Highlights of the Trail
THERE are many wonderful sights to enjoy while walking or cycling along the Lake Dunstan Trail.
Here are some of the highlights:
CLYDE DAM
After decades of discussion and many different proposals about the placement of a hydroelectric dam on the Clutha River, construction of the Clyde Dam began in 1982.
The dam had to be redesigned when fears that a fault under the riverbed could be reactivated if the nearby Cairnmuir Fault moved, fracturing the dam, so a ‘‘slipjoint’’ was designed into the structure. A vast landslide stabilisation project also had to be undertaken before the dam was officially opened in 1994.
HALFWAY HUT
A stone miner’s hut perched on a small outcrop halfway along Lake Dunstan is a reminder of Central Otago’s goldrush days of the 1860s.
The simple structure represents many humble homes that dotted the landscape during a frenzy of activity as settlers from across the globe flocked to the region in search of the glittering metal that could turn poverty into plenty.
Visitors may not find a fortune but they can spend a penny at a remote toilet in the valley behind the Halfway Hut.
CAIRNMUIR LANDSLIDE
These distinctive terraced steps were a vast engineering solution to prevent rocks crashing down into the dam.
Constructed of welded wire mesh with rock fill, the steps are about 50 metres above the maximum lake level.
The 7m high construction is designed to divert rainwater away from the landslide so instead of causing rockfalls it will drain away and be directed safely to the lake.
CROMWELL HERITAGE PRECINCT
Before Cromwell’s main street was submerged under the waters of the new dam a collection of historic buildings were preserved, some rebuilt on higher ground and others restored to highlight their original use.
Now they serve as a charming corner of history, taking visitors back to the time of european settlement and goldmining frenzy.
Cafes, museums and art galleries offer a delightful range of wares, including many creations by local artisans.
