Description
HEC Derwent Scheme
Construction of the Derwent hydropower scheme began in 1934 and the last power station was commissioned in 1968.
There are two sections in the Derwent hydropower scheme – the upper and lower. This is because of the difference in how the water is stored in the sections. Visually the scheme resembles a Y shape.
The upper section of the scheme uses larger, deeper lakes for water storage than the lower section. The four main power stations in the upper section release water when it is needed to generate electricity. The upper section is formed from the Nive River system in the east and the Derwent River system in the west, making up the top of the Y.
The lower section is called run-of-river, which means water flows to power stations directly from a river, and cascades through a series of power stations. This means the same water is used to generate energy multiple times. There are six power stations in the lower section and they use water from the Derwent River multiple times. The lower section forms the ‘tail’ of the Y.
Repulse Dam
Repulse Dam is concrete arched Dam on the Derwent river. It holds back the water of Repulse lake so the water can be funnelled through Repulse Power Station

Logs
we had collected a few caches in the HEC Derwent Scheme series some time ago. As it was a pleasant, slightly overcast day we looked forward to visiting a few spots that hadn't seen us for many years as well as two that we had never been to.
When we arrived we found that the bailey bridge was indeed closed to vehicular traffic but glad that the means for walking on water was still in place. After reading Swamp's log we followed the road to this hide where we found the container well-hidden but almost full of water. This time the log sheet was extremely wet. After drying things the best we could we managed to make a mark on the log sheet before replacing everything.
Thanks for this cache in the series Budgietas. We were lucky that we had the area too ourselves today so we could hunt without having to wait for muggles to move on. The Hydro dams are so different that we always enjoy seeing these dams again.
Toda y I went for a little drive to this one.
Found on Monday 18 April 2022 at 1205

Should have just followed the road.....
Found after dodging muggle fisherman and son.
This one also had a fair amount of water in it, after fighting the spider and its eggs, the log was dry.
Thanks for the cache Budgie!
A road trip today to find plastic
My first time into this area
Totally impressed with the dam here
The over-flow on the dam was working a treat
One car here - the owner was below the bridge trout fishing
Sainted the cache at 1026 hours with a find that took a little more time than it should have
Didn't stick around too long as a tiger leach tried to get me - big buggar that it was, was not successful
Made 27 finds during a drive of 427 kilometres
That's 1 cache every 15.8km driven
The total distance walked finding the caches was 9.98km using 12968 steps while expending 1895 calories
That's 1 cache found in every 370 metres walked or 1 cache every 480 steps taken
Every cache found cost me 70 calories
TFTC and cheers

This is one impressive HEC scheme and we appreciate the time and effort gone into highlighting these locations.
Many thanks Budgietas for bringing us here. We shared a joint *FTF* with whitewebbs.
I spent the first years of my childhood in Tarraleah, and can vividly remember visiting butlers gorge power station and being driving under the spillway.
I hope you enjoy the series as much as I have enjoyed placing it
