The Tuapeka Leffel Turbine

Selected for Google Maps and Google Earth

Seen from downstream in the tailrace, you can see the beams supporting the turbine above the tailrace.

You can see the wide wooden pulley out to the left of the pump in this photo. It would have used a flat belt to drive the common pump shaft, and getting these belts (and paying for them) was clearly an issue for the Tamati Gold Mining Company. It is recorded in newspapers of the time as being something they struggled with and when the company was wound up, the value of belts in stock was a factor in the summation of the company assets. The Leffel turbine, like most, needed a water-filled draft tube below it to function properly and that has rusted away, however it would have been directly below the curved outlet and hung down maybe 2 metres of which 1 metre would have been below the tailwater surface
