The Hawkesbury River floods - April 2024

Today, I toured areas affected by the flood as waters neared what we hope is their peak.
This flood is "moderate", meaning its level is not as bad as the floods we've seen in recent years.
At time of writing (8pm Saturday), the gauge at Windsor is at 9.07m and rising slowly.
Here are the peaks at Windsor for earlier floods:
Oct 2022 7.384m
Jul 2022 13.9m
Apr 2022 9.07m
Mar 2022 13.714m
Mar 2021 12.912m
Feb 2020 9.225m
I noticed some differences between this and earlier floods. More debris piled against the bridge at North Richmond (and I believe TfNSW didn't lay down the railings... again).
Yarramundi Lagoon is more swollen and earlier, indicating drainage changes from the Lagoon into the river.
Richmond Oval is a lake, probably a consequence of soils being waterlogged at the onset of the rain event.

    When is someone going to realise what Governor Macquarie acknowledged back in the 1850's - building in a floodplain creates huge risks and challenges. Not only do we not have serviceable bridges in Yarramundi and North Richmond, we lack other infrastructure to deal with fires and increasingly frequent weather events and developers are still being given rein to bring in more and more people into an already pressure situation! And yet, the neighbouring Council of the Blue Mountains continues to argue against raising the dam wall. Something has to change soon. It's the same communities that are being compelled to deal with policy failures and you have to wonder how long it will be before insurance companies just refuse to cover the risk!

    Gov Mac 1810- 1822, even more wise than you thought.

    Thanks for posting. I'm stuck on the other side of the North Richmond bridge so I can't check it out. Another god-awful mess to clean up, at Richmond, by the looks of it. It looks like I can get across via Windsor Bridge, so thanks for this info. I need to go to Bunnings because water has poured through my ceiling and ruined it. I gather most of this was caused by the failure to modify the Warragamba Dam spill-way so it has over-flowed again. This is Chris Minn's mess. Most of the over-flow should have been released in increments, instead, we cop a deluge. The water could otherwise, perhaps, be re-directed to the Penrith/Cranebrook lakes projects where it could have added to the lakes and been stored for the next drought. Apparently they won't do that, either.

    The river has flooded forever. Thats why the farmland is some of the best in the country. The Maquarie Towns were created for a reason, they were smart enough to drop the idea of building on the plains in 1809. Even raising the dam wall will only enlarge the capacity and provide more water security for Sydney. It wont have much effect on downstream flooding coming out of the Nepean, Gross etc. unless as others have mentioned the dam is kept well below capacity to absorb the Cox etc upstream- which wont happen. And yeah I can remember the 15m flood in 78 (1m of rain fell over 6 days) when South Windsor to Penrith across to Schofields and Pitt Town were under water. The water almost reached Woods Rd South Windsor. Richmond Rd was under 10-20' of water - the old houses down there used to be on stilts. So how are you going to stop that? More rezoning and pack them in - hope for the best planning? Shouldn't really be in the Hawkesbury region if you don't understand the river. Much like being in Queensland and being surprised by Cyclones. Richmond Oval is a drainage issue, not a flood issue.

    Its alright to take photos and spruke yourself up but unless something is done you might as well sit in Templeman's Office and do nothing with her.
