The currently proposed scheme on the Waimakariri river is to take 140 cu. metres per second from two sites. I think that that works out at 12 million cubic metres per day for irrigation. Should be able to grow a few cows with that lot. Many years ago I wallowed in the North Canterbury waters at various sites when I worked for the North Canterbury Nasella Tussock board. I often shared mud holes with the cattle and never caught mad cow disease. When? - I was on the hill one day when the boss came up and told us that John F Kennedy had been shot.
