Recall that about a month ago I posted – No evidence of warmer summers from Wollongong City Council swimming pool attendance figures
At that time I emailed Wollongong Council to ask about historic survey data re heights of their ocean pool walls – for my questions click on more below. Just got a reply saying – [Thanks for your enquiry. Unfortunately information on height of walls with respect to historical mean sea level is not available.
Any actual effects on the utility of pools have not been observed other than storm impacts.]
If anybody has ideas to access historic coastal survey data? Must be data in archives – I am sure our pioneers measured and recorded exactly where they were and where they built things on the planet.
I wondered if your Engineering Department had data on the heights of the
oldest built walls and how they related to mean sea level datum when they
were built.
Do you have modern survey data on the heights of those original walls?
I am just hoping to get an idea of sea level rise over the many decades
since the construction of your oldest pool walls.
Please do not take your time up sending me other information on sea level
rise – I am aware of that.
Do you notice sea level rise affecting the utility of your pools?
Hoping you might have some information from your archives.
Thanking you,
Just from observations within the family, going back over 80 years, nothing much has changed in the beach front pools at Newcastle either. Also from 50 years of personal observations of water level markers that I was told were installed for the Power stations in Lake Macquarie, the water level there has not changed at all.
My family lived on the beach at Merewether and also at Swansea on the channel entrance to Lake Macquarie since the early 1900’s. The older members of the family are over 90 and they cannot see any change in the sea level during that time.
