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.
No 1 Canal Above Ground
Parts of No 1 Canal flow through large U shaped above ground concrete structures where the ground is on even or not suitable for below ground canals

The stars finally aligned to tackle your HEC Derwent Scheme caches.
Left home at 7am and arrived back at 7pm after driving some 560km and finding 33 caches.
This is a great series of caches, which took me to many places I've never seen with quite spectacular scenery and HEC engineering.
A quick find next to the large above ground canal.
Many thanks for an awesome series
....thoroughly enjoyed....cheers ST.
Accurate coordinates and the hint led to a quick find. The cache and contents were in good condition. Thanks Budgietas 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.

A road trip today to find plastic
Continuing up the road - an area I visited a couple of times while working in the area
Sainted the cache at 1640 hours with a quick, easy 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

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.
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
