This photo shows an external view of the Manapouri Powerstation and Lake Manapouri.
At the top you can see the switchyard, and the pylons supporting the 220kV high-voltage cable span across the lake.
Below the switchyard at lake level are the seven head-gates that allow engineers to de-water the generation units so that they can perform engineering work. Behind the head-gates are the penstocks - tunnels in the rock that descend vertically some 200 metres to the power hall below. In front of the head-gates you can see a log-boom that prevents debris being swept into the turbines.
In the distance, below the transmission cables you can see the station control building.
