John White, Rurkikaka Creek within the Orepuki Catchment.
99 South Ltd is a dairy operation located just south of the Orepuki township, milking approximately 850 cows, with 400-500 cows wintered on the dairy platform. The topography of the property is rolling with a number of small gully systems, critical source areas and open waterways present.
The property is located within the Ruikaka Creek catchment that is part of the wider ACE Orepuki Catchment. Due to its close proximity to the coast and Longwood Forest, this area is subject to higher rainfall and coastal weather systems. The catchment is relatively small when compared to others in the wider Aparima catchment.
The landowner was interested in installing some sediment traps on his property for both water quality and biodiversity values and sought advice from Environment Southland to determine the best locations for the construction of sediment traps and wetland areas.
