Trig? in Jindabyne

I found a trig (maybe) in Jindabyne, with tall four metal legs and a corrugated iron top vein, but the plaque underneath says Survey Mark. It has been put there by the Snowy Mountains Hydo. It looks like a trig, but I guess it isn't. Does anyone know about this?

Pending someone who knows better, a trig point will always be associated with a survey mark, however survey marks can be independent of a trig point. As far as I can tell a TS is a trigonometrical station so this looks like it's a survey mark associated with a TrigPoint. I would create a TP listing for this.

Have a look at The Surge Trig TP5375 which is similar to this one & has a SSM near it.

A search for TS1308 on the NSW SIX maps shows a TP that is located out in the Riverina and searching SIX maps for PM1308 and SSM1308 both returned locations up in the Walcha area. I confirmed the PM and SSM location on the NSW SCIMS website. Coupled with "Snowy Mountains Hydro Electrica...." being written on it reinforces, for me at least, that it is not a NSW TP. Looks to me to be a survey point put in by Snowy Hydro.

Cheers,
Michael.

P.S. NSW SIX maps are very helpful for finding trigs.

It not being a NSW Trig some people will say don't list it as a Trig Point, I on the other hand think it is a trig just not one listed by NSW.

We have one in Tassie that isnt a 'real' trig as it was placed by HEC (Hydro Electric Commission) https://geocaching.com.au/cache/tp0831 but it is a metal marker set in stone and it's at the top of a hill.

Do what you feel and see what people think, if there are views from GZ it's work sharing one way or another.

It does look similar. I logged that one in 2015. I think I will create a new listing, for the one I found. After I have logged today's cache finds...I am travelling :)

As far as I can tell the SMA (Snowy Mountain Hydro Authority) placed several hundred of these stations most but not all of which were registered with the NSW Land Dept, such as for instance TS7398SMA1322 instead of a name the SMA ident number was used.
I don't doubt that this is a Trig and was used as such. I would speculate that only the trigs useful after construction was finished were registered to check for land subsidence in the area.
