To supplement this information, targeted and detailed short-term monitoring programmes are also implemented in some catchments. This report provides the results from more detailed investigations carried out in three catchments: Water of Leith Kaikorai Stream Waitati River and Carey’s Creek The Water of Leith and Kaikorai Stream are both located in Dunedin and drain typical residential and industrial areas. Both watercourses have many stormwater outfalls which compromise water quality. The Waitati River and Carey’s Creek have little development in their catchments. The upper catchments are forested while lower in the catchment, pasture dominates. Water quality is generally very good. This report forms a baseline study from which ORC and local community programmes can work together to address various issues in the catchments. It is hoped that these catchment programmes will promote environmentally sound practices which will sustain and improve water quality.
