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.
Wayatinah Intake
Nearby the water from Wayayinah Lagoon is taken into an underground tunnel, and later penstocks on its way to Wayatinah 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.
After continuing north we turned down the Long Spur Road and enjoyed a peaceful drive through the Wayatinah Forest Reserve. The cache was quickly found near the edge of the lake after we made our way past the spikey forest of small slender thistles. Its sad to see these weeds spreading through areas like this.
Thanks for this cache in the series Budgietas. GZ was quite wet but the container and contents were dry. This is a very pretty area on a clear summers day.
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 in a lovely location near the lake edge.
Many thanks for an awesome series
....thoroughly enjoyed....cheers ST.
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 many times trout fishing
Had some nice meals as a result
Sainted the cache at 1212 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

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
