Forebay at Lloyd Mandeno Power Station

The structure in the right background is for raising and lowering the intake gates to the penstocks. There is a long wooden handle attached to a rake on top of the intake screen for removing debris.

On the left hand side of the structure are two Yagi UHF aerials for remote monitoring. In the back centre can be seen the two low pressure concrete penstocks.



Lloyd Mandeno Power Station Forebay and Canal

In the middle foreground there are floats roped together to warn the occasional canoeist not to approach the intake too closely.

Looking down the canal; from the Lloyd Mandeno Forebay


The canal is lined with a heavy plastic (butyl rubber?) membrane to prevent leakage. The light volcanic soil on which it is built erodes very easily.
