Rehabilitation: from open pit to recreational
At closure, mine dewatering will cease, and due to inflows from both surface water and groundwater, the water level will begin to rise in the open pit. Left to fill naturally, it would take more than 20 years to fill to the desired level. To accelerate the filling of the lake, water will be pumped from the Ohinemuri River during medium to high flows subject to a number of conditions. This will
