Barossa & Happy Valley Reservoir Tunnels
Or are they off limits, being SA Water property?
Barossa one, looks interesting, but where do both of them end?
I would, if only I lived in SA :)
You will not get much specific info for such places from members in this public forum.
I suggest Google Maps, Wiki, Trove, or good old footwork ;)
All the best!
Eiher I'll post results here, or I'll end up on Ch9 news after being caught!
Clarendon Weir also most interesting!
I believe the Clarendon weir is accociated with the Happy Valley reservoir tunnel.
You'll find info on the heritage register, etc.

It's fed via a 5km long 1.8m diameter tunnel from Clarendon weir.faithinfate84 wrote:Is there anything interesting out at the Happy Valley reservoir? Always drove past wondering..
It's about 100m deep in parts.
I've been interested in the Clarendon Weir also of late. Clarendon Weir leads into Happy Valley Reservoir.sean0038 wrote: Clarendon Weir also most interesting!
Would be interested in knowing if this tunnel has enough height to walk upright in?
Drains are okay. [insta: awesomeadelaide]
never die wondering 
Well I won't back down, no I won't back down
You could stand me up at the gates of hell
But I won't back down

i investigated it a while back its definitely not tall enough to stand up in and is almost always flowing with water.. if you start at the clarendon end you could technically "float" all the way down to the happy valley side just near the reservoir as there is another opening!
both sides have high fences, razor wire and ABUS locks on everything
never die wondering
I believe that they replaced the old one so more water could flow but I’m not entirely sure
It's quite interesting, the tunnel that willl did was the OLD outflow pipe. The Happy valley water transfer pipe (Also known as dynamic pancake for some reason) used to come out the the left of where the new outflow and steel pipe is. You can see the old outflows headwall (weird high arched thing) as it's partially buried but the top sticks out. The old steel pipe that pumps into the reservoir was removed but you can still get into the old concrete tunnel that travels through the hill and into the reservoir. It has INCREDIBLY bad air because it's blocked on one end and there's zero airflow into it. I do a fuckton of drains and I was breathing extremely heavily and actually even turned around. There's almost nothing to see inside the tunnel except for roots that have crept inside. Oh, And you can't actually do the Barossa tunnel, I've been to the outflow and it is filled entirely with water because it starts underwater lol, that's why (If you've ever found it on google maps) you can only see one end and not the other like other Resi tunnels. They actually service the tunnel by blocking it off and even then they still use boats to go inside so that gives you an idea of how deep the water is. There's a star of David with a plaque on top of the outflow, and that's my proof I've been and aren't just talking out my arse, I didn't take photos sorry. Hope that answers at the very least the Barossa side of this thread.
