To-day Ken and I drove down to the Southern side of Yarramundi Reserve, one of our favourite places, as we wanted to escape from our self-imposed isolation, due to the corona virus outbreak.
Yarramundi Reserve is a place for public recreation and environmental protection and is located at the confluence of the Grose, Hawkesbury-Nepean Rivers. It is a place we often visit as we particularly like to photograph the birdlife in the area.
We were shocked to see the devastation of this beautiful area caused by the recent floods a few weeks' ago. We saw whole trees uprooted and lying on their sides and lots of debris lying scattered around the area. We were prevented from progressing any further at one point on the track, due to a trickle of water, too wide for us to traverse and had to be content to just look and see beyond this point. It was heartbreaking to see many magnificent trees completely uprooted and we feel it may take many years for this area to completely recover from the impact of this destruction.
Here was a tree uprooted by the floodwaters and lying across the track at a precarious angle. It was terrible to see trees in this state. The force of the water must have been very strong to cause whole trees to be uplifted.
We came to this point on the track where the water had created too large a channel for us to traverse. We turned back and went for a walk around the other side of the Southern lagoon where we saw further devastation. Trees and branches were lying across the path and we had to pick our way carefully around the obstructions.
Here is the Yarramundi Bridge across the river and, at the height of the floods, this bridge was impassable due to the high water level. When this happens, a flood notice is placed on a signpost along Hawkesbury Road, at Winmalee on the opposite side across from our house. This is to warn motorists that the bridge at Yarramundi is closed to all traffic.
Some of the debris caused by the recent floodwaters inundating this area. This picture was taken on the track around the other side of the Lagoon. We could see, from marks on trees, that the height the floodwaters reached was well above our heads and it was hard to imagine the area being completely under water!
"During the beginning of last century, sand was mined from this area to meet the demand for high quality river sand for public buildings, including the Sydney Harbour Bridge. Sand and gravel continued to be extracted until 1989. The extraction activities have altered the landform of the Reserve. The large lagoon on the Southern side of the Reserve is a flooded former excavation pit and now a refuge for many species of birdlife." (www.hawkesbury.nsw.gov.au)
The Reserve is prone to flooding and I can remember other times when this area has been damaged by flooding. In time, it will recover and I guess, when you put it in perspective, it is a natural occurrence.
