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.

 

 

Lake Echo Intake Tower

The water from Lake Echo flows into the canal starting behind the dam through the nearby intake tower.

We had been down south and, when our business was complete we decided to return via the Central Highlands and look for a few caches we had not found.
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 went back across the dam wall where we found two cars parked just before the start of the wall. Fortunately, they were facing away from us so we were able to disappear down the lower road and park close to the hide. Like all our other finds today good coordinates lead to a quick find of a nicely hidden container. The container was tightly wedged into place and it wasn't until we were able to prize it free that we found that a local rodent had gnawed its way through a small section of the base. Happily the cache placement prevented water entering and the container and log were safe and dry.

Thanks for this cache and the series Budgietas. We have enjoyed our visit to this series and the history you have supplied. We look forward to finding the remaining caches sometime in the future

Hi Budge
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 1426 hours
An old fishing area, right in the middle of the camping spot we used when fishing here
Some great fun had here

Thanks for the series - very informative
Thanks for taking the time to research the system and to place the caches accordingly
Cheers

I had to bypass the previous cache due to workmen in the area of the GZ. This was another quick find. Very Happy

Today we continued our journey around this impressive HEC scheme.

We had an awesome day exploring the area, with the added bonus of snow. We appreciate the time and effort gone into highlighting these locations, some not visited before.

Many thanks Budgietas for bringing us here. We shared a joint *FTF* with whitewebbs.

Joint FTF @ 11.30 am with Tassie Trekkers. Today we decided to finish off the HEC Derwent Scheme series of caches. We left home knowing we would come across snow as it had snowed heavily in the area on Sunday and Monday. We were not disappointed as snow drifts began appearing as we headed towards Lake Echo on Victoria Valley Road. The roads were slushy and there was snow in the fields, trees and road edges. We had a great day visiting more HEC infrastructure, some we had never seen before. The Hydro history is fascinating and what workers created here is amazing. By the time we got to Butlers Gorge there was hardly any snow. See photo of the wind farm in the distance. Added a log and zip bag as missing. Thanks Budgie for placing caches which drew us to this area. TFTC

I have had this series in my head for quite a while. A couple of recent events have prompted me to get this series out there.
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
