Raising the wall will do nothing except cause more stress to an old dam that wasn’t designed to hold that amount of water . They need to build an overflow catchment dam so water can be diverted to it and re drawn from it so Warragamba Is kept at 70 % full , the overflow dam is placed to the south of warragamba and when warragamba reaches 70% we start pumping water to it and as warragamba drops we draw water from it - this gives some flood protection as well as drought protection . Even if this new dam Is higher up than warragamba we would use pumps to get the water up there then use gravity to get it back down .
Every so often I have dreams of the view at 4:35, the water level no longer gets close to that high because ground had literally been given. Where Hawkesbury River once snaked along, their is a small ocean and waves lap the shore lines between Windsor and the mountain/cliff side in the distance as most if not all the land in that area had either been purposely dugout... or washed away.
Raise the dam wall. Raising the Warragamba dam means: 1) you buy more time to do a steady release during long periods of precipitation, which can mitigate floods like these, and 2) you increase storage capacity during drought and hot El Nino years.
Raising the dam wall will only result in the flood zone wing changed to residential and development will commence, lining a few pockets. It is interesting to note who has a pecuniary interest in the sand quarries at Emu Plains which is flood zone. The fact that there have been many properties along the route of the river that has been mined but no housing has been permitted. Warragamba dam is a water storage facility NOT a flood mitigation dam and there is legislation in place which prevents the dam level being lowered however, during unprecedented La Niña events, smaller amounts could be released and give residents more clear warning, of pending disaster. This was NOT just direct flood water, it was a result of several factors, excessive rainfall, the fact that our area is a clay base, the three choke points that do not allow water to get away, clogged waterways, ridiculous amounts of development which prevent the water soaking and the release of water from Warragamba Dam. Sure, I live on a flood plain also but never in over thirty years, have I ever seen flood waters on our property, luckily did not get near the house. Nor have I ever seen water ‘gushing’ onto back paddocks in the manner that it did. No easy fix except a reservoir to begin with and let’s face it, it’s all about the money. A four thousand mile pipeline can be built across the Sahara Desert for gas, surely this country could build a pipeline and reservoir to relieve the dam instead of flooding out innocent tax and rate payers.
the higher you make any bridge the longer it needs to be and I cant help but feel that a "flood proof bridge" would go from the bells line of road all the way to Parramatta.
I totally agree with Matt, I have lived on this river for over 30 yrs first on a turf farm on the river at Cornwallis where I went thru a couple floods and they had a chart for a 100 yr flood and the water went back to Blacktown. I now live the other side, the safer side when the bigger floods hit. Forget about adding to the dam, stop keeping it at near 100 per cent.
true, but they did and we now live a proverbial bath tub, warragamba is the literal tap left on. so what to do? everybody moves out of the bath tub and or once more, humanity further alters the natural landscape for short term benefit not knowing the end result hoping for the best? No my friend, need to take time our be much, much more careful, I mean it would be nice to not live in flood plain but to then have access to so much water when bush fires roll through would be just as nice.
Oh NO ! out of control... In contrary ... EVERYTHING IS TOTTALY UNDER CONTROL from GOD ❗☝️ HE always knows What When Where How and Who ...So learn it to give a RIGHT nome to things. To not be a lier ! Thanks.

how did all those "new" housing estates end up on flood plains councillor?
Excellent video God bless all
Beautiful video yes yes yes
How about a road bridge across the flood plain instead of focusing on new developments in the Hawkesbury???
My old house was on Scarvell Ave, I wonder if it got flooded, came close when I lived there between 1979 and 82.
All the houses, school and shops look pretty new, how did they end up in a flood plain councillor?
The river needs dredging.

Don't forget their are another four dams on the Nepean not just Warragamba

Susan Templeton MP and Robyn Preston MP please build a 1:100 year flood proof bridge between Richmond and North Richmond now
the higher you make any bridge the longer it needs to be and I cant help but feel that a "flood proof bridge" would go from the bells line of road all the way to Parramatta.

Shouldn't have built on a Bloody Flood Plain! 🤦
