The stream’s water quality is measured by Environment Southland at a single point in the catchment, close to the confluence between the stream and the Mataura River. Therefore, current recording only reflects the cumulative impact of any agricultural or other activity that may be altering the water quality of the stream. 

This report presents the findings of a research project conducted at the University of Otago, assessing the overall water quality of the Waikaka Stream, and the management views of the local community. The report outlines how data was gathered through in-stream water quality measurements, and interviews with local farmers in the district. These results are designed to assist in future management of the stream, working towards improved water quality outcomes for the catchment.
