Down-to-earth approach does it

A McNeill Drilling rig began working above the Clutha River near the Luggate Red Bridge yesterday, as Contact Energy investigates whether geological conditions are suitable for the construction of a hydro-electricity dam on the Clutha River near the Nook. Pictured are crew members Ryan Mawdsley (left) and Rolly Harrex, both of Alexandra.

The drilling company expects to be in the area for three to four weeks. Test sites are on both sides of the river.

Contact Energy's other possible Clutha River hydro dam options are at Queensberry, Beaumont and Tuapeka Mouth, which are at more advanced stages of geotechnical investigation. Contact Energy has not determined which of the four sites is its preferred development option.
