A trip up to the dam today found that the water level of the dam has dropped from the normal level of 176 million cubic metres to around 139 million cubic meters.
This is over a period of five months.
Water management officer for PNG Power, Laun Medakou said the water levels were dropping fast.
He said they are now at 41% below full supply level.
“But we have made adjustments with load shedding to accommodate for this dry spell. We have now reduced our valves to 15 points (3.8 million cubic metres per second) from 8am-10pm and to 20 points from 10pm-8am.
