Lake Manawatu, a dam.

 

 The catch cry of the days is renewable energy throughout the land.  With the closing of the Manawatu Gorge (road not rail) it would be opportune to build a dam at the western end of The Gorge with a hydro plant in it's belly.

I propose that the dam be 30 metres high.  Power would be directed into the National Grid for the Whanganui, Manawatu, Hawkes Bay, Wairarapa and Horowhenua areas.

What is not known, how far back into the Woodville areas would the resultant lake reach? 

Thoughts??
