EFFECTS OF DAM
F'ears For Fish And Wildlife (N.Z. Press Association) INVERCARGILL, July 12. Concern about the effects of damming the Waiau River was expressed to the Manapouri Commission of Inquiry by the Southland Acclimatisation Society. The Waiau, the society said, was a major spawning area for trout.
The society’s chief ranger (Mr R. R. Sutton) said the river contained brown and rainbow trout and the Atlantic salmon. It was the only New Zealand river containing the Atlantic salmon. The part-finished weir at Mararoa had already had an adverse effect on fish life in the river. Stopping the flow would result in overcrowding, which would result in a loss of condition in fish due to a drastically reduced food supply. A reduced flow might see periodic blocking of the Waiau mouth, and severance from the lake system could cause the disappearance of the rainbow trout and the Atlantic salmon. The reduction of water areas would probably be to the detriment of (he paradise duck in particular, Mr Sutton said.
