The winds were wild today. There were several times that I almost couldn't turn around because the wind caught my bow, but most of the time my boat broke through the waves it whipped up comfortably. I was an hour late on getting off because of issues with the gps, so I pushed hard to make up time. From the foam at the base of Yarrawonga weir every westerly stretch had white capped waves on it, however the river made up for this inconvenience with good current averaging about 5 km an hour.
I experienced several squalls and rain showers, the stronger of these made a noise like a jet aircraft approaching. It made the trees bend and shake. There was a high chance that some would fall in, so I kept to the centre of the river. The river is so wide at the moment that no tree would have reached the middle. It made me extra cautious about my camping site. With such strong winds it was not going to be anywhere near trees, that was for sure.
At about 25km, I paddled past 'checkpoint A' for the Massive Murray Paddle (Murray Marathon), after first stopping at the original alpha. The tree at One Tree Beach, which is usually a refuge from the hot sun, was well out in the channel in over 2 metres of water. I pulled over in front of it take a photo #whereismylandcrew! The new checkpoint is just downstream, at Redbank station, which like all of the stations around here is situated on top of an ancient Sandhills.

John, who had been a horticulturist before moving to Langi Oonah, had also noticed what was happening to the trees. Without prompting from me, he also thought that it might be root rot (a soil fungus called Phytophthora, also known as cinnamon fungi), because of the way previously healthy trees suddenly lost condition and died. I have been watching trees like this too, it is different to die back caused by insects, drought, or prolonged flooding. The trees behave differently. Recognising root rot is part of horticultural training. In Germany it was part of my training as a landscape gardener, my former profession. It spreads through soil particles, on shoes, boats, cattle, it can even move in water: virtually unstoppable. If the death of the old trees was caused by cinnamon fungus, it would explain why the older suffering trees were clumped, why the trees next to water did worse than those a little further back on higher ground and why they often had so few roots. You can learn something from every step in life and from all people.

When John's wife (who was away at the time) heard that I was doing a study to help look after the river, she said "make sure you look after him". There are nice people in the world. These are two of them.
Tomorrow I make for Tocumwal in search of a dry campsite. I thought I might try Time Out Resort. It seems to be flood protected. Perhaps I can camp on their land.
If anyone reading this post had stories, or pictures of bank collapse, or tree decline (particularly river red gums), I would love to hear/see them.
