The Macquarie Towns–Pt. 3 of a series

When I was first married I lived in the Richmond-Windsor district of NSW. These two towns were a part of the 5 towns designated by Governor Macquarie because they were on high ground. A summary of the life of Governor Lachlan Macquarie can be found here.

The Governor, his wife and a few others set about doing a survey along what is now known as the Hawkesbury River, which is a part of the Hawkesbury-Nepean river system. Macquarie designated Richmond, Windsor, Castlereagh, Pitt Town and Wilberforce for the purpose of settlements because they were on high ground and people would be safe from floods.

Now fast forward to the late 1900s where the NSW government began to release new land for sale in those same districts. The problem is that this land was in the flood plains, and was not a part of the designated area. When I lived in the area, I lived in Cox Street, at the top end near the railway line. The parallel street is George Street. The newly released land is at the other end of George Street. In the 1978 floods that land was under water.

I see this as a potential for a real disaster in the future. The Warragamba Dam which releases water that feeds into the Hawkesbury-Nepean river system, has not been at full capacity for a very long time. This is because a lot of the rainfall was not over the catchment area, yet we had flash floods in Sydney, and in some parts of the Castle Hill district we even had tornados from time to time. However, last year, in 2010, NSW had heavy rains, and this means that the Warragamba Dam is closer to full capacity.

If, as predicted, there is more rain in NSW and if that rain causes the Warragamba Dam to reach full capacity to the point where the flood gates are opened and the spill is released, then there is in my mind no doubt that there will be a big flood once again in the Richmond-Windsor district, and with a lot of new housing estates being flooded. This is because these housing estates have been built on the flood plains. The surveyors, and those responsible for town planning have ignored the possibility of floods in the area.

Whilst I cannot prove my statements, that there will be a big flood in that region, this brings me to looking at the situation of Queensland, where Brisbane has seen flooding at the same level as that of 1974, which was also quite devastating. Some of the issues that I have raised here about the designation of the Macquarie Towns also apply to regions in Queensland where the town planners have ignored the floods of the past, and in my view they have become sloppy because they believed the big Globull Warming lie.
