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.

 

 

Derwent River Pumping Station

At this point water is pumped out of the Derwent river up to No 2 Canal to allow this water to be used before naturally running down the derwent

The small water outlet has had a torrent of water gushing through, washing away rocks etc for 2m plus either side of the outlet.
Found cache in poor shape and now removed with CO permission.
Cheers ST.

We came over the Central Highlands today to Hamilton to look for a cache to continue our streak. With the target attained, we continued along the Lyell Highway to Bronte (detouring into Butlers Gorge) and found some of the HEC Derwent Scheme caches along the way.

Accurate coordinates and the hint led to a quick find. The cache and contents were in good condition. Thanks Budgietas for the cache.

"Hello Budgietas thank you for the cache.

Today I went for a drive to Butlers Gorge to find some caches. This is one of yours I found on the way. It was an easy find all in good condition.

Hi Budge
A road trip today to find plastic
Continuing up the road - an area I visited a couple of times while working in the area
A good spot to vist
Sainted the cache at 1654 hours with a quick find
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

Add to the walk for the last cache and this was an easy find. Weather is good for a day chasing caches. 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 @ 2.00 pm 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. Thanks Budgie for placing caches which drew us to this area. Not sure if we went the correct way to this cache but found it in the end.

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
