markham at http://www.km.com.au/tasmania/ch14.htmFour miles beyond Granton stood a derelict grey stone house, known to all and sundry as The Haunted House. No one can tell why it received its name, though it is popularly (and wrongly) supposed to have been the country seat of early governors. The haunted house was originally the Golden Fleece Inn, licensed on 22 October 1824 to one Henry Fitzgerald. It did not long cater for travellers and in 1837 was on the market. This building was also called Addington Lodge Villa at one time.”

The National Library of Australia (http://trove.nla.gov.au/ndp/del/article/30094484?searchTerm=Anthony+Geiss) offers the information that “Addington Lodge was named after Mr. J.H. Addington, the Secretary to the British Treasury at the time. It was constructed by Governor Sorell to serve as a country house in 1820, a year after the construction of the Hobart to New Norfolk Road. The lodge was a double storey brick house with an architectural style typical of a late Georgian villa with symmetrical doors and windows and a wide fan-lit front door. The lodge was renamed the Golden Fleece Inn and opened to the public after a Mr Barker sold it to Mr. Henry Thomas Fitzgerald in 1824 having owned it for 4 years only. Addington Lodge at Murphys Flat became a popular half-way house for travellers between Hobart and New Norfolk and earned an unsavoury reputation.”

If remains of this house still exist they are now obscured from view by the lush vegetation  growing across the wetlands.  I saw no sign of it as I walked past Murphy’s Flat.

To give you some idea about the look of the wetlands from the Highway, the photo below shows the landscape when I looked back over the road just walked.

Along the kilometres (Murphys Flat Conservation Area is approximately 2.7 kilometres long and 550 metres wide at its maximum width) of Murphy’s Flat Wetlands, the vista consisted of subtle variations of the following:

When I walked, most of the landscape between the Lyell Highway and the smoothly flowing Derwent River seemed impenetrable. I can only imagine this is a very safe place for water birds and fishlings to breed, and for native grasses and other plants to re-establish.

This posting started with a question which I have been unable to answer. I cannot discover who Murphy was. Regrettably.

Murphy’s law is a commonly heard saying which is typically stated as: Anything that can go wrong, will go wrong.  I wondered if the land now known as Murphy’s Flat had been purchased for the purpose of grazing animals and growing crops without due checking, and then found the wet soggy land to be useless in the days when preservation of native flora and fauna was not considered – I wondered if someone bought the land without really checking how it was and having spent all their money decided Anything that can go wrong, will go wrong. BUT according to the definitive book The History of Murphy’s Law written by Nick Spark, this adage was named after an American aerospace engineer Captain Edward Murphy who said as much around 1950. The naming of Murphy’s Flat at Granton seems to have preceded this ‘law’ so the area must have been named after a local – but who was it?  More research required.

Google maps cannot locate Murphy’s Flat so I have attempted to indicate the location this posting has referred to.  Within the hand drawn oval above, the Murphys Flat Conservation Area sits contained between the Derwent River and the Lyell Highway.

Fish dying in the Derwent River

In early March Tasmania’s Inland Fisheries Service received a report of dead fish in the Derwent River between upstream New Norfolk and the area downstream near the industrial mill Norska Skog. For further reading refer to http://www.ifs.tas.gov.au/news/river-derwent-fish-kill-restricted-to-barracouta.  The thinking was that “The most likely cause is that barracouta have followed the salt wedge with the high tide in the river and killed by their sudden entrapment in freshwater.”

One of this week’s news stories reported on monitoring the unexpected numbers of fish dying in groups. The story can be read at http://www.abc.net.au/news/2015-03-27/more-monitors-on-river-derwent-as-fish-kills-continue/6354950. In an earlier article http://www.themercury.com.au/news/tasmania/experts-examine-mass-fish-kill-in-upper-derwent-estuary/story-fnj4f7k1-1227256722478, the thinking was that “Water quality in the lower saline layer is typically poor in summer.

Quite separately another story was running and I can find no-one publically connecting the two: “Fish kills could occur if the large algal bloom in the River Derwent near the Murphys Flat wetlands grows.”  For further information read http://themercury-au.newspaperdirect.com/epaper/viewer.aspx.

I expect to be walking past Murphy’s Flat in the next day or so and I hope not to smell dying fish or see the silvery scales of dead fish littering the River’s edges.
