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.
Dee Lagoon to Brady's Lake Tunnel - Exit
An underground tunnel moves water from Dee Lagoon to Brady's Lake which feeds into the Tungatinah Power Station System

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.
We followed the road round to this cache and remembered that we had made an earlier visit to this site while searching for caches. After a short search we located the container which was full of water. The log sheet was too soggy to sign so we left a replacement. We got out the thick and thirsty tissues to dry out the container before replacing it as found.
Thanks for this cache in the series Budgietas. There was plenty of water following quickly down the canal.
Planned this trip to complete your HEC Derwent River Series over 11 - 13th August
On the way up, I found those left in Tassie Trekker's Series around Lake Crescent and Interlaken, before stopping at and staying two nights at the Great Lake Hotel
Today, I achieve my goal and completed your series with a round trip (from the pub and return) of of 177km; covering many loved fishing areas
Nineteen of your caches were found using 6698 steps in covering 5.3km on foot
The weather - very cold early morning, unlike yesterday no rain today until the nineteenth cache was completed - otherwise sunny and fine!
This cache was Sainted at 1212 hours
Great spot, great view
Another great fishing spot
Thanks for the cache
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
