Lowbidgee Day 6: coming into Balranald.

Southern Bell Frog community in the wetland behind my campsite.

Wetland sounds and scenes. Once, the whole of the Murrumbidgee plains would have flooded like this every year.


Today I got off nice and early again, but not before I had looked at the source of all of last night's noise there had to be a swamp somewhere up there from which the frog calls were coming. The area of environmental watering was much shallower than I had expected. It was at is deepest probably only about 15 cm deep and in many places only 5 cm. The frogs were loving it however and the forest and understory looked a picture of health. I took a few photos and was that impressed by the scene, I shared it straight away - including a short video to capture the frog noises which were few and quieter than during the night. Balranald is known for many things, but the symbol it has chosen to promote itself with is the Southern Bell Frog (also known as the Growling Grass Frog) which is listed as endangered in NSW due to habitat loss and the lack of regular natural floods. 

The Southern Bell Frog (Litoria raniformis) has suffered a considerable reduction in abundance and distribution throughout NSW in recent years (Tyler 1993, Sadlier and Pressey 1994, Mahony 1996, Osborne et al. 1996, Ehmann and White 1996). Once abundant along the Murray and Murrumbidgee Rivers and their tributaries from the Southern Tablelands to the South Australian border, the species is now only found in scattered locations throughout their former range. Suspected threats to the Southern Bell Frog include loss or fragmentation of habitat through draining of wetlands and prolonged periods of drought, predation on eggs and tadpoles by introduced fish species, infection by pathogens, particularly Chytrid fungus, degradation of habitat from pollution, salinisation and chemical use.

The Southern Bell Frog is listed in NSW as ëEndangeredí under the NSW Threatened Species Conservation Act 1995 (TSC Act). It is also listed nationally as ëVulnerableí under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and is listed as ëEndangeredí under the  (2000) Red List of Threatened Species.

One of the more interesting features of the Southern Bell Frog mouth). These teeth are used for holding Animals possess small vomerine teeth that are attached to a bone in the roof of the mouth and are situated between the choanae (internal openings of the nostrils in the roof of prey, which is then swallowed whole (Barker et al. 1995).

Males mostly call while floating in water among reeds between August and April (Robinson 1993). The call is a growling ìwaaah waaah waaahî that is similar to the sound of a distant motor boat or motorbike and is usually of about one second duration. 

Their original range included most of the Murray Valley and south to Tasmania, but are now listed to isolated pockets. In the NSW gov publication, they were only shown as being at the upstream end of the Barmah forest and ...

One of the aims of environmental watering has been to increase populations of these frogs, with some success. http://www.mdba.gov.au/what-we-do/environmental-water/river-murray/TLM-water-delivery/2013-14-tlm-environmental-watering-actions


In my boat once again and ready for the paddle to Balranald... wondering what the day would bring... grateful for the wetland treat and a world full of frog song.

Morgen Stund hat Gold im Mund (Schwäbisches saying). Morning hour tastes golden.

I love getting on the water early.

Reflections.

Reflections on a straight on the Murrumbidgee between Redbank and Balranald.

Balranald has a thick sticky clay soil (try getting it off your kayaking shoes) which holds water well, so a little goes a long way. The area between Redbank and Balranald, especially on the Southern side of the river, is used for flood control. As you paddle along the river, you occasionally come across regulators which can allow flood water to escape and spill onto the plains, and to let it back into the river to drain them. This is the main reason that there are so few people on this stretch of the river, and also why there is so much wildlife.

Murrumbidgee snags. Just after taking this photo I actually got stuck on it . It was much bigger than it looked.


Snags keep me on my toes. Though there is not much current, you are forever looking for the best and safest passage through.

Snags often reach from one side of the river to the other. It keeps the river quiet, provides habitat for wildlife and clean the water by bringing in oxygen. In many places only a canoe or kayak can slip through, making it an ideal expedition river.

Today I saw what could be described as the cutest eagle I have ever seen. Most animals flee as any human approaches; this one just looked at me right up until the last moment when it took off and landed in a tree high above the river to watch from a safe distance. On looking up my bird app, I found that it was a little eagle and that they are vagrants, that is they move from place to place - of not fixed address. The Steve McQueens of the bird world. When this particular young adventurer looked at me, his face seemed broad and teddy bear like, though I am sure that is not the impression he was trying to give. Must have been a young one. When he took off and landed on what he took to be a safe perch, a pair of wood swallows dive bombed it, even to the point of pecking feathers from its head. Enough was enough, it wasn't worth hanging around for all this hassle - he flew off. Pumped to have seen a new bird, I rounded the corner to find around a dozen of them circling in a thermal. They seem to like Balranald.

Negotiating snag in the Lowerbidgee...




Balranald is a community that suffered badly in the drought and is only now coming back. Little things matter a lot. "The couple who run the caravan park are a blessing to the town," said the lady who owned the bakery. "What they have done in two years is amazing. They have put this place on the map". For $10 for a campsite, great location and plenty of facilities, its no wonder it is popular. But many other things are happening in town. There is the history walk, which compares streetscapes then and now and tells tories of the town. An environmental walk, including a hanging bridge across the Murrumbidgee has been built and all around town are metal frog statues. The statues were made by a local artist, who used to be a panel beater, then became a priest, then took to riding harley's and now is an artist. Most have themes. The one outside the hardware for instance, is pushing a mower, by the river two are sawing a red gum log and another is doing a bit of gardening. In two weeks time the town is hosting its third '5 rivers outback festival' and as well as fishing competitions, ute musters, etc. they also have some big name bands coming. The streets are being tidied up, footpaths widened and resurfaced and city gardens planted. In the middle of town sat a man from the government next to new looking blue van offering small business advice. By the looks of how far he was into his book, he hadn't had too many customers today.




Balranald bridge. A welcome sight.

Balranald has frog sculptures celebrating the Southern Bell Frog all throughout the town. This one was outside the hardware shop.

Keeping with tradition started by the Millennium Paddle and Mike Bremer's Murrumbidgee Paddle I had a meal at the Services club. Here I met a group of three cyclists who had cycled from Broome, Perth and Adelaide respectively. We shared stories. They were happy to hear about the wildlife on the 'bidgee, roads can be noisy places.

Tomorrow I hope to get off early. The weir is in 17 km and I have another portage on my now well and truly dead trolley wheel. Tom the tyre man offered to pick it up from caravan park and repair it (how nice?) but he called to say that he would have to bring it back. he thought he had a tyre that small, but he did't and this one is well and truly buggered. Oh well, the buggered tyre is going to have to do one more portage worth of service.

Only two days to go and I am in the Murray! :)
This next section is meant to be one of the most beautiful.








Lowbidgee Day 5: Redbank towards Balranald.

Maps showing this section of the Murrumbidgee River (from Mike Bremer)

There is a steep bank with a clay ledge at the base of it, just after the Redbank weir reserve fence and before a series of water height measurement poles. It is possible to slide your boat down this bank. This activity would be easier with two people.

Balranald is 17km before the weir. The first you see of the town is a new bridge and a boat ramp. From this boat ramp you can walk into town. Around the corner is a good camping ground with a bank which is good to pull up on. 
Ready to leave Redbank, now just a slide down the steep bank to the river.
The day began with a steep slide down the river bank to the Murrumbidgee. Because the ground has sharp edged limestone in it which may scratch the boat, I lay down branches to slide my boat across, keeping it a few centimetres above the ground. It seemed to work, however I needed to hold onto the boat tightly to make sure it did not slide down into the water and continue the rest of the journey without me. 




Once in the water, I had just long enough to take in the beautiful morning sunlight spilling over the weir wall, bathing everything in a golden light, before the current took me so close to a snag which stretched from one side of the river to the other that I had to paddle to avoid becoming tangled. After this, the river opened up and paddling was good.
A few kilometres downstream from Redbank weir is a high red bank, where the river cuts through a sandhill; aptly named 'red bank hill' it is a great spot for a photo. Unfortunately just at that spot my GoPro which has 3000 photos left decided that it was full. I suspect the batteries are low and should have charged it last night, but didn't as the indicator said that it still had a full charge. It's getting a bit old and temperamental it seems. I should have charged. So no photo of redbank hill in the morning light. I recommend being there at that time though, and have your camera ready.


On the first corner below Redbank Weir is a snag which completely blocks the river; there is enough room for a tinny or canoe to slip through though.

The first ten kilometres were through river red gum forest. There have been at least 8 trees which stretched from one side of the river to the other. With most I could find a way through by zig zagging between the fallen trees as they stretched first from one side, then the other. Once I had to punch through some smaller branches. It is a good thing that everything is tied on securely. I think I have been lucky with the water levels. Even though Mike Bremers managed to get through at much lower water, I doubt that would have been possible with some of these trees.



Wedge-tailed eagle: wikipedia

There have been lots of wildlife, I have sighted sea eagles eight times already this morning, as well as a wedge tailed eagle and a kangaroo which had come down and I drink. The welcome swallows, so long my companions on the Murray trips are back. They are like little friends.




In the next ten kilometres I saw four fishing huts, one of them had a family camped nearby. It was made a timber off cuts, literally a slab hut. The roof had long since fallen in. Nether the less, a piece of history. I enjoyed a short chat with them and they enquired as to how and where I was headed. The last one was Breer Hut. This is marked on the map, but although it looks in good condition, seems a bit abandoned. Next to the hut, right on the river bank is the remains of an older hut, which has been converted into a stockyard.



Breer Hut. The original hut seems to have been converted into a stockyard. The water was more of a brownish colour, rather than the green that it looks in this photograph.

I saw two sacred kingfishers, returned from their northerly migration to the rainforests of Northern Australia and Papua New Guinea to breed in there'd gum forests of the Murray Darling Basin.



Sacred Kingfisher: Photo: MDBA The sacred kingfisher breeds in the river red gum forests of Australia's inland rivers before returning to Papua New Guinea, New Zealand and the Western Pacific Islands. It is called 'sacred' because the Polynesians believed that it had power over the waves on the ocean (wikipedia). What a mighty effort for such a small bird!
In the still low sun of morning restless flycatchers and willy wagtails forage for insects in the leaf litter. An emu sees me and first ducks behind the trunk of a large gum, but is curious, takes a peak and the follows for a short while. Not sure what made it more curious, the colour of my boat (bright red) or the occupants attempt to make emu noises.


Willy Wagtail: Photo: Climate Watch
Restless Flycatcher: Photo: Birdlife Australia Although they look similar to willy wagtails, they have a small crest, no cross looking eye-brow and a blue sheen to the feathers on their backs.

11:30 and I've already done 31km. Benefits of an early start. The river is quietening down as the day warms up. The trees are still full of bird call though: kookaburras, tree creepers and a bird with a call similar to a whip bird. On the river, the snags continue, but beaches are also starting to appear.



Snags frequently cross from one side of the river to the other.

Kangaroos, keep an nervous eye on what is happening down on the river.
Did you know that cormorants regurgitate their fish if they are too heavy to take off? To get it out their long neck, they shake their head violently until the fish flies out. I've seen black corms taunts do it twice now. The first time I thought it was trying to catch a fish that was just too big. It took a second time to work out what is actually going on. I saw a pelican do it yesterday too. They both can swallow surprisingly big fish - but can't fly with them.


Great Cormorant: found throughout the world. They regurgitate their fish not only to feed their young, but also to distract predators, or to allow them to escape them. I was amazed by the size of the fish they were able to swallow - sometimes as large as the bird itself.

Between the last paragraph and now I have spent my time improving my turtle spotting skills. They are elusive little fellas. After witnessing many splashes I had to conclude that the turtles were faster than I was: considering the relative sizes of the turtle to human brain and you can understand that this led to some degree of frustration. To become a turtle hunter I had to think like one. What would they naturally be afraid of? What would eat them? In a world Undisturbed by humans (the conditions they evolved in), threats could come from the sky. If I were a sea eagle, turtle would be like rump steak. So as a turtle I would have to always be watching the sky and the water in case they came in a low attack. The turtles were spotting me from 50m away, so I had to look further ahead than that and drift in. I also found that they prefer logs with a dark colour like themselves, that lie at a low angle to the water. I started to have success, eventually even being able to photograph one little fella. To be fair, I am no Harry Butler or Steve Erwin: the turtles are everywhere. I saw three on one log. Sometimes there just aren't enough logs.

Its shell is the size of dinner plate and does not have a snake like, or long neck.

For the last 30km I haven't seen any Pelicans. The river has been very windy and I have noticed them struggle with short runways. One bird, in an effort to make good an escape resorted to flying through the bush. It looked like it was about to crash at any moment. What I have seen is more sacred kingfishers, some quite loud and ferocious in their alarm at having a threat near their nest. I also saw my first peregrine falcon flying powerfully through the trees.

This bridge was not marked on the map and has a gate at each end, making it look provate. I think that it is made using army technology.

Hope to make ten more km today which will make a short run in to Balranald tomorrow. Camped at 62 km mark (Glen Avon Regulator), just off a fisherman's track (which I hope will keep the shooters in the distance away - they never like to shoot near where they know people to be). The banks are grey clay. I found an improvised boat ramp and ran my boat as far as I could up onto this before climbing out for a well earned break. Surprisingly, I had two bars reception. This would make it more likely that I would be able to update my blog, the photos from the day and let Ruth know that I was ok. I ate next to my boat to save carting all my food and cooking equipment to the top of the bank, where I had found a place safe from the many trees that lined the bank in this location. Dinner went down very well, and as the sun set for the evening, I retired to my tent to lie flat, rest and move out of reach of the mosquitoes that usually come out as night approaches. 





One of the unexpected highlights today was finding the paddle steamer turning (or passing) bays on some of the narrow stretches of the river. One, near Redbank, was particularly well preserved with no signs of silting or erosion. Almost worth a pilgrimage Peter Garfield? I have never heard of these before, but have no better explanation. They are not the beginnings of channels, or beginnings of the construction of regulators (as they are too big and in the wrong spots: not where the wetlands are) and they happen to be near stations where the river is narrow. I can just imagine in the old days how the steamers would have sounded their whistles regularly to let other boats that they were coming. If I remember the rules of the river correctly, the boat travelling downstream has right of way, because it is more difficult (or impossible) for them to stop. The paddle steamer coming upstream would have had to wait in a wide section. Sometimes these are many kilometres apart up here, so there would have been a lot of steam being blown. It would have sounded magnificent. What a loss when they were replaced by trains!
