WATERSHED MOMENTS. EXCURSION 4. FOREBODING.

11 July 2021

I am back at the magnificent Stanmore Sewer Vent. It is going to rain, but I have started out on this episode of my walk around the rim of the Johnstons Creek catchment because I want to photograph the vent under an overcast sky. Last time I was here the dappled shade from street trees obscured the details of its flaking sandstone plaque which, it turns out, reads METROPOLITAN BOARD OF WATER SUPPLY & SEWERAGE 1900.

As I stand back to get a full-height shot of the vent and its accompanying house, a man runs across the road, angrily kicking a piece of wood as he goes, and enters the cottage’s front gate. I call out, ‘I hope you don’t mind’ and he growls, ‘You can take photos of a sewer vent any time’.

Our route takes us round into Percival Road, the main street of Stanmore, flanked by more neat turn-of-the-20th-century houses and leading down to a park, the railway station and a small cluster of shops. The sky to the south is looking ominous.

The rim line runs between houses and emerges in the lane behind, where I find a garage roller-door tribute to the composer Philip Glass complete with sketch portrait.

In an adjacent lane a man is taking his kids and dog for their permitted outdoor exercise in their local government area.  Apart from the cranky sewer vent resident we have, as usual, seen practically no-one on our walk. People are all inside as the Covid situation worsens. In the state of New South Wales there have been 77 new cases today and one death.

(The previous paragraph now seems ridiculous. I need to point out here that, although I took this walk on 11 July 2021, I have not got round to transcribing my notes until six months later. The Covid comparison is staggering.

I am composing this blog post on 1 January 2022, when 22,577 new infections have been recorded in New South Wales and four deaths. The reasons for the differing case number statistics (but reasonably similar death rate) between July and January include the intervening advent of the Delta and Omicron variants of the virus, the lifting of lockdowns and restrictions on movement, and a very high proportion of the adult population fully vaccinated.)

It is spitting now and we have not brought umbrellas, so we loop back around to the car, passing a cute domestic wall decoration on the way. Safely ensconced at home I think I might listen to some favourite music – Philip Glass perhaps.

WATERSHED MOMENTS. EXCURSION 3. REVELATIONS.

4 July 2021

When I began my circumambulation of the Johnstons Creek catchment rim I was prepared for the unexceptional. Unlike last year’s explorations of the creek itself – when I found offbeat backstreets and mini banana jungles – on this series of excursions I expected that only the occasional quirky garden ornament or letterbox would relieve the familiarity of the suburbs I passed through.

This image has an empty alt attribute; its file name is 20210704_123310_BlogMilkmai.jpg

To some extent this is turning out to be the case, but on this third excursion I have a moment of revelation, and I also come across very large infrastructure treasure that somehow I had overlooked in all the years I have lived in the inner west of Sydney.

I started where the imaginary catchment line emerges from between two small, pretty and unremarkable brick houses in a style common to this neighbourhood of Stanmore. Nothing much is going on in the street except for an elderly woman taking in some sun on this cold but bright day.

I stand in the middle of the road and look southeast down the slope. From here I can see across to the other side of Stanmore, and beyond that what must be the telecom tower on the opposite ridge in King Street, Newtown. I am surprised to realise I am looking across the valley of Johnstons Creek. This may seem obvious – I am, after all, standing on the catchment rim – but momentarily I understand the topography of the area without the distractions of urbanisation. There is no way I can properly capture what I am seeing in a mobile phone photograph.

I do not walk down the slope, but keep following the ridge as best I can as it winds between houses, across streets, down back lanes. I am getting closer to the less respectable surrounds of Parramatta Road; graffiti and garage-door murals are starting to appear.

Then, beyond the Seventh Day Adventist Church, I spot another surprise. It is the top of a tall, brick sewer vent.                                                  

My route takes me through more twists and turns until I come to the entrance of Percival Lane. And there, on the next corner, is the magnificent sewer vent standing in the front yard of a little house. White wisps of condensation float from the chimney into the cold blue sky.

Just half an hour ago I had a flash of insight into this area’s geomorphology. But now I have reverted to admiring the monumental accoutrements of civilisation.  Later I will read that this is a ‘classicist late Victorian sewer vent’ with Sydney Water heritage number 4572732.

I have had enough excitement for the day and resolve to resume my walk on an overcast day when I can get photos of the vent and its house without the dappled shadows cast by street trees. I return to the car via a lane beside the Seventh Day Adventist Church, where earlier I noticed a rustic little table in a throwout pile. I will use it as a plant stand in my backyard.

Watershed moments. Excursion 2. Tin bird territory.

There’s a man up a ladder picking inedible figs as his dog watches on. Eye-catching in its simplicity, this back-lane mural will turn out to be today’s most interesting find as I resume my tracing of the Johnstons Creek catchment rim.

I am in the staid north-western corner of Stanmore, which is characterised by rows of neat, late 19th century houses. Yaz, the Completing Sydney blogger, visiting this suburb for the first time not so long ago, decided that ‘here is that combination of historic and adorable that we come to expect from the Inner West’, making it ‘the kind of place you might want to live in if you’re after that quiet suburban life, not too far from the city – perfect for small families who also happen to be multi-millionaires’.

As I emerge from a knot of neat, rubbish-less back lanes there is an imposing house opposite with bird cowls on its chimney. Spot the real bird on the television aerial! I’ve had to look up ‘bird cowl’, the correct term for these covers that apparently increase the draft of a chimney. In this neighbourhood there are flocks of them. Perhaps the original builders of these houses did not foresee that ridge-top winds would blow smoke back down the chimneys. Original features, such as mantelpieces and fireplaces, are a real estate selling point in Sydney’s older suburbs, but I wonder how many owners persist with wood fires for their heating in winter?

After turning a few street corners I come to a place where the ridge line ducks between two houses. Detouring round the block to get to the spot where the line emerges in a rear lane, I will use the tall palm tree as a marker.

I find the palm tree, but I have been out for the allotted Covid-safe outdoor exercise hour so it’s time to head back to the car.

In any case the clouds are louring and it’s going to rain again. I turn my back on another flock of bird cowls bracing themselves for the worst.

Watershed Moments. Excursion 1. The water tower.

Another lockdown. A new walking project. I’m still fixated on Johnstons Creek, but this time I’m following the rim of its catchment area, a route that will take me along the ridges of Petersham, Stanmore and Annandale. And that is as far as I will get while restricted to my local government area.

I begin at the highest point west of the Sydney CBD before the Blue Mountains. You might call it Sydney’s upper inner west. It’s right where the landmark Petersham Water Tower is poised – this heritage-listed, concrete engineering marvel. This afternoon a group of currawongs is enjoying the rim of the tower and its updrafts.

Using Sydney Water’s stormwater catchment map, detailed down to individual blocks of land and house numbers, I head north along Crystal Street, stopping to turn around and photograph a relic of traffic signs past. It’s a ‘SLOW’ warning written in metal studs on the concrete. I manage to photograph it (not for the first time) during a traffic light-induced gap between vehicles.

Where Crystal Street crosses the railway line I am still on high ground. From the bridge you are supposed to be able to tell if it is snowing in Oberon, on the other side of the Blue Mountains. My friend who lives there says I should look for a green cloud. Today there is no faraway green cloud but I do catch late afternoon shafts of light.

The perimeter of the Johnstons Creek catchment area, as it is indicated on the Sydney Water map, is sometimes curved in places where old roads have followed natural ridges. But more often it becomes a series of straight lines at angles to each other, where streets have been laid out in a grid that disregards topography. In those places the map outline fudges the lie of the land in order to conform to the alignment of streets, lanes, buildings or water pipes.

I turn east off Crystal Street but come to a point where the map line darts between two houses. Since I can’t walk through people’s property (nor am I physically able to climb over back fences) I must backtrack and walk all the way round to meet the imaginary line in the next street parallel. I can see that this is going to happen over and over again on my series of excursions.

The last part of today’s trip takes me through some disappointing back lanes. In this neat part of Petersham there are wheelie bins in the lanes but no piles of discarded junk for me to cast my eye over, only the occasional mystery abandonment. It is starting to rain and I turn back.

Concrete Creeks. Excursion 11. The valley.

Monday 22 June 2020

For this last journey along Johnstons Creek we take a path not far from Tramsheds, but on the opposite side of the canal. To follow the concrete line of the canal towards Rozelle Bay, we begin beside a skate ramp and an assembly of earth movers standing by to work on Sydney Water’s ‘naturalisation’ project.

Not far along the sandy path I am surprised to see a reed-fringed pond with a signboard, ‘Federal Park Wetland’. The sky to the north is threatening, but above us there are blue patches and their reflections match the colour of the pet supplies barn beyond the trees. Overflow from the pond empties into two basins and, on the other side of the path, we see that it has run underneath us to the canal.

The tide is out, or perhaps it was prevented from coming in. The canal is dishevelled, strewn with pipes, barricades and building site paraphernalia. Water pumped from somewhere upstream pours from a large black hose. This scene is so different from the almost-idyllic autumnal waterway that we looked back on from the sunny Glebe foreshore in April.

The rail viaduct is the next landmark. Built to carry steam trains taking goods to and from Darling Harbour, it has since been modified with overhead electric wires for the Metro light rail. From where Federal Park has widened out into a grassy but soggy playing field we can look back and admire its elegant curve and graceful brick arches.

Further on, after stepping along a temporary plastic path between safety fences, we arrive at the feted and recreated Allan Truss Bridge. This is the spot where we abandoned our foreshore outing in April, which means we have completed our piecemeal exploration of Johnstons Creek proper, from drain to bay. Over the weeks we have encountered twelve bridges across the canal, passed under two mighty viaducts, and walked over countless hidden feeder pipes and drains.

The characteristic salty-muddy smell of a tidal flat accompanies us as we cross the truss bridge. On the other side a large section of Bicentennial Park has also become a reconstruction site, where hard hats must be worn and 1.5 metre distancing observed.

We now return to where we started today, this time taking a route along the eastern side of the canal between more wire safety fences and the trim white picket fence of Jubilee Oval.

Back at the two bridges that cross from The Crescent in Annandale to Harold Park and the Tramsheds food mall in Forest Lodge, I look upstream towards the vast residential development that has replaced the Harold Park Paceway. Before embarking on this last Johnstons Creek excursion I have done some reading and I now realise that this whole area is a broad, flat valley. Although there are acres of open space, nothing is orginal. Not the concrete-confined creek, nor the planted reed beds and grassy slopes in front of me. Behind me, not the little wetland, the tidy playing fields and parks, the Indian mynahs splashing in the canal, nor the neatly walled edges of Rozelle Bay.  Not even the trees.

In this valley Johnstons Creek once stretched out as a wide estuarine wetland with tidal mudflats and mangrove thickets, but in the 19th century the valley was filled with spoil from elsewhere in the curiously misnamed process of reclamation.

Over the generations since then, various organisations and departments have argued and compromised and acted to shape the land to their various needs and wants – grassy parklands and avenues of trees, factory sites, warehouses, timberyards, tramyards and a racecourse. Similar wrangling has characterised more recent efforts to restore fragments of the ‘reclaimed’ valley to a semblance of its former self.

So we have reed beds adjacent to a high-rise development, an artificial wetland fed by real runoff, newly planted patches of native vegetation (some already infiltrated by exotic weeds), and a corner of  mangroves in an area small enough that it doesn’t encroach on open space. The latest change is Sydney Water’s grand naturalisation project which includes, among other things, replacing the concrete banks of the canal with sandstone and native plants, and expanding the salt marsh around it. The City of Sydney’s concurrent scheme to improve The Crescent and Federal Park will feature less natural works, like a skate plaza and picnic areas with barbecues. 

During my walking and reading explorations I have been disappointed not to find specific references to pre-20th century Aboriginal people who might have frequented the immediate environs of Johnstons Creek. Recently written descriptions and histories of the surrounding suburbs usually begin with the obligatory generalised nod to the Cadigal and Wangal people of this area before getting on with the ‘real’ history. But even in serious accounts I have found no mentions of these people that can be pinned specifically to Johnstons Creek, nor can I find any stories handed down through generations, or contemporaneous mentions of Aboriginal people being seen here, or any records of archaeological discoveries.

It stands to reason. The region now covered by the suburbs of Stanmore, Camperdown, Annandale and Forest Lodge was very close to the original colonial settlement of Sydney, so even before the very early land grants were made here, most Aboriginal people had probably gone. During the subsequent periods of farming, subdivision and urbanisation, any traces of the original people would have been dug up, buried, built over or wilfully ignored.

Still, there is enough evidence from nearby or similar areas to suggest how these people lived. They might have hunted in what the colonists called the ‘Kangaroo Ground’ where Johnstons Creek rose. The might have accessed its fresh water. They would have probably frequented the sandstone ridges of now-suburban Glebe overlooking the estuarine valley, staying in overhangs like the rock shelters with associated middens that have been found not so far away in Lilyfield and Birchgrove.  

They would not have lived in the watery valley but almost certainly foraged there, just as people did in the long-ago ‘reclaimed’ Blackwattle Bay on the other side of Glebe Point, where archaeologists have recently uncovered several deposits of stone artefacts. Glebe historian Max Solling says there is ‘some evidence of Aboriginal middens – the remains of shellfish – in the narrow strip of remnant salt marsh fringing the lower parts of Johnstons Creek. The ark cockle, scallop and Sydney rock oyster and mud whelk found there indicate that this was a fertile swamp and a rich source of food for the first inhabitants’.

As this stage of my Covid-19 isolation project comes to an end social restrictions in New South Wales have been eased. I am not sure that I could muster the number of friends I am allowed to mingle with, but later in the week we are having lunch with two friends. They are volunteers with the State Emergency Service and so are interested in previous waterways and potential flood zones. Perhaps we will talk about the buried tributaries of Johnstons Creek that I have yet to explore. I want to hear more of their stories about local streets that turn into torrents, and basement pumps, and flooded police cells.

Concrete Creeks. Excursion 10. The shark park.

Wednesday 10 June 2020

At the northern end of Smith & Spindler Park in Annandale there is a quaint arched footbridge across to AV Henry Reserve. After passing beneath this footbridge Johnstons Creek flows under a road bridge where vehicles swoop around the arc of The Crescent. The canalside pathway has a separate underpass below the road. I have chosen to follow this section of the canal on a rainy weekday in the hope of avoiding encounters with speeding cyclists on the shared path. I am the kind of pedestrian they hate – slow, meandering, crossing unpredictably from one side of the path to the other to take photographs.

The Man Who Walks Ahead drops me at Smith & Spindler Park and will this time drive ahead to meet me at Tramsheds. Before I set off I am drawn to a cluster of small brick building in the corner of the park. It is another Sewage Pumping Station, SPS 4. I am surprised to find the high chain wire gate ajar and I walk right into the compound, as have many graffitists before me. There is an outdoor dunny attached to the main building and inevitable jokes spring to mind. Is it connected to the sewer, I wonder. When I tell him about it later The Man suggests it might house a relief valve.

There is a steep dip in the claustrophobic tunnel under The Crescent. A friend later tells me that when she used to cycle home from Glebe she would have to take a long detour whenever Johnstons Creek flooded because the water in the underpass was too deep to ride through.

When I emerge I’m disappointed to find the creek blocked from view by safety fencing and Sydney Water banners. ‘Johnstons Creek naturalisation’, they read, ‘We’re improving the health of this waterway, creating a better place for the community to enjoy’.  I peer through a gap in the screens and conclude that things have got a lot worse before getting better.  It was in this stretch of the canal that a confused bull shark, said to be 1.8 metres long, was stranded in a pool when the tide went out one day in September 2009. Happily it escaped back to Rozelle Bay when the tide came in.

I am now in Federal Park. Larger than all the other parks and reserves that edge the western  side of Johnstons Creek, narrow Federal Park runs all the way from here to the bay.  At a place where two separate bridges cross the canal (one for vehicles, one for pedestrians) two men in high-vis jackets are earnestly discussing ground water and surface water. Beyond them I can see the rail viaduct.

When I walk under the viaduct I will have completed the whole length of Johnstons Creek proper. But that walk must wait for another day. Right now The Man is waiting in the carpark of Tramsheds, where the former Rozelle Tram Depot has been transformed into an eating emporium.  Erected in 1904 and preserved by repurposing, the depot was one of several imposing infrastructure projects built near Johnstons Creek around that time including, of course, the canal itself.

If there aren’t too many people we will be allowed to sit at a café for a cup of coffee rather than having to buy takeaway.  It’s still raining but a rainbow has come out.

Concrete Creeks. Excursion 9. A string of parks.

Sunday 17 May 2020

Johnstons Creek would have once been a pretty little bushland waterway but when the surrounding land was subdivided, houses and factories turned their backs on it. In 1838 it was described as ‘that invaluable stream of water’, but by 1892 it was condemned as a ‘fever bed’ with calls to commence the building of a canal because of the creek’s ‘menace to public health arising from the sewage nuisance’.

Our excursion this weekend takes us from one of the worst of those ‘nuisance’ areas at Wigram Road, to The Crescent in Annandale, and back again. The canal that was eventually built is wide but water is only flowing in the central gutter today. Signs warn us that this is a Flood Zone, so I’ll be back next time the weather is wild.

On either side of the canal is a string of tiny parks and reserves, each named separately, presumably as a way of keeping up with the backlog of municipal worthies who deserve recognition. In Canal Reserve we walk over several cheesy homilies neatly written in coloured chalk.

Beside JV McMahon Reserve we watch a pair of ducks emerge from where they have been dallying beneath a footbridge.

Near Minogue Crescent Reserve we see a woman practising solitary Twister beneath the arches of the area’s most impressive landmark, the Johnstons Creek Sewage Aqueduct.

In AV Henry Reserve there is a bubbling spring in the centre of a swamp which, a notice informs us, may be affected by sewage overflow.

We cross the creek by walking over the road bridge at The Crescent, then turn back and descend into Smith & Spindler Park where, with its wider grassy sward and smoother path, we now encounter the dreaded joggers, spandex cyclists, whole families on wheels, and off-leash dogs. We notice that a children’s playground has been reopened just this week.

To our left is the canal which, for some reason, has been blocked from view by a dense planting of casuarina trees. To our right, beyond the grass, is Nelson Lane, currently decorated at regular intervals with piles of discarded domestic ware, the product of lockdown busy-ness.

Our limbs still intact and our lungs too, we hope, we press on back to Wigram Road, via the narrower Hogan Park, where a town house dweller has annexed public space outside their back gate to create a canalside pleasure dome complete with outdoor chairs, a swing, pot plants and plastic grass.

Concrete Creeks. Excursion 8. The tunnel of love.

Wednesday 22 April 2020

Today we pick up where we left off just a few days ago at Chester Street footbridge, to see if it’s possible to walk beside Johnstons Creek canal as far as Booth Street. We find there is public access behind houses but the ground is rough and covered with leaves from overhanging trees. Garden rubbish tossed over from backyards, most of it large palm fronds, makes the going tougher. Mosquitoes are biting in the shade but ahead the canal makes an elegant S-curve and, backlit by the autumn sun, the arch under Booth Street becomes a Tunnel of Love.

We scramble up to the roadway via another mini-reserve, this one called Badu Park. Cyclone fencing, orange plastic barriers and a roadside port-a-loo signal that the bridge is a construction site. It’s being widened, the notices on the fences say, and will have better footpaths and a bike path. Hopefully the two present-day councils responsible came to an agreement about who paid for what without the years of bitter feuding and name-calling that went on between Leichhardt and Camperdown Councils when the present bridge was built around 1898 to replace an old wooden bridge.

Beside the canal where it emerges from under the bridge there is a quaint brick and sandstone Federation-style building, partially hidden by trees and fences. It’s SPS 3 or, as I later confirm from Sydney Water’s heritage listings, Sewage Pumping Station No.3 built around 1901.

To get a better look at SPS 3, I walk down a stump of a road and across a small bridge below the level of Booth Street. From here I can also see where the canal continues around a bend before it is joined by Orphan School Creek near Wigram Road. That confluence was the location for one or our earlier excursions.

This is as far as we are going today. There’s a café nearby but if we want coffee we must line up in an orderly and properly distanced queue.

Postscript. By coincidence, in the following morning’s Sydney Morning Herald there’s an article about a $20 million scheme to upgrade small public spaces in Sydney’s inner west. One of the projects is a shared pedestrian and cycle path to be constructed along Johnstons Creek from Wigram Road to Chester Street. That’s the same rocky route we have just taken. Soon there will be no tossing of dead palm fronds over back fences.

Concrete Creeks. Excursion 7. The tip.

Sunday 19 April 2020

It’s over three weeks since we visited this light industrial triangle between Johnstons Creek and Pyrmont Bridge Road. There have been other excursions in between but now I’m back to find out what happens to the creek beyond the forbidding metal fence where it drops into an open canal behind Water Street.  Just a few neatly kept little houses remain here, tucked between hulking factories and warehouses, and we have come on a Sunday hoping to avoid large trucks squeezing into delivery bays. I walk down a driveway between two houses in Water Street and find that it opens onto a gravelled space bounded on three sides by buildings and on the fourth by a thick jungle of banana trees, castor oil plants, convolvulus and asthma weed. With no machete available I can only peer down the steep slope for glimpses of the canal wall, recognisable by its symbiotic graffiti.

Frustrated by the banana jungle we move east to a wider industrial street that leads directly down to the canal. I have never been on Chester Street before but later I will read that there was once a household garbage tip amongst the houses on this side of Johnstons Creek. It was the source of much friction between the adjoining boroughs of Camperdown and Annandale in the late 1800s. For fifteen years countless  newspaper column inches were taken up with reports of council meetings and letters to the editor on the subject of the Camperdown tip, whose ‘deadly effluvia’ made the creek filthy and ‘endangered the lives of the residents of North Annandale’. There are no houses here now and no tip. Instead there is a motor repair business with a wild piece of wall art.

We walk down the hill to a newly-built footbridge over the canal. On the other side of the dip the street climbs up between the Federation houses of re-gentrified Annandale.

Everything here looks new, but the two playgrounds  are roped off to prevent children from disobeying social distancing rules. This tiny canalside reserve is called ‘Douglas Grant Memorial Park’ in honour of an Aboriginal man whose original name was Ng:tja. The survivor of a massacre, in 1887 he was taken as a toddler from his North Queensland home thousands of kilometres away and brought up in Annandale as a member of his captor’s family. His story is told on two plaques.  It does not end well.

By taking a short walk along where this narrow park skirts a series of backyard fences, I can look across to the place where I had earlier tried bush-bashing.  The clear band of water that I couldn’t see from the other side reflects the sky, but the graffiti is old and dilapidated, as if the renovation of the area has made the canal too public for spray painters.

This nook in Annandale is a revelation to me. But not to locals of course. Not the cyclists and joggers intermittently crossing the bridge. The two young men casually shooting a basketball. The squealing children doing wheelies on their scooters. Nor the three teenagers sitting at a picnic table and idly chatting not quite 1.5 metres apart.

Concrete Creeks. Excursion 6. The source.

Friday 10 April 2020

It is raining lightly and the urban currawongs are going joyously berserk as we set off. Having visited the mouth of Johnstons Creek we are now looking closer to home for its source, guided by an 1887 map of Sydney suburbs. We begin at the railway underpass in Liberty Street, Enmore, with its shredded posters. The Man Who Walks Ahead watches two bill posters posting on the opposite wall.

Crossing to the nearby roundabout I can see the spot that the map indicates as the beginning of the creek. It’s in a dip of what must have been a soggy paddock but is now Railway Avenue.

Tracing the creek from its source now becomes a matter of following the lie of the land and peering down grates in the roads to deep stormwater drains with yellow ladder rungs and sky glinting off water at the bottom.

We come to a corner where we can look down Salisbury Road. In the dip there is the paling fence that screens off Johnstons Creek where it modestly emerges from underground and continues its journey cosseted by an open air canal. But we have been there before so instead turn up the hill to imagine how rainwater runs above and below ground down towards the concrete creek.  In a back lane a piece of wall-and-pavement graffiti helpfully depicts this process for us.

We get suspicious glances from people sipping at paper cups while accompanying their raincoated children out for a scooter ride. At the end of the lane is a little café where customers queue obediently for their permitted take-way coffee. 

Our long walk has taken us through corner country where four suburbs meet. As we circle back to our starting point we find that those bill posters have renovated both sides of the underpass.
