Catchment includes the Waikaka and Pukerau streams. The Waikaka Stream is the local water body for the wider Waikaka community in Eastern Southland. It is used for many recreational activities, such as swimming and fishing, and runs through many farming properties in the district. The community formed a Catchment Group in late 2017 to establish a way to manage the stream based on changing regulations and legislation from Environment Southland (Regional Government).
